• 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 world’s leading exhibition for additive manufacturing takes place in Frankfurt am Main every year
• With 26,919 visitors, Mesago, organiser of Formnext in Frankfurt, reported a new record with numbers up by 25% on the previous year.

This year Perlon was amongst the 632 exhibitors from 32 countries for the first time, which, represented by Pedex GmbH from Wald-Michelbach, was a co-exhibitor on a stand for companies from the German region Hesse (Hessen Trade and Invest GmbH - HTAI). Some visitors were surprised to discover that the world leading manufacturer of synthetic filaments is also active in the 3D printing filament field. That the Perlon Group, known innovation and market leader in many fields of application, with its decades of experience in the development and manufacture of filaments, has entered into the 3D printing market was well received.

The fact we actually entered the market 6 years ago, was only known to a few experts in the field. In this time, Pedex GmbH had been producing a wide range of performance filaments for a well-known German 3D printer manufacturer, who since then has distributed exclusively under its own brand. The decision, to out ourselves as producer and supplier was taken in summer 2018. This new direction has two main aims, firstly to establish ourselves in the market as a manufacturer of Perlon® 3D printing filaments, producing both small batches and high volume on an industrial scale for professional applications, but secondly and most specifically to continue along the path as a toll manufacturing partner with long-term contracts on an industrial scale.

As a partner with universities/institutions and member of various research networks, we are close to the quickly advancing developments in this field, which is why we were really pleased to welcome Dr. Andreas Baar and Dr (Ing) Thomas Neumeyer onto our stand. They are both members of RESOPT3D (Netzwerk für ressourcenoptimierten 3D-Druck), Germany’s strongest user network for 3D technologies.

Together with Conspir3D in Rheinheim and its owner Jan Giebels, who 10 years ago was a co-founder of the company German RepRap, we were able to forge a partnership to distribute Perlon® 3D printing filaments. With his support we could competently advise trade visitors about filaments and 3D printing as a collective proactive team.

Next year, Formnext will take place from 19th to 22nd November 2019 for the first time in exhibition halls 11 and 12 at the Exhibition Centre in Frankfurt am Main. This will be a debut exhibition for the USA which will be exhibiting as first partner country at Formnext. The USA has a long tradition in the field of additive manufacturing and is one of the most important international exhibiting nations.

Twelve companies from eight different countries will receive a JEC Innovation Award at JEC Asia 2018. Asia-Pacific is an innovative region that sets the tone for all other regions of the globe. Once again, the JEC Innovation Awards highlight how composites bring solutions considering the new challenges in terms of efficiency, sustainability and life-cycle analysis.

This year, JEC Group awards innovations in the following categories: aerospace (structural and tooling), automotive, commercial vehicles, e-mobility, marine, railway, sports & leisure, infrastructure & civil engineering, industrial equipment, sustainability and additive manufacturing.

The ceremony will take place on Thursday November 15, 2018 at the COEX Center of Seoul (South Korea). Ida DAUSSY (Seo Hye-na), will host the ceremony in front of officials, manufacturers, scientists and composites professionals.

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.

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.

• Successful acquisition of Austrian plastics recycling company Ecoplast Kunststoffrecycling GmbH

Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers, announces today that it has fully acquired the Austrian plastics recycler Ecoplast Kunststoffrecycling GmbH (“Ecoplast”). Based in Wildon, Austria, Ecoplast processes around 35,000 tonnes of post-consumer plastic waste from households and industrial consumers every year, turning them into high-quality LDPE and HDPE recyclates, primarily but not exclusively for the plastic film market.

The expectation of Borealis is that the recycled PO market will grow substantially by 2021, which is the strategic rationale behind the acquisition. The company has made PO recycling a key element of its overall PO strategy because of its potential to support both growth and sustainability. Borealis has been an industry frontrunner in making polyolefins more circular. In 2014, it began offering high-end compound solutions to the automotive industry, consisting of 25% and 50% post-consumer recycled content. Borealis was also the first virgin PO producer to explore the possibilities of mechanical recycling, by acquiring one of Europe's largest producers of post-consumer polyolefin recyclates - mtm plastics GmbH and mtm compact GmbH – in July 2016. Since then it has continued to invest into the development of technology and new products in the area of circular polyolefins.

“Borealis recognises the increasing need for plastic recycling and sees the Circular Economy as a business opportunity. Borealis already has a long-term collaboration with Ecoplast and this acquisition is the next logical step in building our mechanical recycling capabilities. As an important complement to mtm in Germany, Ecoplast will help us address critical sustainability challenges and become a polyolefin recycling leader. Eventually, we want to use our experience to develop an effective blueprint for the end-of-use phases for plastics that can be applied in other parts of the world,” says Borealis Chief Executive Alfred Stern.

“We are very happy that the transaction with a strong and reliable partner such as Borealis has been successfully concluded and are looking forward to our common future activities on the recycling market. We have located potential synergies in many operative and strategic areas, especially in product quality R&D and future applications of polyethylene-film-recyclates. The combination of Ecoplast and Borealis holds the potential to be groundbreaking for the market,” says Ecoplast’s Managing Director Lukas Intemann.

Trevira, one of the market leaders in polyester yarn manufacture, and the development services company imat-uve have together achieved a milestone in textiles design: the use of 3D flat knitting technology for automotive interiors. In a jointly developed process that unites innovative yarn technologies with cutting-edge connection and finishing techniques, Trevira and imat-uve have found a way of producing anatomically contoured seat covers and trim components for vehicle interiors. Why is this important? The answer lies in the way it's done. Because the technology uses just one knitting process rather than several, manufacturers can reduce their production and materials costs, as it's no longer necessary to cut and assemble the fabrics. But the new invention is not just cost-effective – the flat knitting technique means that it's now possible to personalise design and function to a much greater degree, representing another important step in the direction of on-demand production.

Trevira and imat-uve are the first companies to develop such a sophisticated application of the knitting process for use in vehicles, thanks to imat-uve’s innovative processing and finishing technique which deploys a low-melt yarn specifically developed by Trevira. The collaboration has resulted in a high-performing knitted product which satisfies even the most demanding criteria in terms of quality and comfort. The VDA 230-210 standard velcro test carried out by imat's testing laboratory found that the product was extremely abrasion resistant. The 3D flat knitting technology even means that areas known to be vulnerable, such as the seams on seat covers, can be strengthened in the course of the same single knitting process. Another benefit of the technology is its contribution to sustainable manufacturing. Not only does it work on the zero waste principle, but the knitted fabric itself is manufactured entirely from yarn made from PES recyclates.

Thomas Rademacher, Head of Development at Trevira, explains why the collaboration was so successful. "The development company imat-uve came up with a new breakthrough technology, while here at Trevira, we contributed our own recycled yarns and a new low-melt yarn we've developed based on synthetic fibres, which provides a stabilising effect. Together we have created a highly sought-after, top quality product for automotive interiors. Flat knitting will now be the go-to technology for vehicle interiors – in the future, it will be impossible to imagine life without it."

Hans Peter Schlegelmilch, imat-uve’s CEO, pointed out the especial benefits of the new technology for vehicle manufacturers and their suppliers. "The 3D flat knitting technology doesn't just make it possible to save time and money on production. It also opens up a whole new world of personalisation for end consumers. We are extremely pleased that with Trevira as our partner, we have been able to take this significant step towards the future of automotive interiors."

STAMFORD, February 26, 2018 - at JEC World 2018, taking place in Paris March 6-8, Hexcel will display an array of product innovations for customer applications in aerospace, automotive, wind energy and marine markets.
Hexcel’s banner at the exhibit hall entrance features the Airbus H160 helicopter and A350 XWB aircraft, both with carbon fiber livery to acknowledge the high Hexcel composites content in both programs. Hexcel’s reinforcements, prepregs, adhesives and honeycomb materials were selected for the H160’s composite fuselage structures and main rotor blades, contributing to the lightweight fuel-saving design and performance optimization. Airbus has loaned Hexcel an H160 BLUE EDGE blade to display on the booth.

Among the Aerospace promotions at Hexcel’s booth are carbon-reinforced 3D printed parts, made from Hexcel’s HexAM™ additive manufacturing technology that uses PEKK ultra-high performance polymers. Hexcel acquired this technology from Oxford Performance Materials in December 2017 to provide 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.

Aircraft engines benefit from a number of Hexcel technologies that will be promoted at JEC 2018, 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.
Another honeycomb innovation from Hexcel is Acousti-Cap® broadband noise-reducing honeycomb that 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. An example of this technology will be on display at JEC 2018.

Hexcel supplies HexPly® M91 as slit tape for the automated lay-up of the complex aerodynamic shape, with a constantly changing thickness across the blade length. The blade which is thinner and lighter than titanium fan blades is currently undergoing flight tests.
Hexcel’s HiTape® and HiMax™ dry carbon reinforcements that were developed for the automated lay-up of preforms for resin-infused aerospace structures will be promoted at the show. Two demonstrator parts, one made with HiMax™ and one with HiTape®, were both infused with HexFlow® RTM6 resin to demonstrate the potential benefits of an integrated design for aircraft skins, spars and stiffeners that meets OEM requirements for production rate increases and cost effectiveness.

Hexcel is also introducing its new range of HiFlow™ advanced liquid resins for aerospace structures manufactured by liquid molding technologies. Based on novel proprietary chemistry, the new resin family will enhance the performance of composites and ease processing when combined with HiTape® and HiMax™ dry carbon reinforcements. HiFlow™ HF610 is the first resin in the range.
Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil last October. Hexcel is relaunching the acquired products under the new HexBond™ brand name at JEC World. This fast-growing range of pastes, liquid shim and film adhesives has a wide spectrum of operating temperatures and is in qualification with a large number of aerospace and industrial OEMs.
In the Planet Aerospace area at JEC, Daher and Hexcel will jointly display an aircraft spar manufactured from HexPly® M56 prepreg. Hexcel’s Neil Parker and Daher R&T Director Dominique Bailly will give a joint presentation focusing on the materials used and the benefits for the finished part. The aircraft spar was designed and manufactured by Daher using Hexcel’s HexPly® M56 prepreg, in slit tape format, that was developed for automated deposition and out-of-autoclave curing. The spar was manufactured using only the vacuum bag process and demonstrates very low porosity levels. It is currently undergoing testing and validation through CORAC funding.

Hexcel’s Automotive promotions at JEC World 2018 include a new prepreg for composite leaf springs, HexPly® M901. In contrast to steel leaf springs used for suspension on vans, trucks and SUVs, newer composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. Hexcel’s HexPly® M901 prepreg raises the bar further, reducing mold cure time below 15 minutes, a 50% reduction compared to standard industrial prepregs. HexPly® M901 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. Hexcel’s expertise in manufacturing heavy weight glass UD prepregs, with fiber areal weights of up to 1600gsm, allows the company to offer a highly cost-competitive solution for the rapid manufacture of these safety critical components.

Hexcel is constantly seeking ways to ensure that customers obtain the maximum benefit from composites and has recently acquired state-of-the-art simulation technology that accurately predicts how HiMax™ non-crimp fabrics will drape in a mold. Working in collaboration with Nottingham University Hexcel has created a car seat shell, for which the material selection was optimized using this new drape simulation technology. Visitors to Hexcel’s stand at JEC will see an on-screen demonstration that illustrates how the simulation tool operates, predicting process and performance and ensuring that the optimum fabric architecture is quickly identified, reducing the need for expensive trial programs.
Hexcel’s HexMC®-i 2000 carbon fiber/epoxy molding compound has been successfully used by Audi to manufacture a high-performance engine cross brace. HexMC®-i is a fast curing high-performance molding material, suitable for the series production of complex shaped parts and providing excellent mechanical properties. The Audi cross brace covers the engine, providing torsional stiffness for enhanced drive dynamics.

Hexcel’s product offering for customers in the Marine industry has expanded following the acquisition of Formax in 2016 and Structil in 2017. At JEC World, Hexcel will promote its enhanced portfolio of carbon fibers, prepregs, woven reinforcements and multiaxial fabrics for builders of racing catamarans and luxury yachts.
Marine customers have supplied a number of parts for display to illustrate their expertise in manufacturing composite structures from Hexcel materials. These include part of a Diam 24 yacht mast made by ADH Inotec from Hexcel’s HexPly® M79 fast curing, low temperature cure prepreg. ADH Inotec purchased the prepreg from Composites Distribution, a Hexcel Official Distributor that also supplied HexPly® M9.6 prepreg to Lorima for the Outremer 5X catamaran mast section on display. Part of Lorima’s 42m wing mast for a multihull racing boat made with HexPly® prepreg from Vert-Le-Petit (formerly Structil) will complete the marine display.

Hexcel’s innovations for Wind Energy include Polyspeed® pultruded laminates for load-carrying elements in wind blades. These continuous cross-section profiles, made from a polyurethane matrix reinforced with unidirectional carbon fiber, provide consistently high mechanical properties, including high stiffness, fracture toughness and shear strength, combined with low weight and durability. Visitors to Hexcel’s stand will see a 2m diameter coil of pultruded carbon laminate that contains 255m of material in a single roll. This technology offers an economical way of reinforcing large-scale composite structures such as wind turbine blades. Hexcel will also launch its surface finishing prepreg for wind turbine blades and components. This provides a tough, durable and ready-to-paint blade surface without the use of gel coat and results in faster blade manufacture, saving time in production and reducing material costs. The benefits of the new surfacing prepreg will be demonstrated via a wind blade exhibit that has been given four different treatments across the blade surface. These include a section with gel coat, a section of standard prepreg without gel coat, and a section where a fleece has been added to improve surface quality but still requires preparation before painting due to pin holes. The final section made with new HexPly® XF2P surfacing prepreg has a ready-to-paint surface, straight from the mold, without any requirement for gel coat, fleece or finishing operations.

Hexcel Corporation is proud to announce the unveiling of the third H160 prototype from Airbus Helicopters, featuring a striking carbon-inspired livery that represents the composite materials Hexcel supplies for the helicopter.

This gesture follows Hexcel’s announcement in June that its reinforcements, prepregs, adhesives and honeycomb materials had been selected for the H160’s composite fuselage structures and main rotor blades. The H160 was designed by Airbus Helicopters to create added-value for customers in terms of performance, economic competitiveness, safety and comfort. The use of Hexcel’s composite materials throughout the structure contributes to the lightweight fuel-saving design and performance optimization.
Airbus Helicopters decided to promote the H160 program and its high carbon fiber content in a way that recalls the livery previously used for the A350 XWB. The A350 XWB has a structure that is 53% composites and Hexcel supplies the carbon fiber prepreg for all of the aircraft’s composite primary structures.
The newly unveiled H160 prototype is a fitting tribute to the 40-year partnership between Hexcel and Airbus Helicopters.
