From the Sector

Hexcel Corporation has been approved by Boeing to produce HexPEKK™-100 aerospace structures for major commercial aircraft platforms.

After rigorous review of Hexcel’s proprietary poly-ether-ketone-ketone and carbon fiber material formulation, Hexcel’s superior HexPEKK™-100 end-use components – as well as its highly-controlled HexAM™ additive manufacturing process (which uses selective laser sintering) – are now obtainable through Boeing’s Qualified Provider List (QPL). These HexPEKK™ components will be manufactured-to-print for commercial aerospace applications where complexity, weight reduction, and strong mechanical performance are critical.

Hexcel provides high-rate serial part production with reduced lead-time and at a lower cost than traditional intricately machined aluminum or composite structures. HexPEKK™-100 parts meet interior aircraft smoke and toxicity requirements and are ideal for complex components such as optimized brackets, environmental control system ducts, and castings.

STAMFORD, Conn. – At this year's Paris Airshow [Le Bourget, June 17-23] Hexcel will promote a range of carbon fibers and composite materials used to manufacture high-performance weight-saving structures in civil aircraft, engines, helicopters, and space applications.

Visitors to the Hexcel stand will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® carbon fiber reinforcements. HiTape® dry carbon reinforcements were developed for the automated lay-up of preforms and to complement a new generation of HiFlow™ resin systems, producing high-quality aerospace structures using the resin infusion process. The reinforcements incorporate a toughening veil to enhance mechanical properties and meet the structural requirements for aerospace parts. The I-Beam was manufactured using C-RTM (Compression Resin Transfer Molding) and was injected with Hexcel’s RTM6 resin in a process taking less than five minutes.

Hexcel honeycomb saves weight and enhances stiffness in composite structures, and the company provides a range of engineered core solutions that enable highly contoured parts with precision profiling to be produced to exact customer specifications. A sample part made from aluminum FlexCore® that is CNC machined on both sides and formed and stabilized with both peel ply and flyaway layers of stabilization will be on display.

Another honeycomb innovation is Hexcel’s 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.
Another Hexcel technology to benefit aircraft engines is HexShield™ honeycomb which provides high-temperature resistance in 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 reuse of material after a fire.

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.

Another area of expertise that uses HexTow® carbon fiber is additive manufacturing, where Hexcel uses PEKK ultrahigh 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.

Later this year Hexcel will open a joint research and development laboratory in Les Avenières (Isère), France with Arkema to develop carbon fiber-reinforced thermoplastic prepreg tapes for aerospace, space and defense applications. A spool of thermoplastic prepreg tape will be on display on Hexcel’s stand to showcase this cost-effective technology that enables lightweight parts to be produced in faster production cycles for future generations of aircraft.

Hexcel’s stand is located next to Hexcel’s official distributor for aerospace products, Groupe Gazechim Composites. In 2018, Hexcel and Gazechim formed a joint venture, HexCut Services, to provide aerospace and defense customers with customized kitting services that include Hexcel’s innovative carbon fiber prepreg, fabrics and adhesives. Pre-cut kits save customers time and investment, reduce inventory and minimize material losses through scrap reduction.

Hexcel has joined forces with a Lyon-based startup, LAVOISIER COMPOSITES. This company has developed CARBONIUM®, a new generation of material sourced entirely from carbon composite by-products generated by the French aerospace sector.

Hexcel supplies high-performance composite materials for the latest generation of aircraft such as the Airbus A350 XWB (53% composite structure). This has greatly contributed to the reduction of the aircraft's weight, thereby reducing its fuel consumption and carbon footprint. Composites are a significant first step toward tackling environmental and economic challenges, and eco-sourcing of the industry by-products also plays a key role.

CARBONIUM®, which was developed with a process based on three patents pending, reduces overall environmental impact by 40-50%, compared to equivalent products derived from virgin materials. Based on the "climate change" factor, the life cycle assessment carried out with Hexcel revealed that the up-cycling of by-products from the aerospace composites industry leads to a reduction in CO2 emissions of 13kg per kg of CARBONIUM® used.
In its first year of operation, LAVOISIER COMPOSITES has already enjoyed commercial success, including the launch of two top-of-the-range watch models by Swiss luxury watchmaker ULYSSE NARDIN using this new material.

From aircraft fuselages to watchmaking, the composites manufacturing cycle presents opportunities for reducing our impact on the environment.

• 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.

JEC Innovation Awards celebrate the fruitful cooperation between players of the composite community. Over the past 15 years, the JEC Innovation Awards have brought in 1,800 companies worldwide. 177 companies and 433 partners have been rewarded for the excellence of their composite innovations. The JEC Innovation Awards reward composites champions, based on criteria such as partner involvement in the value chain, technicality or commercial applications of innovations.

3D PRINTING, A NEW CATEGORY IN 2019
In 2019, 30 finalists have been selected by an international jury of experts from more than a hundred applications. They compete in 10 categories, among which the new 3D printing one. "The JEC Innovation Awards program is emblematic and recognizes pioneers in composite innovation. 3D printing plays a new role in our industry. The combination of lightweight, resistant materials that allow great design freedom, with a technology that allows complex shapes, is of interest to manufacturers. Many manufacturers have started using it to print automotive parts, aircraft parts, or building walls”, analyses Franck GLOWACZ, Innovation Content Leader at JEC Group. “Due to the very high level of the nominees, the JEC Innovation Awards ceremony should be very rich! ”

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

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

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

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

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

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

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

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

C-PLY^TM,
THE CHOMARAT REINFORCEMENT THAT HAS ALREADY PROVEN ITS WORTH IN THE AEROSPACE INDUSTRY
CHOMARAT has already made a name for itself in the aerospace market with fabrics, tapes and multiaxial carbon reinforcements, particularly its C-PLY™ range. These materials are designed for primary and secondary structures as well as aircraft interior parts. These highly modular materials offer great angle and ply flexibility and open up new opportunities for designing lighter, more efficient and lower cost composite parts. This is a huge advantage in a market with high productivity demands.
This is why C-PLY™ was recently chosen by VX AEROSPACE for their foldaway drone, which can be stowed inside a cylindrical container and deployed from a tactical aircraft. The carbon multiaxial material is used in the construction of the wing, the horizontal stabilizers, the vertical fin and all of the control surfaces. “There is no better material! The extremely thin multiaxial reinforcement is perfect, because strength and stiffness are tailored according to demand. It offers extremely high performance at a reduced cost.” said VX AEROSPACE Chief Engineer Bob SKILLEN.

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.

Rounding off the aircraft engine exhibits is a CTi fan blade for new generation lightweight turbofan engines from Rolls-Royce, manufactured from Hexcel’s HexPly® M91 high toughness and impact-resistant epoxy prepreg. 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.
