From the Sector

• Looking to the future – Frankfurt Fashion Week is positioning itself with a consistently sustainable agenda and propelling the transformation of a modern, resource-efficient fashion industry.

The Conscious Fashion Campaign (CFC), working in collaboration with the United Nations Office for Partnerships (UNOP), will be the presenting partner and the Sustainable Development Goals (SDGs) will be a prerequisite for all exhibitors by 2023. And the Frankfurt Fashion SDG Summit by CFC is set to become the leading international conference for sustainability in the fashion world. The future of fashion has begun – and its key players will be coming together in Frankfurt am Main from 5-9 July 2021.
 
Frankfurt am Main, 2 December 2020. Joining forces to improve the fashion industry: Frankfurt Fashion Week is positioning itself as the host of the future of fashion and actively driving forward the transformation towards a future-oriented, more sustainable fashion and textile industry. All decision-makers looking to instigate this change will be coming together in Frankfurt am Main from 5-9 July 2021. The initiators of Frankfurt Fashion Week – Messe Frankfurt and the Premium Group – have achieved a real coup: Conscious Fashion Campaign, working in collaboration with the United Nations Office for Partnerships, will be the presenting partner. Messe Frankfurt will build on its collaboration with the United Nations Office for Partnerships and establish Frankfurt Fashion week as the platform on which to advance the Sustainable Development Goals and help guide the fashion industry into the 'Decade of Action'.
 
“Frankfurt will play host to the whole world. We are seeing a very positive response indeed,” confirmed Peter Feldmann, Senior Mayor of the City of Frankfurt am Main, at today’s digital press conference, before going on to say: “The fact that the initiators are able to rethink the concept of a Fashion Week in such a way is extremely impressive and proves that the fashion industry is correctly interpreting the signs of the present and future. The time has come for value creation and values to be reconciled. Consistent alignment with the Sustainable Development Goals is an important step in this direction.”
 
“Frankfurt Fashion Week aims to play a crucial role in finding solutions for macrosocial challenges and supporting the goals of international politics such as the European Green Deal. The fashion and textile industries are also expected to be climate-neutral by 2050. If we want to achieve this, we all need to pull together. Frankfurt Fashion Week is inviting all initiators and supporters of sustainable concepts and congresses or shows dedicated to sustainability to meet in Frankfurt, partake in discussions and make tangible decisions for the greater good. We will connect the most relevant players and pave the way for a future-proof fashion and textile industry,” says Detlef Braun, CEO of Messe Frankfurt.
 
“Given its global reach, the fashion industry is uniquely positioned to collaborate and engage on the Sustainable Development Goals, in particular on climate action and responsible production and consumption,” said Annemarie Hou, Acting Executive Director of the United Nations Office for Partnerships. “Frankfurt Fashion Week and the Summit will serve as an important platform for education and engagement of the fashion and textile industry in the Decade of Action,” emphasised Ms Hou.
 
The aim of Frankfurt Fashion Week is for all exhibitors, participants and partners to align with the Sustainable Development Goals by 2023. The SDGs will also be incorporated into all formats of Frankfurt Fashion Week. This will help to make the UN’s sustainability goals visible and tangible for the Fashion Week audience, therefore bringing its claim, goals and specific proposals for implementation to an international opinion-forming fashion and lifestyle community. During a one-day Frankfurt Fashion SDG Summit presented by Conscious Fashion Campaign, topics like gender equality, clean water, climate protection, social justice and their significance for a forward-looking fashion industry will be examined in greater depth. Another point on the sustainability agenda: Frankfurt Fashion Week is launching a Sustainability Award for outstanding, innovative, sustainable design, alongside other categories with a global appeal for the fashion and textile industry.
 
"We are committed to setting the wheels of transformation in motion. Not only does the overall mindset have to fundamentally change; the entire industry also needs to have the courage to be transparent and honest. It’s important to see values and value creation as opportunities rather than contentious. We are doing what we do best: connecting the relevant players at all levels. With its ecosystem, Frankfurt Fashion Week will become the enabler. We are creating a platform that will orchestrate industry-wide change. With this as our inspiration, we are also developing our tradeshow formats from a ‘marketplace of products’ to a ‘marketplace of purpose and ideas’,” explains Anita Tillmann, Managing Partner of the Premium Group.
 
A new start in Frankfurt: In summer 2021 the entire fashion industry will be coming to the metropolis on the Main river to inform themselves, be inspired, discuss, negotiate and celebrate. “There’s a huge need to finally meet in person again, to exchange ideas and be inspired. At the same time, digital tools and formats have become an integral part of the fashion industry,” says Markus Frank, Head of the City of Frankfurt’s Department of Economic Affairs and therefore also responsible for its creative industry. “To implement such a future-oriented, all-encompassing overall concept, Frankfurt’s business and creative scenes offer an almost unique concentration of different expertise with its internationally networked agencies, universities and museums. The city’s multifaceted, high-end club, bar and restaurant scene, diverse hotel industry and internationally renowned retail landscape will become the stage for this. This network will be a key factor in the successful implementation of Frankfurt Fashion Week and the way in which it will expand into the public space as a cultural and social happening.”
 
A number of major publishing houses are also showing their commitment to the new Fashion Week in Frankfurt with conferences, events and awards: Textilwirtschaft, the leading professional fashion journal by the Deutscher Fachverlag publishing house, is moving its traditional meeting of the industry’s top decision-makers – the TW Forum, the presentation of the renowned Forum Award, as well as its subsequent conference – from Heidelberg to Frankfurt’s Palmengarten botanical gardens, and will therefore be kicking off Frankfurt Fashion Week on Sunday evening and Monday morning. The Frankfurter Allgemeine Zeitung will be hosting its traditional fashion party for the first time in Frankfurt and publishing a special edition of its FAZ Magazin on Frankfurt Fashion Week. And the ZEIT publishing group is holding its ‘UNLOCK Style by ZEITmagazin’ conference, which was established in 2014, and the ZEITmagazin Fashion Week party in Frankfurt for the first time and will dedicate the whole new issue of ZEITmagazin Frankfurt to Frankfurt Fashion Week. Condé Nast will also be involved in next summer’s Frankfurt Fashion Week with an exclusive event by GQ. And the Burda publishing house will also be represented with various event formats from its lifestyle and fashion brands.There will also be talks with SHINE  Conventions, the organiser of GLOW, about what a mutual collaboration could look like.
 
Frankfurt Fashion Week is also delighted to have the Fashion Council Germany (FCG) on board.  The FCG is theinstitution when it comes to German fashion design. It promotes designers, is committed to gaining more political relevance and strengthens the international visibility and awareness of German fashion. At Frankfurt Fashion Week, the FCG will contribute selected formats, such as its already established Fireside Chat, and a future-oriented accelerator format to support German designers.
 
“What really impresses me about Fashion Week is the whole networking aspect: the creative industries will meet the financial world and sustainability is the common denominator. The Green Finance Cluster is another project that we could link with Frankfurt Fashion Week in the future. This will provide new inspiration in the fashion industry, which will certainly extend way beyond its own horizon of Frankfurt and Hesse. After a very difficult year for the trade fair industry, the concept is an encouraging breath of fresh air,” sums up Tarek Al-Wazir, Hesse’s Minister of Economics, Energy, Transport and Regional Development and Deputy Minister-President of the state of Hessen.

• Collaboration Between DuPont™ Sorona® and Sateri’s EcoCosy®

DuPont™ Sorona® and Sateri’s EcoCosy® have together developed a new fabric called StretchCosy™. The fabric uses a blend of Sorona®, a partially plant-based fibre, and Sateri’s ultra-comfortable and near weightless EcoCosy® fibres to achieve a soft material that is highly stretchable, shape-retaining and, most importantly, sustainably sourced.

StretchCosy™ combines the mechanical stretch of Sorona® stretch fibres, which gives it excellent stretch and long-lasting, consistent recovery, with the soft, cotton-like breathability and smooth silk-like texture of EcoCosy® for an unparalleled fabric that is high-performing and well-suited for fashion and sportswear.

Created in 2019, StretchCosy™ is a fabric breakthrough that made it possible for natural plant-based fibres to be more extensively used in various applications, e.g. t-shirts, shirting, bottoms, jackets, dresses, hoodies and underwear. Previously, cellulosic fibres were rarely found in sportswear, due to concerns such as pilling. The combination of Sorona® and EcoCosy® in StretchCosy™ has eliminated this concern, hinting at the future of activewear where performance combined with sustainability will be the norm.

STAMFORD – German ultralight aircraft specialist Flight Design has chosen Hexcel as its key supplier adopting low-temperature curing prepreg into its aircraft production. Hexcel’s HexPly® M79 Carbon Fiber prepregs deliver a more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Design and then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype. As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70˚C for eight hours or 80˚C for four hours, reducing tooling costs and increasing build rates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective of laminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components. The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”

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.

imogo is a new Swedish company formed by a team with long experience in textile processing technology. It is now boldly aiming to change the face of the textile manufacturing industry with its new Dye-Max spray dyeing technology, to be introduced to the market at ITMA 2019 in Barcelona.

While still at the prototype stage, and with a first full-scale line currently under construction and due to be demonstrated this Autumn before delivery, the DyeMax nevertheless promises to slash the use of fresh water, waste water, energy and chemicals by as much as 90% compared to conventional jet dyeing systems.

Spray cassettes
Its application unit consists of a closed chamber containing a series of spray cassettes with precision nozzles for accurate and consistent coverage, in combination with the patented imogo pro speed valve that controls the volume to be applied. The chamber is equipped with an exhaust system and droplet separator to ensure that the environment around the unit is free from particles.

“The spray cassettes are a key part in the Dye-Max line,” explains Imogo’s founding partner Per Stenflo. “There is one set of spray cassettes for each of the three separate dye dispersion feed lines and they can be easily exchanged without the need for tools in less than a minute. This allows for extremely fast changeovers between different colours without the need for cleaning. And because the spray cassettes are removable, all maintenance can be performed off line. 
After applying the dye dispersion the fabric is rolled onto a shaft and moved to the autoclave for deep dye fixation via heat and pressure.”

The savings in treatment water the Dye-Max achieves are due to the extremely low liquor ratio of 0.5 litres per kilo of fabric Stenflo adds. 

“At the same time, the low liquor ratio and the spray process require considerably less auxiliary chemistry to start with, and all of it is used in the process, which also greatly reduces the production of waste water, with only 20 litres being required for wash at changeovers. The low liquid content in the fabric meanwhile minimises the energy needed for fixation.”

The Dye-Max has a working speed of up to 50m/min with the practical speed determined by the fabric weight and application volume. 
 

Albstadt-based circular knitting machine manufacturer Mayer & Cie. (MCT) is exhibiting at this year’s leading textile and garment technology trade fair ITMA with the slogan “Stay a winner. With Mayer & Cie.” The focus of the company’s presentation will be on sport. Sportswear, active leisurewear and sports shoes are increasingly made of circular knitted fabrics and the long-established German firm has the right machines to cater for this trend. Mayer & Cie. is also going for the improved customer experiences that consistent digitization makes possible.

For years global demand for circular knitted goods has increased continuously. An important growth driver is the sportswear and sports fashion sector, including sports shoes. According to Euromonitor the market segment grew by about seven per cent per year between 2013 and 2017. By 2017 Euromonitor estimated its total market value to be around USD 78 billion. Lightweight synthetic fibres, new patterns and attractive functionalities are the key requirements in this area.

Mayer & Cie. can already fulfil many requirements with a portfolio of machines considered to be the largest in the industry. Lightweight mesh structures, often requested for running shirts, are a speciality of the IG 3.2 QCe interlock machine, for example. Jacquard machines from the OVJA family, in contrast, are suitable for the manufacture of shoe uppers. Compared with the conventional methods flat knitting and warp knitting, circular knitting scores points for productivity and significantly shorter set-up times.

Series production of the Spinit 3.0 E spinning and knitting machine has been under way since the end of 2018. It combines two previously separate processes – spinning and knitting – in one machine. That saves time, space and energy compared with conventional manufacturing processes. Mayer & Cie. has already won several awards for this approach, the latest being the Innovation Prize for the Climate and the Environment (IKU) that the Federal Environment Ministry and the Confederation of German Industry (BDI) award every other year. The company is presenting at ITMA its further developments of this machine.

Along with machine development Mayer & Cie. has set itself another target for ITMA and thereafter: to improve the customer experience, a task of which Sebastian Mayer is in charge. His responsibilities at Mayer & Cie. are for corporate development and digitization. Digitization of the company’s extensive customer and machinery know-how is currently under way. Customers will be able to see and test the initial results at ITMA. Available for testing will be the new Web shop, linked with an analogue model of the high-bay warehouse in Albstadt-Tailfingen, and machine maintenance by means of HoloLens.

• 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.
