From the Sector

At home, at work, on the street, in the sky, on the water, even in space, technical textiles and nonwovens are swinging towards ever higher performances in amazing applications. Versatile and light, but sometimes stronger than metal, these materials of the future gain their superpowers from the interaction of precisely coordinated textile systems. At Techtextil in Frankfurt am Main from May 14 to 17, 2019 in Hall 3, B06, Oerlikon will be showing chemical fiber applications made of polyester, polypropylene and Co. and what they can do in these fields. However, these exhibits are only a communicative means to an end, as Oerlikon is primarily interested in placing the associated machinery and plant solutions at the centre of discussions with trade fair visitors.

More than two thirds of all technical innovations are directly or indirectly based on new materials, says the German Research Ministry. One could add: The key to a more advanced world, for technological products with amazing functions, breathtaking performance and greater environmental benefits, is also to improve the properties and processing of materials. This applies first and foremost to textiles. Probably no other fabric is so strong as a "team player" who draws its strength from its cohesion. A single polyester thread, for example, looks inconspicuous. Processed into a thigh-thick special weave, however, high-strength High Modulus/High Tenacity fibers anchor floating oil platforms in the deepest waters. These kilometer-long "Mooring Ropes" withstand a breaking load of well over 1,000 tons and perform their task better than steel. For decades, Oerlikon Barmag has been offering special solutions for the production of so-called industrial yarns (IDY) that are tailored to customers worldwide. "We will once again be presenting numerous innovations at this trade fair to inspire our customers," explains Dr.-Ing. Dipl.-Chem. Roy Dolmans, Technology Manager IDY and R&D Filament Processing.

• essenscia Innovation Award is Belgium’s most prestigious prize for industrial innovation
• UltraBond is a cost-effective solution for fully recyclable, latex-free, sustainable carpets
• Significant reductions in ecological footprint and cost for carpet manufacturers

Beaulieu Fibres International, Europe’s largest producer of polyolefin fibres, was nominated for the 2019 essenscia Innovation Award for its recently introduced UltraBond fibre.

The biannual award is the most prestigious prize for industrial innovation in Belgium. Created by essenscia, the Belgian Federation for Chemistry and Life Sciences industries, it aims to promote innovations in the Belgian industry and encourages companies to invest even more in innovative and sustainable products and applications. During the evaluation of the nominated innovation projects, the jury assesses their link with chemistry, life sciences and materials, their contribution to sustainable development, their intellectual property management strategy as well as their added value for the economy.

Formally introduced in early 2019, UltraBond is a patented polyolefin bonding staple fibre that eliminates the need for latex or other chemical binders to bond nonwovens. It enables carpet manufacturers to create 100% PP needlepunch carpets that meet the same performance requirements as traditional constructions, while also reducing end-of-life environmental impact.

UltraBond helps manufacturers make a significant contribution to the circular economy through the production of 100% recyclable carpets. In addition to making recycled PP available for the plastics production chain and reduced waste generation, their total lack of water use and reduced energy use result in significant environmental advantages and financial savings. There is also a reduction in the VOC level of the carpet. This all leads to a significant reduction in a needlepunch carpet’s ecological footprint to the tune of a 35% reduction in CO2 emissions during the full production process.

It is denim season again and we all eagerly anticipate what’s next; what will follow on from trends in eco-responsible production, gender adaptability in styling and innovations to deliver true consumer personalisation? What will be the big new denim story? Is the skinny jean dead yet?

Whether it’s the re-invented five pocket jean with wide or tapered leg shaping or a chino style sitting high at the waist, one thing remains constant- jeans must fit perfectly! Consumers face this problem every season, as brands adopt new design trends. As an industry how can we best deliver fashion, newness and also democratise fit?

• 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.

At the joint stand of the Aachen Centre for Integrative Lightweight Construction (AZL) in Hall 5A, booth D17, the Institut für Textiltechnik of RWTH Aachen University (ITA) will demonstrate its expertise in the field of glass fibres, preforms and textile concrete 12-14 March 2019 in Paris.
The exhibits come from various fields of application and address the automotive, aerospace and mechanical engineering sectors.

1. Innovative glass fibre research at ITA
   The newly constructed induction heated glass fibre production line enables increased flexibility in research. For the first time, glass fibres will be produced live at the ITA booth at JEC World. One of the innovations of the system is the inductively heated bushing. It features a flexible design and consists of a platinum/rhodium alloy (Pt/Rh20) for use in high-temperature glasses.
   The glass fibre production line was designed in such a way that new concepts and ideas can be tested quickly. The modular design allows a high flexibility, the induction system a significantly faster operability.
   Research and development projects can therefore be carried out faster and more cost-effectively.
    
2. DrapeCube - Forming of textile semi-finished products
   The DrapeCube offers a cost-effective design for the production of fibre preforms from textile semi-finished products. It is used in the production of preforms for prototypes and in small series and is suit-able for companies active in the production of fibre-reinforced plas-tics (FRP).
   In the production of FRP components, the preforming process de-fines a large part of the subsequent component costs. In small- and medium-sized enterprises, this process step is often still carried out manually. This results in high quality fluctuations and component prices. Especially in the case of highly stressed structural components, the fluctuation in quality leads to oversizing of the components.
   Thus, the lightweight construction potential of fiber-reinforced plastics is underused. One solution is offered by the stamp forming process adapted from the sheet metal forming industry for shaping rein-forcing textiles. The textile is inserted between two mould halves (male and female) and automatically formed. Due to high plant and tooling costs, this process is used almost exclusively in large-scale production.
   The ITA has developed the DrapeCube forming station which offers a cost-effective alternative and is able to completely reproduce the current state of the art for forming textile half branches. The process steps will be demonstrated in a video at the booth.
    
3. Carbon fibre reinforced plastic (CFRP) preform
   The CFRP preform consists of carbon multiaxial fabrics formed by expanded polystyrene (EPS) to optimise draping quality. Preforms of increased quality can be produced by gentle, textile-compatible forming with foam expansion. For the first time, foam expansion was used to form preforms in such a way that the draping quality is improved compared to classic stamp forming.
   The advantages of the CFRP preform lie in the savings in plant costs, as the investment is much lower. In addition, the proportion of waste is reduced because near-net-shape production is possible. In addition, rejects are reduced, as fewer faults occur in the textile.
    
4. Embroidered preform with integrated metal insert
   The 12k carbon fibre rovings are shaped into a preform using Tai-lored Fibre Placement (TFP) which is a technical embroidery pro-cess. For the further layer build-up, a fastener is not only integrated under the roving layers but also fixed by additional loops. The highly integrative preforming approach offers the possibility of reducing weight and process steps as well as increasing mechanical perfor-mance.
   Until now, inserts were glued or holes had to be drilled in the com-ponent. Bonded fasteners are limited by the adhesive surface. The bonding of fasteners into drilled holes results in high drill abrasion and thus high tool wear.
   The advantages of the embroidered preform with integrated metal fasteners are the reduction of scrap due to TFP preforming and the increase in the specific pull-out force. In addition, it is possible to automatize the production of integrative preforms. This makes the preform with integrated metal fasteners interesting for the automotive and aerospace industries.

• Innovative BCF S8 platform technology opens up new carpet yarn industry markets for Oerlikon Neumag customers

World premiere at the DOMOTEX World Trade Fair for Carpets and Floor Coverings in Hanover: between January 11 bis 14, 2019‎, Oerlikon Neumag will be showcasing its innovative new development, the BCF S8, to a wide audience for the very first time in Hall 11, Stand B36. Whether commodities or niche products – the new BCF S8 platform technology offers manufacturers of BCF carpet yarns decisive arguments for responding to constantly rising cost pressures and the trend for greater efficiency and quality in fiercely-competitive markets. World record: the system achieves never-seen-before spinning speeds and is able to simultaneously spin up to 700 filaments and produce fine titers of up to 2.5 dpf. This superlative performance is guaranteed by numerous individual innovations in the new platform and, for the first time, also in a new human-machine interface (HMI)-based control system, which opens the door to the digital age of smart carpet yarn manufacturing wide. At the ITMA ASIA 2018, the Oerlikon Manmade Fibers segment had already announced that it would be presenting revolutionary solutions in 2019 – both in hardware and software. And the DOMOTEX marks only the start.

According to manufacturer information, the new BCF S8 is the most efficient Oerlikon Neumag BCF system of all times. “We have succeeded in achieving a new level of greater productivity and even broader product diversity. These allow our clientèle to better cater to changing market requirements and achieve a competitive edge in tough market conditions”, explains Martin Rademacher, Vice President Sales Oerlikon Neumag. As a pre-taste, the machine specialists from Neumünster are serving up performance figures and results from comprehensive trials conducted at their own BCF technology center as well as from two pilot systems which have been tried and tested within the market for months now.

BCF S8 performance in numbers
With up to 700 potential filaments per yarn end, the BCF S8 is raising the benchmark considerably compared to the Oerlikon Neumag S+ BCF system (400 filaments) that has dominated the global market to date. Oerlikon Neumag guarantees fine titers of up to 2.5 dpf. Furthermore, the process speed is higher than ever before – 3,700 m/min (winder speed). This permits throughputs of up to 15 percent greater compared to predecessor technologies. Overall, system efficiency is 99 percent – almost unbeatable. True to the Oerlikon Segments Manmade Fibers segment e-save philosophy, energy savings of up to 5 percent per kilogram of yarn are achievable.

BCF S8 innovations – from straight yarn paths to large cooling drums

This comprehensive progress has been achieved with numerous smart innovations. To this end, one key element above all has been optimized. The yarn path from the spinning system to the new, large cooling drum has now been almost completely straightened. This yarn path, unique to the BCF market to date, ensures that the individual filaments are subjected to minimum friction, hence once again considerably reducing yarn breaks and optimizing the overall production process. Especially noteworthy here are the, for the first time, straight yarn inlet in the texturing head – guaranteeing superior yarn quality.

And the considerably reduced distance between the heating godet duo and the texturing head also has a positive impact on the texturing process. It ensures a more even twist to the yarn and reduces the compressed air consumption. Furthermore, the texturing chambers can be removed individually, which additionally shortens servicing times. The now closed units also provide the best possible protection for the texturing jets and lamellar chambers.

The 800-mm diameter cooling drum optimally and gently cools the filaments. And this has a positive influence on the yarn quality. The new cooling drum is now equipped with a V groove for all polymers (PET, PA6 and PP) as standard.

The RoTac3 tangling unit, already established within the market, once again reduces the compressed air consumption by around 50%, while the newly-developed Witras III-37 winder achieves production process speeds of 3,700 m/min.

First intuitively-operable human-machine interface (HMI)
The new BCF S8 is the first Oerlikon Manmade Fibers segment system equipped with the innovative human-machine interface (HMI) for intelligent controlling and monitoring. In this case, the interface between man and machine has been oriented on the daily requirements of users in BCF production. With its new ‘look and feel’, it supports intuitive operation and offers direct access to important information as well as actual and target values at each take-up position by means of a touch screen. A completely new ‘alarm philosophy’ also simplifies troubleshooting and malfunction analysis. “This smart HMI system is a logical step in the digitalization of our products”, explains Dr. Friedrich Lennemann, Vice President R&D Oerlikon Neumag.

To receive an award at PERFORMANCE DAYS is the ultimate industry recognition. In selecting the winners of the (ECO) PERFORMANCE AWARDS, the jury handles with total integrity with no outside influence and is absolutely free in making its decisions. This season there are so many outstanding innovations at the exhibition that two awards are announced!

WATER – OUR RESPONSIBILITY, the current FOCUS TOPIC for the next trade fair on November 28-29th, seems to have spurred the PERFORMANCE DAYS exhibitors to peak performances. The trade fair has highlighted innovations every season for the past ten years, but seldom have there been so many outstanding new developments. So many in fact, that two awards are to be presented: the ECO PERFORMANCE AWARD for best sustainable development, and the PERFORMANCE AWARD for a new functional highlight.  

And the winner of the ECO PERFORMANCE AWARD is:
The jury is highly enthusiastic about the nomination of the ECO PERFORMANCE AWARD winner and described the award-winning fabric as the best ecological solution currently available on the market. This extraordinary laminate from Jou Jou Fish combines various sustainable technologies. Article "JYRNP0002 307" consists of 100% recycled nylon and is designed with a micro-porous membrane (functional performance 15K/10K) that is produced without solvents. This saves a lot of water, plus the fabric is made from pre-dyed fibres (solution-dyeing) and the DWR coating is applied using a dry-finish treatment. The only thing that could improve it: as the polyamide is currently produced from postindustrial waste products, it would be nice to have option of using post-consumer polyamides in the future.

And the winner of the PERFORMANCE AWARD is:
The PERFORMANCE AWARD recognizes another pioneering development. Never before has there been such a fine, yet still tear resistant, highly functional fabric. The winner is article "DPQ 1092 DWR" from Green Threads and with only 17g/m² an absolute lightweight. Particularly fine nylon yarns are used (7d and 4d); a 4d yarn has never before been used in functional fabrics. This plus the extremely good tear resistance clinched it for the jury. Another plus for the winner: this lightweight fabric can achieve with just 17 g comparable performance values to a 50g fabric; thereby, not only is the weight significantly reduced, but also the amount of raw materials and energy consumed in production. This is also a factor that protects the environment when the garment is disposed at the end of its useful life.

Twelve companies from eight different countries will receive a JEC Innovation Award at JEC Asia 2018. Asia-Pacific is an innovative region that sets the tone for all other regions of the globe. Once again, the JEC Innovation Awards highlight how composites bring solutions considering the new challenges in terms of efficiency, sustainability and life-cycle analysis.

This year, JEC Group awards innovations in the following categories: aerospace (structural and tooling), automotive, commercial vehicles, e-mobility, marine, railway, sports & leisure, infrastructure & civil engineering, industrial equipment, sustainability and additive manufacturing.

The ceremony will take place on Thursday November 15, 2018 at the COEX Center of Seoul (South Korea). Ida DAUSSY (Seo Hye-na), will host the ceremony in front of officials, manufacturers, scientists and composites professionals.

Category: AEROSPACE – STRUCTURAL
Winner: CSIR National Aerospace Laboratories (India)

Most of the composite structures for aircraft are made of carbon-epoxy composites, which can withstand a maximum service temperature of 130°C. As a consequence, carbon-epoxy materials cannot be used in hot zones like engine vicinity areas. The Aeronautical Development Agency (ADA) and CSIR-NAL took up the challenge of developing high temperature resistant composites for use in hot zones of light combat aircraft, which would result in significant weight and cost savings, as well as a considerable reduction in the meantime between failures (MTBF) due to thermal ageing.

The first task was to choose a material system with a service temperature of about ~ 200°C. During the material selection process, it was found that BMI resins are a relatively young class of thermosetting polymers. Hence, a carbon-BMI prepreg was selected due to a number of unique features including excellent physical property retention at elevated temperatures and in wet environments.

It was realized that weight savings and performance can be maximized using co-curing technology. This results in a large reduction of fabrication cycle times, costs and weight. Co-cured structures have fewer fasteners, which results in shorter assembly cycle times and also reduces sealing issues.

A prototype engine bay door assembly was built and tested at 180°C for flight certification. The engine bay door consists of an inner skin and co-cured outer skin assembly with eight transverse stiffeners. The stiffeners were designed with ‘J’ sections. The door size was 1.5 m length, 1 m width and 0.4 m overall depth. The co-cured door was developed using autoclave moulding. Two doors were installed in prototype aircraft and successfully flown.
