• Series order for a total of 500 units
• First SGL Carbon component project for manned autonomous aviation

SGL Carbon will begin serial production of landing gear made from braided carbon fiber material early this year. The landing skids will be installed in around 500 air taxis worldwide over the next two years.

The air taxis will be powered by several electric motors. To optimize the range of the taxis, every single gram counts. Measuring about two meters in length and 1.5 meters in width, the ultra-light landing skid will weigh less than three kilograms, making it about 15 percent lighter than a similar component made from aluminum. This increases the potential flight time capacity of the air taxi which is a key differentiator for the air taxi operator.

“With with our landing gear we help to shape this very new, promising application of manned, autonomous civil aviation. This involvement also demonstrates our wide range of services. From engineering, to prototype manufacture, to serial production with our own materials – all of our competences along the entire value chain made a contribution to the project ,” emphasizes Dr. Andreas Erber, Head of the Aerospace segment of the Composites – Fibers & Materials business unit at SGL Carbon.

The landing gear was developed in close collaboration between customer experts and specialists from SGL Carbon. The carbon fibers for the component are produced at the SGL Carbon plant in Muir of Ord, Scotland. The final part is being manufactured at the SGL Carbon site in Innkreis, Austria.

• Glass fiber textiles for helicopter type H145
• First ever material supply for primary structural components in the aerospace segment

Since August of this year, SGL Carbon delivers two special glass fiber textiles, so-called non-crimped fabrics, for the new version of helicopter model H145 from Airbus Helicopters. These materials are used in the new, especially efficient five-blade rotor. Developed in close collaboration with Airbus Helicopters, the material has been qualified for the application for the next years to come.  

Thanks to their unidirectional fiber orientation, the fabrics are extremely resistant, providing optimal support for the new geometry of the especially long H145 rotor blades. The fabrics are manufactured at the SGL Carbon site in Willich near Düsseldorf in a multi-stage process and delivered to Airbus Helicopters in Paris.  

“The order emphasizes our growing presence in the aerospace business. With the fabrics for Airbus Helicopters, we have realized, qualified, and started serial production for a material concept for primary structural components for the first time,” underscores Dr. Andreas Erber, Head of the Aerospace segment in the business unit Composites – Fibers & Materials at SGL Carbon.

The current deliveries are part of a framework contract with Airbus Helicopters, intended to gradually intensify collaboration. Besides the current development of materials for helicopter components, Airbus Helicopters and SGL Carbon have worked together in the area of component material processing for Airbus group aircraft doors for years. In addition, Airbus and SGL Carbon are jointly involved in various associations and research projects in the area of components, such as Carbon Composites e.V.

• Hexcel  at Space Tech Expo, Bremen Hall 5 - Stand B20

STAMFORD, Conn. – Hexcel is exhibiting for the first time at the Space Tech Expo Europe show in Bremen, Germany on November 19-21 to promote its latest technologies and innovations for space applications. More than 3,000 visitors are expected at this major international forum that is dedicated to new and innovative solutions for space business and technology.

Hexcel is improving the way the world’s spacecraft components are manufactured and will feature a number of 3D-printed flight-ready carbon fiber parts manufactured from HexAM® additive manufacturing technology, combining Hexcel’s proprietary high performance PEKK thermoplastics with aerospace grade carbon fiber. HexPEKK® structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts in highly demanding aerospace, satellite and defense applications.

Other Hexcel solutions for space applications that will be presented include carbon fiber, prepregs and honeycomb materials with proven performance for satellite structures and launchers.

Deterioration in market segments Textile Fibers and Industrial Applications in the business unit CFM will be counteracted with various measures; strategic growth markets remain intact

• Continued weakness in the business unit Composites – Fibers & Materials (CFM) in the final quarter of 2019 due to the further weakening in the market segment Textile Fibers as well as the deteriorated economic environment in the market segment Industrial Applications leads to a guidance adjustment for the full year 2019
• Earnings deterioration at CFM triggers an impairment testing; impairment charge will become necessary
• Initial outlook for 2020
• Comprehensive measures initiated to improve earnings of the CFM business unit
• CFM strategic growth markets automotive and aerospace remain intact
• Growth in higher-margin aerospace business to be accelerated

While the preliminary results for the first nine months 2019 remain, overall, within the scope of the full year outlook outlined in the ad-hoc notification of August 14, 2019 (preliminary 9M/2019 recurring EBIT: Group: approx. €54 million, CFM: approx. minus €2 million, GMS: approx. €71 million, Corporate: approx. minus €15 million), continued weakness is becoming apparent for the final quarter 2019 in the reporting segment Composites – Fibers & Materials (CFM). This is due to the further weakening in the market segment Textile Fibers as well as the deteriorated economic environment in the market segment Industrial Applications.

SGL Carbon therefore now expects for the full year 2019 a recurring EBIT in the reporting segment CFM in a negative mid to high single digit million € amount (previous guidance: positive mid-single digit million € amount). This results in a Group recurring EBIT for the full year 2019 in the magnitude of €45 to 50 million (previous guidance: approx. €55 million).

The earnings deterioration at CFM triggers an impairment testing. Based on the preliminary status of the new five-year plan, a non-cash impairment charge of €70 to 80 million is becoming apparent in CFM mainly due to the lower starting point in 2019 as well as the ongoing weakness in the market segments Textile Fibers and Industrial Applications. This impairment charge will be recorded in the third quarter 2019. In recent years acquired assets of the former joint ventures with BMW and Benteler are not affected by this impairment.

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.

Hexcel, Progen and Future Aerospace today celebrated the official opening of their new joint venture laboratory and materials testing facility in Shanghai, China.

Future Aerospace Hexcel Commercial Composite Testing Limited (FAHCCT) will provide China with a world-class aerospace standard materials testing laboratory that provides technical services including support with materials qualification for commercial aircraft programs. Planned activities at the site will include mechanical and chemical testing of composite laminate specimens (including fatigue performance), material qualifications, and provision of support for customer supply chains in China.

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 and Arkema have announced that they will open a joint research and development laboratory in Les Avenières (Isère), France in April.

This follows the companies’ previous announcement in March 2018 that they were forming a strategic alliance to develop thermoplastic composite solutions for the aerospace sector, combining the expertise of Hexcel in carbon fiber and Arkema in PEKK.

The companies’ objective at this new lab is to develop carbon fiber-reinforced thermoplastic prepreg tapes to enable lightweight parts to be produced for future generations of aircraft. These solutions will provide lightweight and cost effective technologies including faster production cycles for customers in the aerospace and the space and defense sectors.

Thanks to Hexcel and Arkema’s close collaboration, an initial industrial pilot line will be installed in the new lab in the coming weeks. The companies expect to start supplying carbon/thermoplastic UD tapes from this pilot line to customers for evaluation beginning in Q3 2019.

• 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.
