From the Sector

• Clean Technology. Smart Factory.

Remscheid – Oerlikon invites all visitors to this year's ITMA in Barcelona on a journey into the future of manmade fiber production. From 20 to 26 June 2019, the world market leader will show all its guests its vision of a sustainable and automated manmade fiber production in a virtual 4D showroom at its 1,000 m² stand in Hall 7, A101: "Clean Technology. Smart Factory." is the motto of the future. And this is only a stone's throw away from reality at the stand. Because today Oerlikon is presenting four world premieres for efficient machine and plant concepts in a new, innovative industrial design. Together with numerous other innovations, all this forms the new DNA of the Oerlikon Manmade Fibers segment.

The challenges for the manmade fiber industry are manifold and Oerlikon shows its customers solutions:

1. Choosing the right business model
Price pressure on fiber and yarn manufacturers is growing due to global market consolidation. Here it is important to position oneself correctly. Are you producing polyester, nylon or polypropylene for the niche market and skimming off good margins with innovative products and ingenious material properties, or are you looking for business success through economies of scale in the volume market such as the constantly growing apparel sector? Oerlikon has the right answers for both business models. And the most important thing: the market leader supplies all solutions from a single source. See for yourself at the world premieres of the machine and system concepts of WINGS FDY PA6, BCF S8 Tricolor and the revolutionary eAFK Evo texturing machine.

2. Finding alternatives for good personnel
Finding good operators in the manmade fiber industry is becoming increasingly difficult, even in emerging industrial nations such as China, India and Turkey. The solution is obvious. What, for example, the automotive industry achieved years ago with the 3rd Industrial Revolution is now also taking its course in the textile industry. And at the same time it is even shifting up a gear. In the next step, automation in combination with digitization will lead to new, sustainable production. Oerlikon will be showing how automation and digitization interact at ITMA. Self-learning machines and systems, artificial intelligence (AI), remote services and edge computing are just a few of the key words in the digital half of the new Oerlikon Manmade Fibers DNA.

3. Guarantee quality and traceability
The qualities of the fibers and yarns must meet the highest demands and their production must be traceable throughout the textile value chain. This no longer only plays an important role in the automotive industry, where safety is of paramount importance. Other branches of industry that use fibers, yarns and nonwovens also want to know where the raw materials they produce for consumer articles come from. Legal regulations are demanding this more and more frequently. Oerlikon offers optimal solutions with its DIN ISO certified manufacturing processes. More than half of the world's manmade fiber producers are convinced every day that the qualities produced on Oerlikon Barmag, Oerlikon Neumag and Oerlikon Nonwoven equipment are right – and all visitors to ITMA can do the same on site.

4. Efficient and sustainable production
In the future, the materials produced from manmade fibers must become part of a further improved global recycling economy. The recycling of polyester – with over 80% market share the most frequently used manmade fiber in the world – has not only been on the agenda since today. Oerlikon already has solutions at hand: from PET bottles to fibers and filaments, to textiles and carpets. ITMA is the next step. With the VacuFil® Oerlikon in cooperation with the subsidiary company BBEngineering presents the world premiere No. 4 – a recycling solution within a running polyester production with a waste-free approach.

Vision becomes reality
The Oerlikon Manmade Fibers segment thus demonstrates what the ITMA in Barcelona promises as the world's leading trade fair for textile machinery and plant construction: "Innovating the world of textiles – sourcing for a sustainable future". In Hall 7, A101, this is already reality.

At ITMA 2019 in Barcelona from June 20-26 FONG’S Europe, a member of CHTC FONG’S International Group, will be providing details of its new THEN Supratec LTM hydraulic long-tube dyeing machine.

This machine is distinguished by the ability to vary the angle of the Then Flexkier for either dry (jet) or wet (overflow) mode dyeing, in order to optimise the dye liquor ratio – from 1:15 down to 1:4 – depending on the materials being dyed.

This translates into considerable savings in auxiliaries, water and energy.

The Supratec LTM is suitable for the treatment of both woven and knitted fabrics ranging from the most sensitive articles to heavyweight materials within the weight range of 25 g/lm to 380 g/lm, and operates at very low tension due to the extremely low lifting height between the variable nozzle and the plaited fabric.

“Existing Supratec machines on the market are providing excellent performance for a wide range of delicate synthetic fabrics, from polyester to polyamide with high content of elastane,” says FONG’S Europe Director of Sales and Marketing Richard Fander. “Heat-setting can often can be avoided, which improves the handle of the material and saves costs and the lengthwise-elongation of the fabric being treated is lower than on winch-driven machines.”

The innovative technology addresses the growing need for on-demand textile design and production

Kornit Digital, a global market leader in digital textile printing innovation, has announced the introduction of the new Kornit Presto, the only industrial single-step solution for direct-to-fabric printing. The Kornit Presto solution eliminates the need for pre and post treatment of fabric and allows for high-quality printing on a broad variety of fabric types and applications. The Kornit Presto does not consume water in the printing process, making it a environmentally friendly solution.

The new Kornit Presto comes with the NeoPigment Robusto, a Pigment-based ink. Implemented into the Kornit NeoPigmentTM process, the Robusto provides above industry standard wash and rub results and exceptional color fastness across a wide fabric and application range. The Robusto enjoys faster physical and chemical bonding characteristics, enabling a significantly shorter curing time, while providing quality and a wide color gamut.

The Kornit Presto solution suits a wide range of business and application needs in a variety of industry segments, including fast growing segments within the on-demand fashion and home décor markets. It is a highly productive solution, available in multiple configurations and able to print 450 square meters per hour.

Gart Davis, CEO at Spoonflower, the world’s first web-based service for custom, on-demand fabric and design creation and a long-time Kornit customer, commented, “We were thrilled to be able to test the new system and found the Presto to be in a class by itself; it prints beautifully on all kinds of fabrics, in a single-step, with an environmentally friendly dry process, and now at a multiple of productivity.  Our partnership with Kornit continues to be fundamental to our mission to make custom fabric accessible to designers, creative individuals and small businesses all over the world. We can’t wait to get going.”

Swiss textile innovator HeiQ partners with BUFF® on their new CoolNet UV+® fabric to stay dry and feel cool. For 25 years, BUFF® has premiered and innovated the tubular headwear category. Headquartered in Spain, the company was founded to keep warm the founder’s neck and head during his crosscountry motorcycle rides. Today, BUFF® continues its heritage of quality and reliability of multifunctional headwear.

HeiQ Smart Temp is an intelligent thermoregulation technology. Cooling is activated by rising body temperature and deactivated once cooling is complete. HeiQ Smart Temp keeps the wearer cooler, dryer and more comfortable.
“HeiQ and BUFF® have a shared vision of quality and reliability in our products. With the new CoolNet UV+® fabric, we are pleased that our HeiQ Smart Temp technology will allow the consumer to Stay Dry and Feel Cool”, says Christian von Uthmann, HeiQ’s Chief Sales Officer.

Just like the first product from BUFF® in 1991, the new CoolNet UV+® was developed to keep customers safe and cool from the sun’s dangerous UV rays. Today the fabric is a recycled performance polyester microfiber with HeiQ Smart Temp’s activated cooling technology to keep the wearer cool and comfortable. The fabric also includes UPF 50+ sun protection, offers a 4-way ULTRA stretch weave and is 100% seamless for the perfect fit.

• 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.

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.

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.

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.

• Mit einem Festakt haben Dr. Eva-Maria Stange, Staatsministerin für Wissenschaft und Kunst des Freistaates Sachsen, Prof. Gerhard Rödel, Prorektor für Forschung der Technischen Universität Dresden, Prof. Hubert Jäger und Prof. Chokri Cherif am 02.11.2018 das Carbonfaser-Technikum des Research Center Carbon Fibers (RCCF) eröffnet.

Das RCCF, eine gemeinsame wissenschaftliche Einrichtung des Instituts für Leichtbau und Kunststofftechnik (ILK) und des Instituts für Textilmaschinen und Textile Hochleistungswerkstofftechnik (ITM) der TU Dresden, wurde gegründet, um die Carbonfasern vom Faserrohstoff bis zum fertigen Bauteil zu erforschen und neue Eigenschaften und Anwendungsmöglichkeiten zu entdecken.

„Sachsen verfügt in der Schlüsseltechnologie Werkstoff-, Material- und Nanowissenschaft über hervorragende Rahmenbedingungen und hoch motivierte Wissenschaftler an Hochschulen und Forschungseinrichtungen, die in dieser Spezialisierung weltweit ihresgleichen suchen“, erklärt dazu Staatsministerin Dr. Stange. „Beinahe alle Materialklassen von Metallen, Polymeren, Keramiken bis hin zu Verbund- und Naturwerkstoffen werden auf international hohem Niveau bearbeitet. Dabei greifen Grundlagen- und Angewandte Forschung in zahlreichen Feldern eng ineinander und bilden geschlossene Entwicklungsketten bis zu einem Transfer in die Wirtschaft – regional, national und international.“

Der Prorektor für Forschung der TU Dresden, Prof. Gerhard Rödel, ergänzt: „Mit dem Carbonfaser-Technikum ist im Research Center Carbon Fibers eine weltweit einzigartige Anlage entstanden, die völlig neue Möglichkeiten eröffnet. Es geht darum, Fasern mit einem möglichst hohen Individualisierungsgrad zu designen – je nach Bedarf und Einsatzbereich.“

Auf der derzeit installierten, einzigartigen Anlage erforschen Wissenschaftler des RCCF unter Reinraum-Bedingungen die Grundlagen für maßgeschneiderte Kohlenstofffasern und erschließen deren hohes Innovationspotential. Dabei greifen die Forscher auf einzelne Anlagenmodule zur Stabilisierung und Carbonisierung mit industrienahem Ofendesign und individuell einstellbaren Parameterkombinationen zurück. Durch den außerordentlichen Reinheitsgrad sind die Carbonfasern für die Anforderungen der Luft-/Raumfahrt- und der Automobilindustrie maßgeschneidert.

„Die Carbonfaser ist der Stahl des 21. Jahrhunderts“, führt Prof. Hubert Jäger, Sprecher des Instituts für Leichtbau und Kunststofftechnik (ILK), aus. „Ganze Branchen erfinden sich derzeit durch diesen Werkstoff neu und erreichen mit ihren Produkten nie gedachte Dimensionen. Das Problem ist jedoch die Verfügbarkeit. Wir werden mit dem Carbonfaser-Technikum einen Beitrag dazu leisten, dass aus Sachsen heraus dieser Werkstoff nicht nur leichter verfügbar, sondern auch besser und maßgeschneidert einsetzbar wird für Anwendungen in der Luft- und Raumfahrt, Fahrzeugbau, Architektur und Hochleistungselektronik.“

„Mit der Inbetriebnahme des Carbonfaser-Technikums unter Reinraumbedingungen am RCCF gelingt es uns, die Prozesskette zur Fertigung maßgeschneiderter Kohlenstofffasern signifikant zu erweitern. Die notwendigen Maschinentechniken des ITM einschließlich der bereits gewonnenen Erfahrungen bei Prozessoptimierungen zur Herstellung von Precursorfasern, dem Ausgangsmaterial für die neuen Stabilisierungs- und Carbonisierungslinien, stehen in künftigen Forschungsvorhaben den Wissenschaftlern des RCCF zur Verfügung. Somit geben wir am exzellenten Forschungsstandort Dresden die Initialzündung für die weiterführende Grundlagen- und anwendungsorientierte Forschung auf dem Gebiet der Kohlenstofffasern“, ergänzt Prof. Chokri Cherif, Direktor des ITM und Inhaber der Professur für Textiltechnik.

Das Carbonfaser-Technikum umfasst einen mehr als 300 m² großen Reinraum der Klasse ISO 8. Neben den beiden auf etwa 30 Metern aufgestellten Stabilisierungs- und Carbonisierungslinien sind weitere Flächen für künftige Erweiterungen der Gesamtanlage vorgesehen, zum Beispiel ein weiterer Hochtemperaturofen, in dem Carbonfasern bis zu Temperaturen über 2000°C graphitierbar sind oder unikale Beschichtungsanlagen zur Oberflächenaktivierung.

Die RCCF-Wissenschaftler ergründen die Wechselwirkungen zwischen Prozessparametern, Faserstruktur und weiteren mechanischen, thermischen und elektrischen Eigenschaften bei der Herstellung von Carbonfasern, um die Fähigkeiten des Hightech-Werkstoffes weiter zu steigern. Zusätzlich nehmen die Forscher die Entwicklung multifunktionaler Fasern mit neuartigen Eigenschaftsprofilen wie hohe Leitfähigkeit bei hoher Festigkeit oder ausgeprägter Verformbarkeit sowie die Nutzung erneuerbarer Ausgangsstoffe in den Fokus ihrer Arbeiten.

Ein weiterer Schwerpunkt der RCCF-Aktivitäten ist die tiefgreifende studentische Ausbildung im Bereich der Carbonfaser-Herstellung. Den Studierenden werden dabei fundierte Kenntnisse in Herstellung und Weiterverarbeitung von Carbonfasern vermittelt, damit sie in diesem Bereich der Zukunftstechnologien dem sächsischen und deutschen Arbeitsmarkt zur Verfügung stehen. Etwa 15 Studierende werden pro Jahr in Forschungsbereiche wie die Prozessführung, -modellierung und -überwachung sowie die Entwicklung, Fertigung und Charakterisierung neuer Carbonfasern und Verbundwerkstoffe einbezogen.

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.
