• Hexcel’s Composite Innovations For Aerospace, Automotive, Energy And Marine Applications At JEC World 2019 Hall 5 - Stand J41

STAMFORD, Conn. – At this year’s JEC World taking place in Paris on March 12-14, Hexcel will promote a wide range of composite innovations for customer applications in aerospace, automotive, energy and marine markets.

Aerospace Innovations

Hexcel’s HiTape® and HiMax™ dry carbon reinforcements were developed to complement a new generation of HiFlow™ resin systems, producing high quality aerospace structures using the resin infusion process. HiTape® was developed for the automated lay-up of preforms and HiMax™ is a range of optimized non-crimp fabrics (NCF). Both products incorporate a toughening veil to enhance mechanical properties, meeting the structural requirements for aerospace parts.

Visitors to JEC will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® reinforcements, and an Opticoms rib made with HiMax™ NCF. The Opticoms rib and I Beam were both manufactured using C-RTM (Compression Resin Transfer Molding). They were injected with Hexcel’s RTM6 resin in a process taking less than 5 minutes. The total manufacturing cycle for both parts was just 4.5 hours.

Also among the Aerospace exhibits, Hexcel will display a composite petal for a satellite antenna, manufactured by Thales Alenia Space Italia. The petal is part of a set of 24 deployable structural elements that form the large area reflector assembly used on board Low Earth Orbit (LEO) observation satellites. Thales Alenia Space Italia selected Hexcel’s HexPly® M18 prepreg for this application, acknowledging the superior mechanical and outgassing properties provided.

Another Hexcel prepreg application on show is a “zero” frame, manufactured by Aerofonctions for the engine area of Daher’s TBM 910/930 single-engine turboprop aircraft. Hexcel’s HexPly® M56 prepreg was selected by Daher for the “zero” frame – a product developed for Out of Autoclave applications that provides the same high quality and performance as autoclave-cured prepregs, from a simple vacuum bag cure in an oven.

With 50 years of experience behind its comprehensive range of high-strength, high-strain PAN-based carbon fibers, Hexcel continues to innovate, and is introducing two new fibers to its portfolio. HexTow® HM50 combines high modulus and high tensile strength, making it ideal for commercial and defense aircraft and engines. HexTow® 85 was developed specifically to replace rayon-based carbon fiber for ablative applications.

HexTow® carbon fiber holds the most qualified carbon fiber positions on aerospace programs in the industry and is the best unsized fiber available on the market. It provides excellent bonding interfacial properties with thermoplastic matrices and is the best-performing fiber for 3D printing applications.

Additive manufacturing is another area of expertise for Hexcel, using PEKK ultra-high performance polymers and HexAM™ technology to manufacture carbon-reinforced 3D printed parts. This
innovative process provides a weight-saving solution for intricate parts in highly demanding aerospace, satellite and defense applications. HexPEKK™ structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts with a new technology.

Hexcel is well known for its range of weight-saving, stiffness-enhancing honeycombs and the company adds value by providing a range of engineered core solutions to customers from facilities in the USA, Belgium and the newly opened Casablanca plant in Morocco. Hexcel’s engineered core capabilities enable highly contoured parts with precision profiling to be produced to exacting customer specifications. An example of such a part will be on display at JEC. Made from Aluminum FlexCore®, the part is CNC machined on both sides, and formed and stabilized with both peel ply and flyaway layers of stabilization. Aircraft engines benefit from a number of Hexcel core technologies including HexShield™ honeycomb that provides high temperature resistance in aircraft engine nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential re-use of material after a fire event.

Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core, or can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees Of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.

HexBond™ – the new name in Adhesives

Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil. The company has now decided to unite the range by marketing all of its adhesive products using HexBond™ branding. The comprehensive range of HexBond™ structural film adhesives, foaming adhesive films, paste adhesives, liquid shims, epoxy fillets and Chromium free liquid primers is suitable for a wide range of applications in combination with Hexcel’s prepreg and honeycomb products.

Automotive Innovations

Hexcel’s carbon prepreg patch technology provides an innovative way of locally stiffening and reinforcing metal parts, providing noise and vibration management functionality. HexPly® prepreg patches consist of unidirectional carbon fiber impregnated with a fast curing epoxy matrix that has self-adhesive properties, enabling it to bond to metal in a highly efficient one-step process. These key technology properties are demonstrated in an 18.5kg aluminum subframe (that is 50% lighter than steel equivalents), which was reinforced with 500 grams of HexPly® prepreg and tested by Saint Jean Industries. The part demonstrates a significant reduction in noise, vibration and harshness (NVH). Other benefits include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. With this technology Hexcel is a finalist in the JEC Innovation Awards 2019 in the Automotive Applications category.

HexPly® prepreg patch technology was also applied to a hybrid side sill demonstrator developed with Volkswagen and Dresden University to address future crash test requirements, specifically for electric cars. Combining fiber-reinforced plastic (FRP) with metal, the hybrid construction allows for optimum performance including weight savings, enhanced safety, increased energy absorption, battery protection in a crash situation and production flexibility.

Hexcel will also display a lightweight CFRP transmission crossmember produced from Hexcel’s high performance HexMC®-i 2000 molding compound. The transmission crossmember was developed in partnership with the Institute of Polymer Product Engineering (at Linz University), Engel and Alpex. As the part connects the chassis together and supports transmission it has to be stiff and strong, resisting fatigue and corrosion. Hexcel’s HexMC®-i 2000 was selected as the best-performing molding compound on the market, curing in as little as two minutes to produce lightweight, strong and stiff parts.
To produce the transmission crossmember HexMC®-i 2000 preforms are laid up in Alpex molds and compression-molded in a v-duo press that was tailored for the application by Engel. Ribs, aluminum inserts and other functions can be molded into the part using the single-stage process, reducing component-count. Any offcuts from the preforms can be interleaved between the plies of material to provide additional reinforcement in key areas - meaning that the process generates no waste.

Other Automotive promotions on Hexcel’s stand at JEC World include a composite leaf spring manufactured by ZF using HexPly® M901 prepreg. In contrast to steel leaf springs, composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. HexPly® M901 prepreg reduces the cure cycle to below 15 minutes and provides 15% higher mechanical performance, with enhanced fatigue properties. It also operates at high temperatures, providing a Tg of up to 200°C following a post cure.

Marine Innovations

Hexcel has a comprehensive range of products aimed at racing yacht and luxury boat builders that include America’s Cup, IMOCA class and DNV GL-approved prepregs, woven reinforcements and multiaxial fabrics for hull and deck structures, masts and appendages.

At JEC World Hexcel will display an IMOCA yacht mast manufactured by Lorima using HexPly® high modulus and high strength carbon fiber prepreg from Hexcel Vert-Le-Petit. Lorima is the exclusive official supplier of masts for IMOCA 60 class racing boats.

Hexcel’s HexTow® IM8 carbon fiber has been selected as the highest performing industrial carbon fiber on the market and will be used by spar and rigging manufacturer Future Fibres to manufacture their AEROrazr solid carbon rigging for all the teams in the 36th America’s Cup.

Hexcel’s HiMax™ DPA (Dot Pattern Adhesive) reinforcements are non-crimp fabrics supplied pre-tacked, allowing multiple fabrics to be laid-up more easily in preparation for resin infusion. Providing an optimal, consistent level of adhesion, they allow a faster and more consistent resin flow, as well as eliminating the use of spray adhesive for a healthier working environment and lower risk of contamination. Simply unrolled and applied to the mold or core layer before the introduction of resin, HiMax™ DPA fabrics are widely used in boat building, where lay-up times can be reduced by up to 50%.

Wind Energy Innovations

Hexcel has developed a range of HexPly® surface finishing prepregs and semi-pregs for wind turbine blades and marine applications. Providing a tough, durable and ready-to-paint surface without using in-mold coats, these products shorten the manufacturing cycle and reduce material costs. HexPly® XF2(P) prepreg is optimized for wind blades and has a ready-to-paint surface, straight from the mold, saving at least 2 hours of takt time.

Polyspeed® pultruded carbon laminates were developed for load-carrying elements in a blade structure and are manufactured with a polyurethane matrix that provides outstanding mechanical performance in terms of stiffness and durability. The blade manufacturing process is optimized, with increased throughput. The pultruded laminates are supplied in coils as continuous cross section profiles.
HiMax™ non-crimp fabrics using E-glass, high modulus glass and carbon fibers are also available in a wide range of unidirectional, biaxial and triaxial constructions. HiMax™ fabrics have applications throughout the turbine, from the stitched carbon fiber UDs used in the main structural elements, to glass fabrics and hybrids for blade shells and nacelles. There are also specialist applications such as lightweight fabrics for heated leading edge de-icing zones.

The “mtex+” is raising its profile and is moving to an attractive setting. The 8^th edition of the international exhibition entitled “Fair & Convention for Hightech Textiles” will be held in the new Carlowitz Congresscenter at the heart of Chemnitz for the first time on 9 and 10 June 2020.
 
“The “mtex+” is a trade event that experts from various sectors greatly appreciate on account of its emphasis on dialogue and in-depth contacts – and because everything is on the spot. The modern, exciting ambiance at the new venue facilitates our desire to create the best possible atmosphere for cooperation in a trusting environment,” Dr Ralf Schulze, Managing Director of C3 GmbH, the organising company, explains. “In its future form, the “mtex+” will act as a source of ideas and inspiration for developers and manufacturers as well as for users of all kinds of high-tech textiles, specifically including composites, to a greater degree than in the past. Textile composite materials are becoming increasingly important for many processors. That’s the reason why we’re transferring the textile themes of the LiMA lightweight design exhibition, which has been held alongside the “mtex+” in the past, into our new trade fair format. Lightweight textile design in all its facets will be one of the major emphases at the “mtex+”.”    
 
The major topics covered by the 8th “mtex+” will include process development, textile engineering, digitalised value-added chains, services with potential for use across different sectors as well as recycling. The highlights of the programme will include workshops on effective and sustainable production, smart textiles, acoustic textiles, a special exhibition on health and protective textiles as well as an entertaining network evening entitled “Excellent connections”.

The North-Eastern German Textile and Clothing Industry Association (vti) believes that this concept exactly matches the needs of its target audience. “Chemnitz is located at the heart of the Central German industrial and research region, which is developing with great dynamism,” says vti Managing Director, Dr.-Ing. Jenz Otto. “Any firm that presents its products and services here will find itself in a very interesting market. Located not far from the border with the Czech Republic and Poland, the “mtex+” will also act as a dialogue forum for potential cooperation partners across sector and international boundaries, both for these and other Eastern European countries.”
 
The “mtex+” will continue to be held in Central Germany’s industrial city of Chemnitz every two years in future too. 159 exhibitors from seven different countries (in conjunction with the LiMA lightweight design exhibition) attended the 7th edition in the spring of 2018. 22 percent of the approx. 1,000 trade visitors came from abroad.

The bags are utilized in the supermarkets of the Swiss food retailer Coop and the Austrian firm REWE International AG.

The Packnatur® reusable cellulose bag is particularly suited for the packaging of fruit and vegetables and serves as an ideal replacement for plastic bags. The jury provided the following reasons to justify the selection of the winner: The Packnatur® reusable cellulose bag comprises a long-lasting, reusable packaging solution made of a renewable raw material but not at the expense of food. It has very pleasant haptics and supports longer shelf life of food.

LENZING™ fibers are made from the natural and renewable raw material wood. For this reason, they are biodegradable. Moreover, they pollute neither rivers nor seas with microparticles washed out in the process of washing.

The Austrian State Prize for Smart Packaging was granted on the occasion of the 3rd Austrian Packaging Day. This year for the 58th time, the objective of this award is to highlight modern packaging solutions and excellent projects as best practice examples and thus put the national packaging industry in the international limelight.

"Datacenter in a box" is the new powerful, flexible and secure IT infrastructure solution for the textile industry of the future

Remscheid/Berlin – Oerlikon Manmade Fibers Segment Industrie 4.0 solutions for the production of polyester, nylon and polypropylene are based on the digitalization of the production landscape and the intelligent processing of the flood of data generated in this way. In the future, the segment will offer its customers a new powerful, flexible and, above all, secure IT infrastructure. The "Datacenter in a box" was presented for the first time at the OpenStack Summit in Berlin, Germany, to a broad specialist audience. The compact datacenter works on the basis of the open operating system OpenStack, which enables virtual computing in a secure private cloud environment.

Externally, the datacenter looks unspectacular: The box contains standard hardware such as server rack, network components, batteries for reliability, monitoring sensors and a few more things. But what counts are the inner values. The Open Source software OpenStack consists of many different services and allows the virtualization of a large pool of computing, storage and network resources in a flexible, scalable private cloud. This brings two central advantages: On the one hand, virtual operation reduces costs and simplifies configuration, adaptation and expansion of the IT infrastructure today and tomorrow. On the other hand, long-cherished wishes for high data protection are fulfilled, because a private cloud maintains secure, highly encrypted data connections away from the World Wide Web.

"The functional diversity of a cloud, operation and hardware in one's own four walls at the same time – our customers immediately understood these advantages" reports Mario Arcidiacono, specialist for Business Intelligence & Data Warehouse at the Oerlikon Manmade Fibers Segment. The IT architecture also guarantees infrastructure management without downtime, the system and virus protection are automatically kept up to date at all times. Another major advantage is the scalability of the hardware and software, which can be adapted to changing requirements.

OpenStack Summit: Project example with yarn manufacturer from Vietnam presented

With these trump cards and a project example, the Group segment confidently presented itself to a genuine specialist audience in mid-November. At this year's OpenStack Summit in Berlin, where thousands of cloud professionals met, Oerlikon Manmade Fibers Segment CEO Georg Stausberg presented the customer installation at Century Synthetic Fibre Corporation, which supplies many well-known sporting goods manufacturers. The Vietnamese producer of high-quality yarns not only uses the new datacenter, but also the connection to the new "Common Service Platform (CSP)" of the Oerlikon Manmade Fibers Segment as well as an innovative new dashboard solution in prototype status. In this case, the digital instrument panel supports employee communication during shift changes in the yarn factory and introduces agile methods into the work process. The board visualizes the progress of central key figures and operating parameters from the current production process. Based on this, the employees of the successive shifts can now exchange important process and quality information and possible instructions for action within a few minutes in a structured stand-up meeting. "For the customer this means an immediate improvement of the processes, and he can significantly increase the efficiency and quality of his employees' work," assures Joerg Gross, Senior Manager in the IT-architecture team at the Oerlikon Manmade Fibers Segment.

New IT-basis for the Plant Operation Center (POC) already successful established on the market

The fixed connection to the "Common Service Platform (CSP)" of the Oerlikon Manmade Fibers Segment plays a pioneering role in such solutions. This enables services and software updates to be provided smoothly, quickly and automatically. In this way, service applications can transform collected data into instructions or automated commands to secure and improve processes. For example, the secure availability of management solutions such as the Plant Operation Center (POC) for process monitoring can be increased and possible errors can be rectified very quickly. The new digital solution AIM4DTY (AIM = Artificial Intelligence Manufacturing), which was unveiled at the ITMA ASIA + CITME 2018 in Shanghai, China, a few weeks ago, can also be implemented in this way. AIM4DTY uses methods of machine learning, determines probable causes of errors in texturing and helps to improve quality during production.

Launch at ITMA Barcelona 2019

The Oerlikon Manmade Fibers Segment offers such remote-supported services on request. Data will therefore only be transferred to the “Common Service Platform (CSP)” with the customer's consent. In addition, all data is processed in accordance with the new European General Data Protection Regulation (GDPR) and all other international data protection standards. Against this backdrop, the Oerlikon Manmade Fibers Segment plans to provide its datacenter with graded or customer-specific solutions: from complete service to provision with customer training for its own operations. After initial practical experience with several pilot customers, the segment intends to launch its offering on the market next year and officially present it to the textile industry at ITMA 2019 in Barcelona, Spain.

New products for photopolymer and laser sinter printing methods from BASF 3D Printing Solutions GmbH (B3DPS) are on show from November 13 to 16 at Stand F20 in Hall 3.1 at this year’s formnext fair in Frankfurt. The BASF subsidiary is also announcing several new partnerships for the development and distribution of groundbreaking 3D printing solutions and products.

B3DPS has entered into a strategic partnership with the US company Origin, San Francisco, California for the further development of photopolymer printing processes. “Within the framework of an open business model, we are combining BASF’s material know-how with Origin’s expertise in printer software programming and the manufacture of the corresponding hardware,” explained Volker Hammes, Managing Director BASF 3D Printing Solutions GmbH. The collaboration has already shown the first signs of success. Origin has developed a new printing method where BASF’s new Ultracur3D photopolymers can be processed particularly well. The technology offers an optimal combination of a good surface finish and high mechanical stability, while also allowing for high material throughput.

B3DPS is working together with Photocentric, a manufacturer of 3D printers and their corresponding software and materials, on the development of new photopolymers and large-format photopolymer printers for mass production of functional components. Based in Peterborough, UK and Phoenix, USA, Photocentric has developed and optimized the use of LCD screens as image generators for its own printing systems. The two partners plan to offer the industry 3D printing solutions that replace parts of traditional manufacturing processes such as injection molding for small series, as well as enabling the production of large components.

The objective of the cooperation with Xunshi Technology, a Chinese printer manufacturer headquartered in Shaoxing, and operates in USA under the name Sprintray, will be opening new fields of application in 3D printing for the Ultracur3D product range of B3DPS.

Ultracur3D specialties for photopolymer printing processes
B3DPS has grouped well-established and new photopolymers designed for the respective 3D printing processes under the brand name Ultracur3D. BASF has developed unique raw materials for its new products that enable special part properties.
“Our Ultracur3D portfolio enables us to offer customers various UV-curable materials for 3D printing that provide far better mechanical properties and higher long-term stability than most available materials,” explained András Marton, Senior Business Development Manager at B3DPS. He added: “These materials have been developed for functional components that are subject to high stress.”

Expansion of distribution network for filaments
Innofil3D, a subsidiary of B3DPS, is entering into a partnership with Jet-Mate Technology, based in Tjanjin, China, for the distribution of plastic filaments in China. In parallel, a distribution agreement has been concluded with M. Holland in Northbrook, USA for the distribution of filaments in USA. “Since the USA is the largest market for filaments, we intend to strengthen our activities there,” said Jeroen Wiggers, Business Director 3DP Solutions for Additive Extrusion at B3DPS, adding: “Asia is another important market for us. We will be developing further distribution channels there and putting our Ultrafuse filaments on the Asian market in 2019.”

BASF’s portfolio of filaments for 3D printing are comprised of two categories; the well-established Innofil3D filaments based on generic polymers for conventional applications and polymer-based Ultrafuse filaments for advanced formulations used in demanding technical applications. One of the broadest filament selections on the market, this portfolio covers customer requirements ranging from prototype to industrial-scale production.

SLS: new 3D printing material with fire protection classification
New flame-resistant Ultrasint Polyamide PA6 Black FR meets UL94 V2 fire protection standards and is a new material class for use in selective laser sintering (SLS) processes, distinguished by high stiffness and thermal stability. In cooperation with one of the global leaders of public transportation vehicles, B3DPS has developed new components that meet vehicle fire protection requirements. “Together with our partner, we are currently producing prototypes, spare parts, and small series components, and are working to further improve flame resistance to meet additional certification specifications,” explained Hammes.
BASF introduced Ultrasint Grey PA6 LM X085 at AMUG this spring and now is followed by another product on show at formnext. Ultrasint PA6 Black LM X085 is based on polyamide 6, and can be processed at 175-185 degrees Celsius therefore making it suitable for most current SLS machines.

B3DPS adds polypropylene to its 3D printing portfolio
Through the acquisition of Advanc3D Materials GmbH in July 2018, B3DPS has expanded its range with numerous materials for use on laser sinter machines, including polyamide Adsint PA12, Adsint PA11, Adsint PA11CF and Adsint TPU flex 90.
Ultrasint PP is a special highlight. This polypropylene-based product exhibits outstanding mechanical properties and is frequently used in standard industrial production as it offers a good balance between price and performance. Ultrasint PP is distinguished by excellent plasticity, low moisture uptake, and resistance to liquids and gases. Prototypes and small batches can now be produced from the same material as used for traditional serial production. Post treatments such as thermoforming, sealing, and dyeing can be performed after printing.

• Unique, patented 3D printing process enables production of large-scale components
• First direct investment by BASF Venture Capital in a company in China

BASF Venture Capital GmbH is investing in Prismlab, a leading provider of 3D printing processes and 3D printers, headquartered in Shanghai, China. Prismlab has developed a patented printing process that is characterized by a very high printing speed, high level of precision and lower printing costs. BASF’s venture investment will enable Prismlab to further accelerate its product development and innovation while strengthening its market reach to the global market.

“This is our first direct investment in a Chinese company,” said Markus Solibieda, Managing Director of BASF Venture Capital GmbH. “The trailblazing technology from Prismlab allows large and stable components, such as medical braces and anatomical models, to be 3D printed for the first time. This investment supports BASF’s strategy of actively advancing our technologies and expanding our product offering in the 3D printing sector.”

“China is transforming from a manufacturing-driven to an innovation-driven economy. This investment in Prismlab reflects our commitment to further expanding our innovation capabilities in China, and BASF Venture Capital plays an important role in helping us identifying potential partners that lead us to success,” said Dr. Zheng Daqing, BASF’s Senior Vice President, Business and Market Development Greater China.

“The 3D printing technology must continue to evolve before it is set to change the world. At Prismlab, we aim to spearhead and accelerate that change by providing solutions through specialized customization. The investment allows us to stay laser-focused on our R&D capability, a key factor to achieve that goal,” said Mr. Hou Feng, Founder and Chairman of Prismlab.

Prismlab has developed a patented 3D printing process, “Pixel Resolution Enhanced Technology”, based on stereolithography (SLA). SLA allows comparatively large components to be produced using light-curing resins. Prismlab’s technology increases the printing resolution without compromising printing speed. In order to increase the amount of energy brought into a pixel, Prismlab’s technology divides each pixel in the resin into several small sections, which can be cured individually by exposure to LCD light. This makes the energy input into each pixel significantly higher than similar processes that expose each pixel to light once. This allows comparatively large and stable components or numerous parts to be printed in the same production step. With the use of LCD light, it also reduces process costs. This advantage opens opportunities in the footwear and furniture industry.

Along with this patented process, Prismlab also markets 3D printers and other related services. The Prismlab technology can be used in various key customer applications, including invisible braces, and anatomical models for medical, and education and training purposes.

SLA uses a laser for layer-by-layer curing of a photopolymer solution to shape the required workpiece. SLA and LCD based printing processes determinate the size, stability, and usability of the components to be produced as they are limited by the size of the light spot and the intensity of the light.

At the Composites Europe in Stuttgart /06 - 08 November 2018), the Institut für Textiltechnik of RWTH Aachen University, short ITA, will be showing products, components and machines along the fibre composite process chain. The ITA will present itself at the booth of the Aachen Center for Integrative Lightweight Construction (AZL) in hall 9, booth E70. Various demonstrators will be used to present selected innovative processes and products over the individual steps. The exhibits come from different fields of application: From mobility applications to the construction sector. Here is an example from the field of "construction composites":

With the concrete bar stool with hybrid carbon reinforcement, the ITA demonstrates that textiles as reinforcement structures for concrete elements allow a enormous geometrical freedom of Design. So far, manual positioning of the textile reinforcement used to be time-consuming and complex, as permitted tolerances are in the millimetre range. Thus the production mainly contributed to the high costs of textile concrete.

At the ITA, the two industrial partners Albani Group GmbH & Co. KG and DuraPact 2.0 Kompetenzzentrum Faserbeton GmbH developed a new hybrid reinforcement with integrated spacer. This hybrid reinforcement reduces the time required to position the reinforcement by up to 60 percent and thus makes the material significantly more

The new, cost-effective hybrid reinforcement contains an integrated spacer and thus faciliates the positioning of dry and coated reinforcements. The integrated spacer allows several layers of reinforcement to be stacked quickly, allowing the desired degree of reinforcement to be set. The hybrid reinforcement consists of a carbon or glass fibre grid joined with a permeable polyamide mat and will be available in roll form from industrial partners in the near future.

The Mechanical Engineering Industry Association (VDMA) has awarded two prizes to graduates of the Institut für Textiltechnik (ITA) of RWTH Aachen University - the dissertation prize and the creativity prize of the Walter Reiners Foundation of German Textile Machinery 2018. ITA alumnus Dr Benjamin Weise was awarded the dissertation prize for the development of novel fibres for textile charge storage devices. For their work on a guide to 4D product design, Jan Merlin Abram and Aalon Tal (both ITA students) were honoured with the creativity prize. The dissertation prize is endowed with €5,000 whilst the creativity prize contains a one-year scholarship of €250 per month. Peter D. Dornier, President of the Walter Reiners Foundation and Chairman of the Management Board of Lindauer DORNIER, presented the awards on the 18 September 2018 at the 18th Textile Machinery Forum in the Digital Capability Center in Aachen, Germany.

Graphene revolutionizes all-in-one - supercaps, reduction of terahertz radiation and antistatics

In his dissertation "Development of graphene-modified multifilament yarns for the production of textile charge storage devices", laureate Dr Benjamin Weise developed novel fibres made of polyamide and graphene and further processed them into textile surfaces. The newly developed polyamide graphene fibres are featuring a multitude of advantages:

• Due to their high performance in the charge storage area, they are predestined for use in double-layer capacitors, so-called super capacitors, or supercaps in short. Compared to lithium-ion batteries, supercaps offer significantly higher power density and a longer lifetime as no chemical reactions are taking place. towing to the graphene platelets in the filaments, it is now possible for the first time to integrate a charge storage device directly into a textile without having to sew in a rechargeable battery. This new fibre is therefore suitable for prospective use in smart textiles, for instance in a textile defibrillator.
• The new graphene-modified polyamide fibres can attenuate inident terahertz radiation up to 25 % of their original intensity. Terahertz radiation, for example, offers transmission rates of 100 Mbit/sec and is therefore of high interest for high-performance wireless communication. However, the radiation could damage sensible electronics as in aircrafts if this technology will be used widespread. Consequently, the shielding of the radiation is of high importance, e.g. in the form of fibre composite components in the aircraft, which protect the on-board electronics.
• As the fibres are showcasing a dissipative electrical conductivity, personal protective equipment is another prospective field of application.  

The development of a pilot process for graphene-modified fibres and the production of textile demonstrators are novel and disruptive attainments of Dr Weise’s PhD thesis and the reason for the award ceremony to him. Due to its outstanding properties, the European Union is funding research on graphene within the frame of the "Graphene Flagship" with an overall budget of one billion Euro (source: http://graphene-flagship.eu/project/Pages/About-Graphene-Flagship.aspx).

Modular product design of 4D products is now possible in simplified form

How can three-dimensional products change their shape over time and thus become "four-dimensional"? The students Jan Merlin Abram and Aalon Tal provide answers to this question in their project work "Leitfaden zur Auslegung hybrider morphender Textilien am Beispiel eines Scharniers" (Guidelines for the Design of Hybrid Morphing Textiles Using the Example of a Hinge), for which they were awarded the creativity prize. In their work, the students offer a guideline for the development of a four-dimensional textile from the idea to the demonstrator. Four-dimensional textiles, for example, consist of a hybrid material of elastic textile on which three-dimensional structures are printed. The fourth dimension describes the change in shape and/or a property over a defined period of time (= morphing).  This change is caused by external influences such as light and heat.

Every year, the Foundation of the German Textile Machinery awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the smartest student research project. Further prizes were awarded to Eric Otto, ITM Dresden, and Susanne Fischer, Reutlingen University.
