From the Sector

• Composite textiles for modern mobility
• Extremely lightweight, high tensile components by vombaur

In the snow, on a plane, in an electric vehicle or on a bicycle: no matter where and how we are on the road – composite textiles by vombaur ensure that we make good progress. With materials that are both extremely light and extremely reliable.

Lightweight components for modern mobility
Modern mobility relies on high-tech lightweight components Narrow textiles by vombaur are woven from high-performance fibres. On looms that are specially made for particularly demanding composite textiles: the textile company uses special machines to produce high-tech woven tapes with closed selvedges and elasticated UD tubulars that retain their 0° orientation over the entire length of the component – regardless of the diameter. Since they do not exhibit undesired break points caused by seams or welding, they not only have a particularly high bursting strength, they are also extremely reliable and durable.

Challenging applications
"From snowboards to aerospace – the applications for our composite textiles are demanding; the mechanical, chemical and thermal requirements are extreme," explains COO Christoph Schliefer. "As a development partner, we at vombaur are therefore often involved in product development at an early stage. We specify our woven tapes and tubulars individually for each project to suit the specific task at hand."

High quality raw materials, wide variety of geometries
The variety of shapes is virtually unlimited. vombaur manufactures 3D fabrics for composites in individual special shapes from carbon, aramid, glass or hybrids. Curves, edges, tubulars, spiral fabrics – the shape of the 3D fabrics, like the material itself, depends entirely on the task at hand. Powder or non-woven coatings create additional important properties.

Pioneering tech tex
"Developments in the field of modern mobility are happening at a rapid pace," emphasizes Schliefer. "With our composite textiles for extremely lightweight and high tenacity components, we at vombaur are also pushing these developments forward."

The Cetex Institut gGmbH, the thermoPre ENGINEERING GmbH and The FilamentFactory GmbH cooperate in the development, production and marketing of novel hybrid materials. The cooperation agreement signed on October 2, 2020 in Chemnitz takes the collaboration to a new level. "We are pleased to be able to supply the hybrid rovings to the end user not only in an application-specific manner, but also to offer the engineering for subsequent component applications, including the prototyping of the FRP components," says Sebastian Nendel, Managing Director of Cetex.

Patented process for the production of hybrid rovings
In the last 3 years the Cetex Institute has developed a plant technology for the production of hybrid rovings. By means of the patented process, different material combinations can be produced according to customer specifications. Material combinations of reinforcing fibers (glass, basalt, carbon, aramid or high-strength polymer fibers) can be combined with matrix fibers (PP, PET, PA, PPS, PEEK), but also special combinations of different reinforcing fibers or the combination of reinforcing fibers with metal fibers. Advantages of the new hybrid roving are the torsion-free and completely stretched fiber layer and the associated optimal utilization of the properties of the reinforcing fibers, as well as a very good homogeneity, whereby excellent processing can be achieved in later process steps.

Series production as next step
The next goal is clearly defined: Under the agreement, the process is to be jointly developed further by the project partners and transferred to series production. These joint activities form the basis for many years of intensive cooperation in this new field.

• Specialised in dye-sublimation printing, the Italian company has conquered the heights of the high fashion sector with its top-quality printed fabrics.
• With its recent investment in a direct-to-fabric printing line, Digitak is preparing to expand its range of printed products, focusing on fabric differentiation.

Dye sublimation printing of high fashion designs is the beating heart of Digitak, an Italian company specialised in digital textile printing. Operating in the textile district of Lombardy, Italy, the company has established itself among the main suppliers in the world of high fashion and sportswear in just under 15 years.

Making production versatility one of the cornerstones of its philosophy, Digitak has continued to invest in technology, as well as research and development its product portfolio. This forward-thinking approach has enabled the company to guarantee innovative, personalised products with meticulous attention to detail, with the highest – almost obsessive – standards of quality and maximum design flexibility. Over the years, the extensive experience gained by the company’s management in the field of sublimation with traditional and digital techniques, combined with their investment decisions have allowed Digitak to enhance its production performance, gradually implementing higher quality standards and differentiating itself from the competition in the complex and competitive sector of high fashion. An important feat, which has not, however, dampened its enthusiasm and willingness to continue growing and exceeding its goals. The company’s latest investment in a direct-to-fabric digital printing line with pigment ink propels the company into a new and promising production dimension.

Sublimation printing specialists

Since Digitak’s establishment, Filippo Taccani, the founder and current owner of the company, had set himself a clear and ambitious objective: “I wanted to take up the challenge of operating digitally - printing fabrics using this innovative technology to create products on a par with those  I had achieved with traditional sublimation textile printing methods during my previous work experience.”

The purchase of a Mimaki JV4 plotter, one of the first to be installed in Italy, marked the beginning of Digitak’s adventure. “To start the business, I needed a printing system that could operate with dispersed inks to print on polyester and I found the JV4 to be the best option,” explains Taccani. “It was an excellent decision, because I used these plotters to build the company and its success.”

The first Mimaki plotter was in fact followed by a second and a third. When it bought the fifth, the company moved to an industrial unit in Tradate (Varese) – Digitak’s current site – which now houses around fifteen Mimaki JV33 plotters, in addition to three Mimaki TS500-1800 wide-format sublimation printers, and a Mimaki TS300P-1800 high-speed sublimation printer. This Mimaki powered production facility – which is one of the company’s core strengths – was recently expanded with the addition of a Mimaki TX300P-1800B belt-type hybrid printing system, together with a Mimaki TR300-1850C textile coater and a Mimaki Tiger-1800.

“Naturally, over the years, we have also tested printing systems from other suppliers, but we have always returned to Mimaki. With high fashion as our key market, we need to guarantee our customers the highest levels of quality and, to date, we have never found solutions that beat the quality of this Japanese brand’s technology.”

According to Taccani, the difference lies in the “calligraphy” of Mimaki’s machines, that is the line of the ink on the fabric: “Unlike its competitors, Mimaki has focused on the ‘waveforms’, i.e. the electronics associated with the print heads. This attention paid to the way the ink jet is managed from the print head has allowed Mimaki to achieve unparalleled levels of accuracy, an aspect that has given my company a clear competitive edge.”

Moreover, at Digitak, quality comes before quantity: “We prefer to dedicate an extra day to production to guarantee the customer a final product that fully meets requirements and expectations. Mimaki’s technology not only suits this business model bult on top quality, but it crucially enables it.”

Operational and creative flexibility

Digitak currently prints around 2,000 linear metres of fabric per day. Its portfolio ranges from clothing and scarves, to beach and swimwear, with related personalised accessories, to sportswear, with technical properties such as breathability, comfort, resistance to external agents. The company have even added customised outdoor furniture to their offering of diverse and creative products.
The company’s machines operate continuously, 24/7. During the day, the machines are mainly used to develop and produce samples and colour proofs, while the actual production is carried out at night. “Thanks to our technology, we have developed an extraordinary operational flexibility. The fact that we have so many plotters allows us to work on multiple designs at the same time and to launch projects that are also very different from one another,” explains Taccani. “There are also some other crucial factors that have contributed, and continue to contribute, to increasing our production efficiency. The reliability of Mimaki’s solutions and the remote monitoring option offered is key. Once the standard start-up monitoring has been carried out and the machines are found to be printing correctly, we can let them work overnight without an operator. This is a great benefit for people who, like us, manage such a large and diverse fleet of machines.”

Digitak takes the same approach to customer service. Faced with an increasingly demanding market in terms of creativity, precision and completeness of service, the company wants to guarantee flexibility and customisation. “We decided to set up a department dedicated to the pre-press stage, in charge of preparing and checking the files supplied by customers. Seldom do our teams not need to do some editing of the files supplied, even if it’s only to make small changes that are essential for the print document to be as suitable as possible and to achieve the best final result.”

Technologies of the future

With a view to further enhancing production and customer service, Taccani has chosen to take on a new challenge, switching things up with some of the most recent investments.

While maintaining the focus on dye sublimation printing, Taccani has focused on technological diversification by installing a direct-to-fabric digital printing line. This consists of a Mimaki TX300P-1800B printing system with pigment inks and a TR300-1850C coater from Mimaki’s TR series. “The market continues to evolve and now requires even more flexibility regarding both processes and the fabrics supplied. This means that great opportunities exist for a print shop capable of simultaneously producing the same design – with minimal colour adjustment – on different fabrics, guaranteeing similar and accurate results. And this is precisely the path we are taking,” says Taccani. “Why have we opted for Mimaki again? Well, I had an opportunity to try out their new pigment inks and I immediately realised that they are a generation ahead of the other pigments available on the market. The cyan is very clean, the black is deep and there is a very interesting fullness of colour, suitable not only for furnishings, but also for other applications in the clothing sector.”

With its pigment inks, the new direct-to-fabric printing line allows Digitak to explore other related market segments. Thanks to the innovative automatic belt system, the TX300P-1800B guarantees good productivity and high-quality results. A standard of quality that is also boosted by the TR300-1850C fabric pre-treatment system: “This coater is essential for ensuring the best possible preparation of fabrics for printing. In fact, we are able to treat fabrics to make them suitable for the type of print they are intended for, sanitise them for specific applications and, in some cases, even dye them, with excellent quality.”

According to Taccani, another beneficial factor of direct-to-fabric pigment printing technology is the eco-sustainability of the process and its lower environmental impact. “We are proud to be able to offer our customers excellent printing results using little water and printing in ‘green mode’, with both the technologies we have available. I consider them winning technologies for the future, as both dye sublimation printing and direct-to-fabric printing with pigment inks use little water while mainly requiring the use of energy. Therefore, if you use renewable energy, then you’re done.”

Digitak’s other trump card is the Tiger-1800 installed in 2019. With this industrial printing system, the company aims to increase production volumes while maintaining its high-quality standards and further optimising costs. “We are excited to have these promising technologies available to us in-house. We are currently experimenting with these solutions, testing new opportunities and evaluating which paths to take to stay ahead of the game,” concludes Taccani.

Modernized press eases digital printing conversion, signals new era for PCMC and RDP Marathon

In addition to the 380V-s, PCMC continues to develop new technologies and applications for a variety of print markets.

After Mondial. Tech, NAIAS 2019, and eMove 360°, JEC Group will hold the 4th Composites Pavilion at the North American International Auto Show (NAIAS) in Detroit from June 9 to 11, 2020 in a spirit of innovation, business, and networking.

At NAIAS 2020, JEC Group will highlight the latest technologies and solutions allowing the automotive industry to innovate in product design, reduce the environmental impact of emissions and improve production rates thanks to composite materials. For the first time in 2020, the Composites Mobility Summit will simultaneously include the pavilion with a showcase of innovative parts, an extensive conference program, and a composites tour. Composite materials are a key part of the future of the Mobility industry and this Summit will both demonstrate the exciting variety of their applications, and aim to push forward their use in an even more global scope.

Within the Composite Solutions for Mobility pavilion, the displayed parts will highlight the different applications of composites for mobility such as lightweight, design freedom, aesthetics and flexibility, resistance, strength and stiffness, function integration, hybridization, fuel storage, connectivity integration and battery housing.

Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part. The prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

Of the twelve participating denim mills who took part in Habitat 21 – a special Smart Creation showcase at the recent Denim Première Vision exhibition in London – no less than eleven were valued Monforts ‘Denimized’ finishing technology users.

The aim of Habitat 21 was to highlight those companies taking an eco-responsible approach to denim manufacturing via the use of recycled, organic and bio-based fibres, in combination with resource-saving dyeing and finishing technologies. Monforts customers involved in the project were Advance Denim, Berto, Bossa, Calik, Evlox/Tavex, Kilim, Naveena, Orta Anadalou, Rajby Industries, Raymond Uco and Soorty. Their innovations were detailed in a major presentation on trends for the Spring/Summer 2021 season by Manon Mangin of the Première Vision Fashion Team, based on three key themes – Sensation, Hybridisation and Expansion.

Heimtextil will launch the new 2020/2021 trend season with the general theme “WHERE I BELONG”. For the official Heimtextil Trend Preview, Stijlinstituut Amsterdam director Anne Marie Commandeur  introduced the new design themes. The presentation in the run-up to Heimtextil (7-10 January 2020) took place at the Textile Museum’s Textile Lab in Tilburg, the Netherlands on 11 September 2019 and was streamed worldwide.

This season, Stijlinstituut Amsterdam is responsible for the Trend Book content and Trend Space implementation at the upcoming international trade fair for home and contract textiles. Alongside Stijlinstituut Amsterdam, London-based studio FranklinTill and Danish agency SPOTT trends & business contributed to the 20/21 global forecast for perspective-related interior design. Together with the Heimtextil management team, these Trend Council participants gave insights into future styles during a workshop.

At the annual international Trend Council workshop, identity was an ever-present topic: part of a broader discussion on gender and cultural diversity, on tolerance and curiosity. Today, the self-identification process seems more complex than ever. Identities are now formed through experiences that take place simultaneously, on different levels. Locally, nationally, globally, both online and offline. Identity therefore can consist of many different layers. In fact, individuals can all have multilayered identities.

Heimtextil Trends 20/21 Overview:

MAXIMUM GLAM

Pleasure seekers revel in layering theatrical influences and glamorous showtime aesthetics, forging a fantastic marriage between the crafted and digitally rendered. Textiles show a ‘more is more’ attitude through a mash-up of glam, gradients and spectrums, fake fur, pile and fringe, jacquard weaves and fantastic prints. The flashy, kitsch colour range becomes brutally glam thanks to electric sheen, synthetic shimmer, digital glitch and artful blur. A riot of clashes and rebellion.

PURE SPIRITUAL

Idealists seek perfection and purity, restoring equilibrium by connecting with the uber-natural. They embrace technology for good while shifting between realism and mysticism in pursuit of a personal haven. To address a renewed bond with nature, organic matter, raw materials and pure textiles are selected which show nature’s traces, organic structures and irregularities. Shades are created from the earth and cultured by man. An elemental and pure range reflects the source of their existence.

ACTIVE URBAN

Urban dwellers confront the challenges of the fast paced, shape-shifting, man-made environment by searching for utilitarian, adaptable solutions. They value tech performance while making smart use of  available and renewable resources. Functionality is prioritised, while looking cool and working well remains key. Interior/sportswear hybrid textiles show smooth surfaces and a fun mash-up of graphic textures. The palette shows uniform blue, asphalt grey and caterpillar yellow.

HERITAGE LUX

Preservers of historic legacies treasure sensuousness alongside the uncanny, enlightenment together with darkness, for a whole new immersive experience. This new narrative translates to a love for luxury and splendour, decoration and embellishment. Finding beauty in history and nature through ornamental patterning and alluring surface enhancement. Reflecting on ancient history results in a palette featuring enigmatic blood red, sapphire and a lustrous mother-of-pearl.

MULTI-LOCAL

Hyper-locals go global, celebrating inclusivity over appropriation, honouring traditional craftsmanship and adjusting the world’s gaze to embrace exchange, creative integrity and diverse identities. Indigenous style meets global influences. This is a celebration of crafted and decorative pattern, from tribal and folkloric to geometric and abstract. Textile colours become part of a wider cultural narrative, linked to local community, cultural heritage and private identity.

• 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.
