• 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.

• Oerlikon presents its expanded nonwovens product portfolio at the IDEA 2019 in Miami

Neumünster – Oerlikon presents its complete nonwoven plant portfolio for the production of airlaid, meltblown, spunbonded and hybrid materials at this year’s IDEA in Miami from 25–28 March. The focus of its presentation will be on solutions for hygiene, medical and other disposable nonwovens. Visitors to this year’s IDEA can inform themselves on the wide range of products at Oerlikon’s exhibition stand (no. 1724).

Two strong partnerships for disposable nonwovens

While two years ago the Nonwoven business unit of the Oerlikon Manmade Fibers segment focused almost exclusively on solutions for technical applications, the company has now expanded its product portfolio to include solutions for disposable nonwovens by establishing strong partnerships.

Oerlikon & Teknoweb Materials – two strong partners for the nonwoven industry

As early as spring 2017, Oerlikon Manmade Fibers' Nonwoven business unit had entered into a strategic partnership with the Italian company Teknoweb Materials. Teknoweb Materials is an established technology supplier in the field of wipes and other disposable nonwovens. With its LEVRA technology, the company has its own patented, particularly efficient manufacturing process for wipes. It also has extensive process know-how on the making and further processing of these nonwoven materials. The Nonwoven business unit of Oerlikon’s Manmade Fibers segment completes this partnership with its well-established machine and plant solutions. Teknoweb Materials will also be represented at IDEA at the Oerlikon exhibition stand (no. 1724).

Cooperation with Shaoyang Textile Machinery

For spunmelt systems solutions for hygiene and medical applications, Oerlikon has been in cooperation with the Chinese machine and plant manufacturer Shaoyang Textile Machinery since Autumn of last year. The goal of these cooperation partners is to advance the international marketing of spunmelt plants outside of China. Oerlikon Manmade Fibers’ Nonwoven business unit contributes its plant engineering know-how and is responsible for product and process guarantees. Oerlikon also assumes the overall project responsibility as well as world-wide customer service outside of China. In return, Shaoyang, with its headquarters in the city of the same name in the Hunan province, supplies the plant technologies.The advantage for the customer: competitive solutions at an attractive price level with comparatively low investments.

• 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.

At Heimtextil, which is to be held in Frankfurt from 9 to 12 January 2018, Trevira GmbH will be represented together with some important Trevira CS clients in Hall 4.2 at a 1,305 m2 booth.
The core of this joint booth will be a Trevira exhibition. Participating clients will present their latest Trevira CS collections for home textiles and commercially used textiles at individual stands around this core exhibit. The joint stand is located in close proximity to the new exhibition “Interior. Architecture. Hospitality. EXPO” of Messe Frankfurt.
“We are delighted to be able to make a significant contribution to the new thematic focus of Hall 4.2 with our trade fair concept for next year. It enables us to offer a platform to our clients allowing them to reach important decision-makers. In

addition, visitors to the trade fair will appreciate being able to find such a large number of Trevira CS novelties and collections in a one-stop-shop,” says Anke Vollenbröker, Head of Marketing at Trevira GmbH.
Trevira CEO Klaus Holz is pleased that the idea of a joint stand has been so well received by their clients. “The high level of demand shows that our concept of a comprehensive partnership with our clients pays off. Our long-standing clients appreciate that we not only offer them high quality and sustainably produced fibres and yarns, but that we also support them with our technical expertise and in marketing their Trevira fabrics.”
