• 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.

As the tradition goes, twice a year the functional fabric fair Performance Days selects the most innovative fabrics, accessories and finishes for their Performance Forum. This year, two functional finishes from textile innovator Devan Chemicals (Moov&Cool® & R-Vital™) were chosen. R-Vital™ was awarded with the ‘100% Jury Like’ stamp, meaning all the members of the Jury selected the sample, a recognition only granted to a handful of the 1400 applications.

R-Vital™ – ‘100% Jury Like’
R-Vital™ is a range of microencapsulated active ingredients that boost textiles with anti-oxidative effects. The microcapsules, attached to the fibre, deliver antioxidants to the body upon friction. The ‘100% Jury Like’ sample is treated with a well-chosen blend of Ubiquinol (Q10), Sea kelp and Thyme oil, which enhances recovery after sports performances. As R-Vital™ is also suitable for other market segments, such as bedding textiles, Devan enables its customers to compose their own blend, allowing them to create truly unique products and hence properties.
Marleen Van der Auwera, BU Manager Health & Wellness is happy to see that R-Vital™ is getting some more attention. “When the technology was first launched about a year ago, we noticed people had some difficulties understanding the concept because it was so revolutionary to them”, she says. “But this recognition really indicates more and more people are seeing its potential.”

Moov&Cool®
Moov&Cool® is a patented polymer technology, providing a cool comfort feel through a combination of durable heat absorption capacity and a unique, balanced moisture transfer system. By lowering the body core temperature, the finishing treatment helps professional athletes to take their performance to the next level. Furthermore, the technology is also designed to enhance comfort during physical activities of recreational athletes.
Moov&Cool® was first launched at Performance Days in April and will be presented in full detail at the upcoming edition, which will take place on November 28^th & 29^th in Munich, Germany.

• Unique, patented 3D printing process enables production of large-scale components
• First direct investment by BASF Venture Capital in a company in China

BASF Venture Capital GmbH is investing in Prismlab, a leading provider of 3D printing processes and 3D printers, headquartered in Shanghai, China. Prismlab has developed a patented printing process that is characterized by a very high printing speed, high level of precision and lower printing costs. BASF’s venture investment will enable Prismlab to further accelerate its product development and innovation while strengthening its market reach to the global market.

“This is our first direct investment in a Chinese company,” said Markus Solibieda, Managing Director of BASF Venture Capital GmbH. “The trailblazing technology from Prismlab allows large and stable components, such as medical braces and anatomical models, to be 3D printed for the first time. This investment supports BASF’s strategy of actively advancing our technologies and expanding our product offering in the 3D printing sector.”

“China is transforming from a manufacturing-driven to an innovation-driven economy. This investment in Prismlab reflects our commitment to further expanding our innovation capabilities in China, and BASF Venture Capital plays an important role in helping us identifying potential partners that lead us to success,” said Dr. Zheng Daqing, BASF’s Senior Vice President, Business and Market Development Greater China.

“The 3D printing technology must continue to evolve before it is set to change the world. At Prismlab, we aim to spearhead and accelerate that change by providing solutions through specialized customization. The investment allows us to stay laser-focused on our R&D capability, a key factor to achieve that goal,” said Mr. Hou Feng, Founder and Chairman of Prismlab.

Prismlab has developed a patented 3D printing process, “Pixel Resolution Enhanced Technology”, based on stereolithography (SLA). SLA allows comparatively large components to be produced using light-curing resins. Prismlab’s technology increases the printing resolution without compromising printing speed. In order to increase the amount of energy brought into a pixel, Prismlab’s technology divides each pixel in the resin into several small sections, which can be cured individually by exposure to LCD light. This makes the energy input into each pixel significantly higher than similar processes that expose each pixel to light once. This allows comparatively large and stable components or numerous parts to be printed in the same production step. With the use of LCD light, it also reduces process costs. This advantage opens opportunities in the footwear and furniture industry.

Along with this patented process, Prismlab also markets 3D printers and other related services. The Prismlab technology can be used in various key customer applications, including invisible braces, and anatomical models for medical, and education and training purposes.

SLA uses a laser for layer-by-layer curing of a photopolymer solution to shape the required workpiece. SLA and LCD based printing processes determinate the size, stability, and usability of the components to be produced as they are limited by the size of the light spot and the intensity of the light.

RONSE, Belgium - Textile finishing expert, Devan Chemicals, launched its brand-new, patent-pending Moov&Cool technology at Performance Days (18-19 April) in Munich. Detailed as a 'cool comfort technology', the innovation has the potential to improve the athletic performances of both amateurs and professionals alike by regulating core body temperature.

Moov&Cool, Devan’s latest textile finish, consists of a multi-functional polymer technology that absorbs heat during performance and improves the moisture management properties of the fabric. Applied by either padding or spray, the treatment targets and regulates core body temperature and simultaneously reacts to sweat build up and heat emission.

Devan’s technology has been brought to life in an effort to boost the performances of athletes. The company collaborated with the University of Leuven (Belgium) and the Bakala Academy to evaluate and prove the finishing technology. According to Devan, the first results look promising as they have seen an effect on heart rate and lactate levels. Furthermore, the first test results also highlighted a decrease in core temperature of around 0.4°C.

Devan will continue testing in order to evaluate the impact of Moov&Cool when applied to different fibre types and fabric structures. The company aims to provide different application levels to optimise the benefits of the technology for individual sporting activities where performance intensity may play a major role in the protection required.

•    New, sustainable, ready-to-use solutions for plastic auto parts to support China’s electric vehicle boom
•    Stronger, softer nylon polyamide fibers plus fast processing for clothes, carpets & industrial applications
•    AddWorks blends lower total cost of ownership & reduce production complexity while enhancing performance

Muttenz, May 3, 2018 – Clariant, a world leader in specialty chemicals, introduced new additive solutions for plastics materials at Chinaplas 2018.

“Our innovations focus on higher performance at better convenience for a sustainable future,” says Stephan Lynen, Head of Clariant BU Additives. “At Chinaplas 2018 we demonstrated our technical and market capabilities around the theme of e-mobility. The immense changes in mobility call for lighter, safer and smarter vehicles. We offer new additive solutions, such as AddWorks, and technical capabilities to respond to this demand. We are accompanying this with a series of investments such as new production facilities in China.”

Clariant’s new AddWorks solutions – AddWorksATR 146, AddWorks LXR 568 and AddWorks TFB 117 – are specifically aimed at improving performance and efficiency of plastics materials for compounders, polymer and fiber producers in China’s major plastics manufacturing segments. All three solutions are part of the globally available portfolio.

The full AddWorks portfolio consists of differentiated market-specific synergistic additive blends that streamline production processes and create value for customers while enhancing performance. Each solution is customized to specific market needs, underlined by broader considerations such as emission reduction, and less energy and resource usage.

Sustainability and performance for the world’s largest auto market
To support the significant investment in electric vehicles in China, Clariant launched two additive innovations that improve the lifetime of lightweight automotive parts and under-the-hood applications and reduce VOC emissions in an easy to use single solution.

AddWorks ATR 146 is a new low dosage, sulfur-free heat and light stabilizer for filled polypropylene (TPO) compounds used in interior applications. Its exceptional heat and light stability and long term color retention offers the automotive industry unmatched performance. It shows no surface cracking after 700 hours at 150°C, which enables dashboards, instrument panels, door panels and pillars to maintain their aesthetics longer than with traditional stabilizers. It also contributes to reducing blooming and VOC emissions, supporting the common effort to make automotive interiors healthier and odorless.

AddWorks LXR 568 is a high performance processing stabilizer that helps to prevent plastic resins, especially polyolefins, from degradation at high processing temperatures. For the automotive industry, this reduces the tendency of injection molded polypropylene interior car parts to turn brittle during heat exposure, enabling them to maintain a defect-free surface. It also has low migration and low fogging that support healthier in-cab environments.

AddWorks LXR 568 combines outstanding color and melt flow protection with good resistance to hydrolysis and high thermal stability. This makes it ideal for interior and under-the-hood powertrains and wider application areas such as packaging films. It is available in free-flowing pills and micro-pills which are easy and convenient to use.

Softer, stronger polyamide fibers for clothes, carpets and industrial applications
Within the next three years, China is expected to account for 40% of the world’s nylon production and more than 30% of the nylon resin consumed globally[1]. The new AddWorks TFB 117 offers a number of benefits to help stabilize and smoothen fiber production processes, protect color, and improve heat stability and mechanical properties of fibers. AddWorks TFB 117 ensures smooth spinnability with less filaments breakage, even at low processing temperatures and at high speed spinning up to 5,500 m/min.

Martin P. J. John, Head of BL Performance Additives at Clariant, comments: “AddWorks solutions are an ideal fit with China’s priority of achieving more sustainable production. They save time and reduce complexity along the production process, with easy to use formats that reduce health risk and chemical waste. Our new state-of-the-art production facility in Zhenjiang, China, which opens later this year, is dedicated to the manufacturing of AddWorks to deliver innovative solutions tailored to the needs of the market. Made for China in China.

In addition to AddWorks, Clariant presented Exolit® OP 1400, a highly stable non-halogenated flame retardant enhancing safety during the charging process. It also provides outstanding thermal stability for under the hood applications. Exolit OP 1400 has been awarded the Clariant EcoTain® label for outstanding sustainability and performance.  

Clariant also introduced two ranges of performance waxes that smoothen the production of automotive plastics for under the hood applications, Licowax® and Licocare® RBW. The recently launched Licocare RBW is a series of multi-purpose additives based on crude rice bran wax. They offer better shaping flexibility, better mechanical properties and enhanced surface finish, which results in a reduced rejection rate and a more effective dosage.

The market for the production of carpet yarn is increasingly evolving towards more demanding processes. However, beyond commodity products, standard plants can no longer fully exploit their advantages. From 20th to 22nd March 2018, Oerlikon Neumag will be presenting an economical alternative in Shanghai in hall W3, booth F03 at the Domotex asia/Chinafloor, the leading floor covering trade fair in the Asia-Pacific region: the BCF plant Sytec One with single-end technology.

If the requirements for the production of BCF yarns increase, for example, from recycled polyester or fine filaments, then this can also lead to higher breakage rates. Highly standardised production plants must then often strike compromises with regard to throughput, quality or cost-efficiency. In such cases, the Sytec One offers a good solution instead of the mostly three-end technology plants for standard processes.

Single-end technology with 98% productivity

This BCF plant works with only one yarn (end) per position, making it ideal for demanding production processes. The reason: when a yarn break occurs only one yarn tears, all other yarns continue to run. This not only simplifies troubleshooting, it also reduces the re-threading time. In addition, less waste is produced. As a result, the productivity of the Sytec One is still over 98% for ten breakages a day, while a plant with three-end technology only reaches around 92%.

Faster processes due to a straight yarn path

In addition, the absolutely straight yarn path of the Sytec One enables significantly higher process speeds of up to 15% in spinning and texturing processes compared to multi-end technologies. Higher total titers of up to 6,000 dtex can also be produced without any problems. The gentle yarn guidance also ensures minimum friction on the individual filaments. This means less yarn breaks and a more stable process.

Optimised key component: spinning pack

Last but not least, the engineers at Oerlikon Neumag have developed a new design for the spinning pack. This central component of every BCF machine significantly influences the yarn quality. The corresponding solution for the Sytec One optimises the polymer flow in the spin pack, thus reducing the polymer dwell time. This leads to shorter product and colour change times and increases the plant efficiency. In addition, the spinning packs were widened so that yarns with up to 500 filaments can now be produced.

The product mix is decisive

In view of these advantages, the single-end Sytec One is recommended for processes with high breakage rates, fine filaments, frequent colour changes or in general when demanding processes take up an increasing share in the business. "The product mix is decisive for the choice of technology," sums up Alfred Czaplinski, Sales Manager BCF at Oerlikon Neumag. "We are happy to advise on the optimal solution and offer both single-end and three-end plant technologies." 

Good business at the Domotex Hanover, Germany

In the run-up to the trade fair, the Domotex Hanover in mid-January was already proving to be a promising harbinger. With four lively trade fair days and contract conclusions in the lower double-digit million euro range, mainly from the European and Asian markets, the order intake for Oerlikon Neumag was very good.
