In addition to synthesizing nanotubes, the facility will manufacture nanotube suspensions for lithium-ion battery manufacturers in Europe, the US, and Asia – enough to enhance the performance of more than 1 mln electric cars with an average battery capacity of 75 kWh per car. OCSiAl nanotubes create long and robust electrical networks between active material particles, improving key battery characteristics, including cycle life, lower DCR, C-rate performance, and cohesion between active battery material particles, making the battery electrodes more durable. Graphene nanotubes unlock new battery technologies, including high-silicon content anodes, thick LFP cathodes, fast-charging graphite anodes, and more. They can be applied in both conventional and emerging battery tech, such as a dry battery electrode coating process, and solid-state batteries.
 
As well as synthesizing nanotubes and producing suspensions, OCSiAl project includes manufacturing of nanotube concentrates for high-performance polymers. The project has passed environmental impact assessment and it is 100% powered by green energy. It enjoys support from Serbian municipal and national governments. The plant is planned to be certified in accordance with ISO 9001, ISO 14001, and ISO 45001, and to be compliant with the IATF 16949 automotive industry standard. The project will create more than 200 job opportunities for engineers, scientists, managers, operators, and administrative staff.
 
Currently, OCSiAl has an extensive manufacturing system of nanotube-based products in the regions of highest market demand, such as China, Japan, Sri Lanka, Brazil, Malaysia, and other countries. The Serbia nanotube hub will operate in conjunction with the company’s operational R&D center and planned graphene nanotube synthesis facility in Luxembourg.

Autoneum: Sustainable sound absorption for underbody shields

Silence and resource efficiency are the order of the day in the development and optimization of electric vehicles. On the one hand, ever stricter emissions regulations worldwide are increasing demand for components that reduce noise pollution while helping vehicle manufacturers meet their sustainability targets. On the other hand, the absence of noise from the combustion engine in e-cars amplifies the disruptive effects of other noise sources in the passenger compartment. With Ultra-
Silent Tune, Autoneum now presents a new lightweight and environmentally friendly technology for underbody shields that reduces tire rolling noise both outside and inside the vehicle, thus improving not only acoustic performance but also driver comfort in electric cars.

Silence and resource efficiency are the order of the day in the development and optimization of electric vehicles. On the one hand, ever stricter emissions regulations worldwide are increasing demand for components that reduce noise pollution while helping vehicle manufacturers meet their sustainability targets. On the other hand, the absence of noise from the combustion engine in e-cars amplifies the disruptive effects of other noise sources in the passenger compartment. With Ultra-
Silent Tune, Autoneum now presents a new lightweight and environmentally friendly technology for underbody shields that reduces tire rolling noise both outside and inside the vehicle, thus improving not only acoustic performance but also driver comfort in electric cars.

Autoneum's Ultra-Silent Tune technology owes its sound-absorbing performance to acoustic chambers of different shapes and sizes. The chambers are created by applying an embossed polyester foil to the side of the Ultra-Silent underbody shield facing away from the noise source: they capture the sound waves emitted by the car tires, modulate them according to their respective geometry and reflect them back onto the porous carrier material. Compared to conventional single-layer underbody shields, whose acoustic performance is mainly determined by the noise-reducing properties of the product side facing the tires, Ultra-Silent Tune exploits both sides of the component, which significantly improves its acoustic absorption. Autoneum thus makes innovative use of the proven concept of traditional chamber absorbers, reducing exterior tire rolling noise.

Moreover, Ultra-Silent Tune combines optimized acoustic performance with the sustainability benefits of Autoneum's Pure technology Ultra-Silent. In addition to the high proportion of recycled PET fibers, underbody shields made from Ultra-Silent Tune can be manufactured from 100% polyester and thus be fully recycled at the end of vehicle life. Furthermore, the thickness of the multilayer construction can be flexibly adapted to the packaging spaces of different vehicle models. Underbody shields made from Autoneum's new Ultra-Silent Tune technology are already in pre-development at various vehicle manufacturers in Europe.

Autoneum: Optimized thermal management for electric vehicles thanks to cold chamber

A new cold chamber at its headquarters in Winterthur, Switzerland, enables Autoneum to optimize existing technologies as well as simulation and engineering services in vehicle thermal management and to adapt them to the changing thermal requirements of electric vehicles

The absence of heat from the internal combustion engine in electric vehicles as well as the impact of ambient temperature on the performance and lifetime of lithium-ion batteries are changing the requirements for vehicle thermal management. In addition, the energy from the battery is used not only to power the e-motor but also to thermally manage the battery itself and to warm and cool the car cabin by means of the heating, ventilation and air conditioning system. To increase the thermal comfort of the occupants and at the same time ensure optimum battery performance, save energy and thus increase the car’s range, manufacturers are placing increasing emphasis on efficient overall thermal management of the vehicle.

The chamber enables to test both occupants’ subjective perception of thermal comfort and the performance of components and entire vehicles under controlled temperature conditions of up to minus 20 degrees Celsius. It is thus a valuable addition to the existing testing and bench-marking facilities at the Company’s global research and development centers. The tests conducted in the chamber show how existing insulating components such as under battery shields, carpets and interior trim need to be optimized to further enhance the thermal management of the vehicle battery and cabin. The tests also provide valuable insights regarding the development and optimization of heated surfaces such as floor mats and door trim panels to improve thermal performance and driver comfort of electric vehicles.

Overall prize of the “IQ Innovationspreis Mitteldeutschland“ for FibreCoat GmbH and DBF Deutsche Basalt Faser GmbH

FibreCoat GmbH from Aachen, Germany, together with DBF Deutsche Basalt GmbH, developed a completely new type of fibre material to shield electromagnetic radiation from digital end devices, medical technology or e-car batteries cheaply and effectively. The joint project was awarded the overall prize of the“ IQ Innovationspreises Mitteldeutschland“ on 24 June in an online event broadcast live from Leipzig.

The prize is endowed with €15,000 and was sponsored by the Halle-Dessau, Leipzig and East Thuringia Chambers of Industry and Commerce.

FibreCoat GmbH from Aachen, Germany, together with DBF Deutsche Basalt GmbH, developed a completely new type of fibre material to shield electromagnetic radiation from digital end devices, medical technology or e-car batteries cheaply and effectively. The joint project was awarded the overall prize of the“ IQ Innovationspreises Mitteldeutschland“ on 24 June in an online event broadcast live from Leipzig.

The prize is endowed with €15,000 and was sponsored by the Halle-Dessau, Leipzig and East Thuringia Chambers of Industry and Commerce.

Electromagnetic radiation from smartphones, hospital diagnostics and electric car batteries must be shielded so that they do not inter-fere with each other. To prevent mutual interference, they have so far been covered with metal fibre fabrics, a very time- and energy-consuming and thus expensive procedure. The new material from Basalt Faser GmbH and FibreCoat GmbH prevents this with a fibre core made of melted, thinly drawn basalt, which is coated with aluminium and bundled into the so-called AluCoat yarn. This yarn remains just as conductive and shielding, but is lighter, stronger, cheaper and more sustainable than previous alternatives. In addition, there are further advantages:

  • The number of process steps required is reduced from ten to one.
  • 1,500 metres of yarn are produced per minute instead of the previous five metres.
  • The energy required is only 10 per cent of the previous amount.

The result is a price that is twenty times lower.

The textile made of AluCoat fibres is versatile and flexible: as wallpaper it can shield 5G radiation in offices or medical rooms or encase batteries and thus ensure the smooth functioning of electric cars. AluCoat is already being used in some companies. A European fibre centre in Sangerhausen is being planned for mass production.

The two innovative companies DBF Deutsche Basalt GmbH and FibreCoat GmbH from East and West combine the two materials basalt and aluminium to protect against electromagnetic radiation. In doing so, they coat basalt with aluminium and, through this novel combination, create an inexpensive, sustainable and quickly produced alter-native for a market worth billions.

FibreCoat GmbH from Aachen is a spin-off of the Institut für Textiltechnik (ITA) of RWTH Aachen University; the managing directors Dr Robert Brüll and Alexander Lüking and Richard Haas have completed their doctorates at the ITA or are in the process of preparing their doctorates. Georgi Gogoladze, Managing Director of Deutsche Basaltfaser GmbH, also studied at RWTH Aachen University. The two managing directors Brüll and Gogoladze know each other from their student days.

Chinese Reach Group under the lead of its president Daniel He represented a large portfolio of European companies and their recent developments through their cooperation with Dr. Michael Effing´s AMAC/Germany, among them Airborne (NL), Textechno (D) and Conbility (D).

Daniel He describes the situation: „The Chinese market is picking up again; a price increase of 7% for glass fibers was announced right before the China Composites Show, on August 25th 2020, which was even leading to a temporary material shortage. Today, the most booming industries in China are wind energy, building and infrastructure and innovation for electric cars. Unlike the rest of the world, where the aircraft industry undergoes a deep decline, in China it takes up by 50 %, which is very promising. Furthermore, we expect half a year for a full recovery of the industry, while the China growth of 2020 is still expected to be between 2 and 4 %.“

Michael Effing replied: “Enabling the composites business between China and Europe is the aim of our cooperation with Reach and with our customers, which are active in digital automatization, testing equipment or cost optimization software. We are very happy to have been present in China through our representant Reach and are looking forward to bridge and overcome the Covid-19-crisis with our upcoming event in Germany, the Composites for Europe in Stuttgart in November and hope to be back to full global business speed at the JEC in Paris in 2021.“

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.
