• 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.

• 8^th edition to be held as the “Fair & Convention for Hightech Textiles” at the Carlowitz Congresscenter Chemnitz for the first time on 9 – 10 June 2020 – Textile themes from the LiMA exhibition for lightweight design are being integrated in the new format

 
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.

CHOMARAT, the expert in composites reinforcements, is the partner of BABOLAT with its multiaxial carbon, C-PLY™ Hexagonal. Indeed, the specialist racket sports goods manufacturer is launching the new version of the BABOLAT’s Pure Aero. A combination of ultra-modern design and high performance, this tennis racket for champions has made an appearance on the courts of the Rolex Paris Masters. “We are very proud to be chosen by BABOLAT. Our new carbon reinforcement, added to the heart of the racket, enables better control and makes each shot more precise and stable,” says Pascal JOUBERT DES OUCHES, Sports Equipment Market Director at CHOMARAT.

C-PLYTM HEXAGONAL, THE PERFECT ALLIANCE OF PERFORMANCE & DESIGN
The addition of C-PLY™, CHOMARAT’s multiaxial carbon reinforcement, to the core of the BABOLAT’s Pure Aero has increased the racket’s stability while enhancing its performance. The specificity of the reinforcement lies in its stitching thread. “This unique thread brings out the color of the resin pigments because it has been designed to remain visible after its impregnation. It also contributes to extra reinforcement and an exceptional design!” concludes Pascal JOUBERT DES OUCHES.

To receive an award at PERFORMANCE DAYS is the ultimate industry recognition. In selecting the winners of the (ECO) PERFORMANCE AWARDS, the jury handles with total integrity with no outside influence and is absolutely free in making its decisions. This season there are so many outstanding innovations at the exhibition that two awards are announced!

WATER – OUR RESPONSIBILITY, the current FOCUS TOPIC for the next trade fair on November 28-29th, seems to have spurred the PERFORMANCE DAYS exhibitors to peak performances. The trade fair has highlighted innovations every season for the past ten years, but seldom have there been so many outstanding new developments. So many in fact, that two awards are to be presented: the ECO PERFORMANCE AWARD for best sustainable development, and the PERFORMANCE AWARD for a new functional highlight.  

And the winner of the ECO PERFORMANCE AWARD is:
The jury is highly enthusiastic about the nomination of the ECO PERFORMANCE AWARD winner and described the award-winning fabric as the best ecological solution currently available on the market. This extraordinary laminate from Jou Jou Fish combines various sustainable technologies. Article "JYRNP0002 307" consists of 100% recycled nylon and is designed with a micro-porous membrane (functional performance 15K/10K) that is produced without solvents. This saves a lot of water, plus the fabric is made from pre-dyed fibres (solution-dyeing) and the DWR coating is applied using a dry-finish treatment. The only thing that could improve it: as the polyamide is currently produced from postindustrial waste products, it would be nice to have option of using post-consumer polyamides in the future.

And the winner of the PERFORMANCE AWARD is:
The PERFORMANCE AWARD recognizes another pioneering development. Never before has there been such a fine, yet still tear resistant, highly functional fabric. The winner is article "DPQ 1092 DWR" from Green Threads and with only 17g/m² an absolute lightweight. Particularly fine nylon yarns are used (7d and 4d); a 4d yarn has never before been used in functional fabrics. This plus the extremely good tear resistance clinched it for the jury. Another plus for the winner: this lightweight fabric can achieve with just 17 g comparable performance values to a 50g fabric; thereby, not only is the weight significantly reduced, but also the amount of raw materials and energy consumed in production. This is also a factor that protects the environment when the garment is disposed at the end of its useful life.

What does the furniture market look like and what potential composites offer for the furniture of today and tomorrow? The AZL is investigating this question together with companies from the composite and furniture industry. The result will be an overview of the current market and the materials used to date as well as an outlook on future mass applications for fiber-reinforced plastics (FRP). The study is open to interested companies and starts with a kick-off meeting at Composites Europe in Stuttgart on November 7th, 2018.

Furniture, its design and function have undergone major changes in recent decades: From robust lifelong companions to trend-setting models, from handmade one-of-a-kind pieces to mass products, from storage objects to multi-functional and “smart” all-rounders. This goes along with an increased diversity in terms of design and the materials used – and high potential for composites that offer additional design freedom and exceptional mechanical properties at low weight.

Study provides overview of furniture market and unique selling points of composites
In order to systematically identify the potential of fiber-reinforced composites and to use them in future furniture applications, the AZL is starting a study together with companies from the furniture and composite industry. Within four and a half months the market for furniture will be segmented, design and technology trends will be identified and the technical requirements for furniture and furniture components will be broken down to identify applications with high potential for composites. The overall goal is to understand the selection process and needs of the furniture designer in order to bring composites to the market as a targeted alternative to conventional materials.

Virginia Bozsak, Technical Manager Composites at ARKEMA Innovative Chemistry is participating in the study: “The ever-growing population number requires environmentally friendly material and a solution for the end of life treatment to recollect and reuse materials. For fast changing markets such as the furniture market, these materials also need to offer an enormous freedom of design. Arkema already answers this demand with the only liquid thermoplastic resin Elium® used as a thermoset resin to produce composite structural or aesthetical parts. With the joint study, we aim to identify specific applications in the furniture market to make use of material which is not limiting creativity or design specifications but rather enabling the future to be revolutionized.”

Because aircraft engine noise contributes to environmental noise around airports and populated cities, the aerospace industry has been working on new aircraft designs that will emit less noise so they can meet the ever-increasing requirements imposed on the industry to reduce noise pollution. Shielding and absorbing aircraft engine noise at the source represents one of the most effective ways to address this issue.

Hexcel, a global leader in advanced composite technology, has been at the forefront of acoustic technology development with its Acousti-Cap® broadband sound-reducing honeycomb, which enables engine designers to reduce the noise from takeoffs and landings yet without adding significant weight to the aircraft.
 
“Hexcel has continued investing in the evolution of Acousti-Cap® product technology to improve performance and reduce cost,” said Imad Atallah, Group Product Manager for Honeycomb at Hexcel. “Collaboration with industry leaders, including NASA and Boeing, has been key to that development,” he added.
 
The 2DOF (Two Degrees of Freedom) honeycomb core acoustic liner was introduced in 2008 and was subsequently adopted and installed on the Boeing 787 Dreamliner inlet, the Boeing 747-8 inlet and transcowl, and more recently on the Boeing 737 MAX inlet. This success enabled continued technology development and evolution in MDOF (Multi-Degrees of Freedom) where the acoustic septum is inserted in the honeycomb cell at different heights, as well as having two septums in honeycomb chambers. This type of technology allows for improved acoustic attenuation at a broader frequency range, as well as increased absorption.
 
“Hexcel’s Acousti-Cap® technology has shown great performance benefits over competing technologies from the beginning” said Clark Smith, Director of Technology -- Core Products at Hexcel. “We have continued to improve the technology through taking advantage of the single cell treatment concept, by adding capability that the industry was looking for,” he added.   
 
Hexcel’s latest Acousti-Cap® technology was recently tested in a joint NASA-Boeing flight test on a B737 MAX test platform, and the results beat expectations as reported by Aviation Week. Collaboration between Hexcel and NASA over several years on the development of MDOF technology led to the successful test results on this latest flight test.
 
The ability to attenuate a broader noise frequency range and increase acoustic absorption with the Hexcel liner has allowed an optimized design of the overall inlet that reduces drag and improves noise attenuation. Hexcel continues to invest in acoustic liner technology and is proud of the positive results of this NASA-Boeing flight test.

Aachen researchers have developed the adaptive textile facade green.fACade, which was presented on 2^nd August 2018 in the Aachen Faculty of Architecture of RWTH Aachen University, Germany. green.fACade is installed in front of a building like a second skin and can permanently reduce nitrogen oxide pollution in cities.

The researchers achieve the reduction of harmful nitrogen oxides (NO and NO2) by coating the facade with titanium dioxide. Titanium dioxide acts as a photo catalyst and enables the oxidation of nitrogen oxides to form washable nitrate (NO3-). Since the facade is also greened, it contributes to the conversion of carbon dioxide into oxygen by photosynthesis. In addition, a green facade creates an optical resting point in the cityscape and reduces urban heat through evaporation cooling. The enclosed pictures demonstrate how the introduction of green.fACade can have an effect. Picture 1 shows the Aachen Central Bus Station after, picture 2 before the possible introduction of green.fACade.

green.fACade is part of the innovative research project "adaptive textile facades", which uses the special properties of textiles. Thanks to its design, textiles can let sunlight and air through, thus contributing to a modern, aesthetic building design. A new feature of the research project is that further elements such as the titanium oxide coating or sun protection elements are integrated into the textile facade and placed in front of the existing building facade. The adaptive textile facade acts independently and thus reduces energy consumption through the positive climatic effects on the building facade.

"Adaptive Textile Facade" is part of a current research series with the aim of developing innovative facade constructions that are climate-neutral and increase the comfort of local residents. The research team consists of the three RWTH fields of architecture (Faculty of Architecture, PhD student architect M.Sc. Jan Serode), medicine (University Hospital RWTH Aachen, Clinic for Ophthalmology, Prof. Dr Walter) and textile technology (Institut für Textiltechnik, Prof. Dr Gries) and was able to contribute its expertise in the best possible way.

This summer the research team was supported for the first time by the Munich architectural office Auer Weber, represented by managing director Philipp Auer: "For us architects, developments in the field of textile outer shells are a special challenge. Here, highly developed textile materials and processing methods are combined with the lightness and grace of fabrics. Adaptive textile facade elements will increasingly turn the "building shell" into a "building skin", a system that not only offers weather, heat and sun protection, but is in constant intelligent exchange with its environment".

The great importance of these topics for the public was documented by the presence of Kirsten Roßels, representative of the Department of Economics, Science and Europe of the city of Aachen.  Ms Roßels explains: "As the city of Aachen, we are delighted with the innovative and future-oriented project ideas that are being developed at Aachen University, such as the adaptive textile facade. These developments underline the importance of Aachen as a city of science and I would appreciate it if these and other technologies could also become visible in Aachen in the future".

Prof. Dr Gries from the Institut für Textiltechnik sums up: "As textile researchers, we see a great opportunity to develop concrete solutions for our urban living spaces together with renowned experts from other disciplines. I'm sure we can make the urban climate more pleasant and reduce pollution."
