From the Sector

Society and the economy are facing existential challenges. In addition to the consequences of climate change, these include the realisation that energy and many resources are no longer available in the usual quantities, so that their efficiency must be significantly increased in the short term. Lightweight construction, especially with fibre composite materials, can and will make an important contribution here, e.g. in wind power plants or hydrogen storage systems. As an umbrella organisation, Composites Germany represents the capabilities and interests of the German fibre composite industry. With the re-entry of Composites United, Composites Germany will combine the forces of the two leading composites networks in Germany and its position will be significantly strengthened. Changed framework conditions make the re-entry possible and necessary.

VDMA and Leichtbau BW will continue to support the work of Composites Germany as associate members and contribute the know-how of their members. Together, the organisations will promote sustainable lightweight construction as a key technology for Germany, focusing on composites materials, says Prof. Klaus Drechsler of Composites United, one of the two board members of Composites Germany. As a network and mouthpiece of the composites industry, Composites Germany bundles the interests of its members. The aim is to continuously expand activities, promote innovations and technologies, develop new markets and new value chains, and anchor training and further education, adds his board colleague Dr Michael Effing of AVK. The agreement was concluded on 29 November 2022 during the JEC Forum DACH in Augsburg, where both associations were cooperation partners of the event.

The UK’s new Business Secretary, Grant Shapps has visited the Henry Royce Institute’ hub in Manchester to seal the second phase of R&D investment in the institute of £95 million. Fibre Extrusion Technology Limited (FET) of Leeds, England had previously installed its FET-200LAB wet spinning system at the University of Manchester site and this proved to be a focus for the Business Secretary’s interest, as he discussed the project with FET’s Research and Development Manager, Mark Smith.

This wet spinning technology enables fibres to be derived from sustainable wood pulp to produce high quality apparel and trials are now underway to perfect this process. FET is a world leading supplier of laboratory and pilot melt spinning systems, having successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.

During his visit, Shapps spoke of the investment programme as a means of reinforcing the UK’s standing as a leader in advanced materials research, development and innovation.

“R&D investment is a critical way to turbocharge Britain’s growth. Growing an economy fit for the future means harnessing the full potential of advanced materials, making science fiction a reality by supporting projects from regenerative medicine to robots developing new recycling capabilities, right across the country. Today’s £95 million investment will do just that, bringing together the brightest minds across our businesses and institutions to help future-proof sectors from healthcare to nuclear energy.”

The Henry Royce Institute was established in 2015 with an initial £235 million government investment through the Engineering and Physical Sciences Research Council and the latest £95 million sum represents the second phase of the investment.

Opportunities being investigated by Royce include lightweight materials and structures, biomaterials and materials designed for reuse, recycling and remanufacture. Advanced materials are critical to the UK future in various industries, such as health, transport, energy, electronics and utilities.

• Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.

Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.

Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

Inspired by this innate desire to experience nature and a shared vision, adidas TERREX has teamed up with fashion-forward Japanese outdoor label and wander on a collection that will take hikers from city centre to mountain top (and back again) in style.

Since its inception, adidas TERREX has focused on providing people with the clothing and apparel they need to realize their individual goals in the outdoors and enjoy the benefits of nature.

Tokyo designers Keita Ikeuchi and Mihoko Mori, meanwhile, launched their own outdoor label and wander in 2011 to bring more creativity to outdoors wear. By pairing high-fashion design with the practical requirements needed for adventure, theirs is a modern approach to apparel that works both in the wild, and on the streets.  

Together, adidas TERREX and and wander have collaborated on a multi-seasonal collection that ties these philosophies together to help people enjoy more outdoors experiences.

Pincroft, UK’s largest textile dyer, printer and finisher, developed a new camouflage pattern for the Dutch Ministry of Defence as part of their Defensie Materieel Organisatie’s (DMO) ‘STRONG’ programme that aims to supply combat clothing and equipment to all military personnel part of the Royal Netherlands Navy, Army, Air Force and Marechaussee.

The new fabric and camouflage pattern boast the new Netherlands Fractal Pattern and will be used in at least 480,000 sets of uniforms for soldiers worldwide. The camouflage pattern is being manufactured in a green or woodland style for the Army, Air Force, Marechaussee and Marines, while the Navy receives a blue or marine style design. Pincroft followed the guidelines of the new Netherlands Fractal Pattern (NFP) to create an eight-colour camouflage design that provides high levels of disruption to give soldiers better concealment when needed.

The fabric was created by global workwear textile manufacturer, Carrington Textiles, specifically following the Dutch MoD’s requirements on comfort and protection. The result is a lightweight yet durable textile of 210gsm with a composition of 50% cotton, 50% high tenacity nylon and Ripstop for added strength.

The high cotton content of the fabric creates a uniform that’s comfortable to wear due to its softness to the touch, and breathability, as well as providing moisture wicking properties, key elements for the tough conditions soldiers work in. The addition of high tenacity nylon to the fabric, provides added strength and durability, with the Ripstop properties of the fabric offering tear resistance.

Around 480,000 trousers and jackets will be delivered to officers from the Royal Netherlands Navy, Army, Air Force and Marechaussee, during a uniform roll out part of the Dutch MoD’s ‘STRONG’ programme that aims to equip the armed forces in the next 18 months with versatile uniforms and equipment that are adjustable according to the assignment. The pack also includes a raincoat, combat shirt and baseball cap.

• Monomaterial solution contains renewably-sourced polypropylene from the Bornewables™ portfolio of circular polyolefins
• Trexel employs its proprietary MuCell® technology to deliver a range of lightweighting benefits
• EverMinds™ in action: reuse and design for recycling are focus of value chain collaboration

Borealis and Trexel, an expert in foaming injection and blow moulded parts, announce that they have co-developed a new plastic bottle based on a grade from the Bornewables™ portfolio of polyolefins made using renewable feedstocks derived 100% from waste and residue streams. The lightweight bottle – which will be showcased at the Borealis stand at the K 2022 (from 19 to 26 October 2022 in Düsseldorf) – is reusable and fully recyclable. It boasts a significantly lower overall CO₂ footprint because it is composed of renewably-sourced feedstock and produced in the foaming process.

The Bornewables™ portfolio of circular polyolefins helps reduce the carbon footprint while offering material performance equal to virgin polymers. Using Bornewables grades allows for design freedom and colour flexibility, and helps retain a premium look and feel. The grades – which are commercially available in Europe – help conserve natural resources because they are derived solely from waste and residue streams, for example from used cooking oil. Reusing waste already in circulation instead of fossil fuel-based feedstocks enhances the sustainability of applications made using the Bornewables grades.

The reusable new bottle developed by Borealis and Trexel retains its value over many life cycles thanks to the use of Trexel’s proprietary technology in tandem with Bornewables grades; as a material solution, the new bottle minimises the use of valuable raw materials. Moreover, converters consume less energy in the production process when using the MuCell® technology. The bottle thus helps close the loop on plastics circularity by way of design for recycling, the use of renewable feedstocks, and excellent material performance across multiple life cycles.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

Catering to the acoustic requirements of electric vehicles, Autoneum has extended its concepts for noise-reducing engine encapsulations to new applications related to electric drives. Hybrid-Acoustics PET and the foam-based alternatives Hybrid-Acoustics FLEX and Fit FLEX ensure optimum noise protection in e-cars and thus improve driving comfort. All three technologies are characterized by a high acoustic performance tailored to specific customer needs and zero waste production.

Disturbing noises such as the high-frequency sounds of e-motors and other electric devices or the whining noise of the gearbox are posing new acoustic challenges for vehicle manufacturers worldwide. Anticipating the increasing demand for sound-reducing components in both the front and the rear of e-cars early on, Autoneum has expanded its technologies for noise protection in the engine bay to new tailor-made applications for electric vehicles.

With the fibrous technology Hybrid-Acoustics PET and the two foam alternatives Hybrid-Acoustics FLEX and Fit FLEX, the Company offers three standardized technologies that reduce noise directly at the source, thereby improving driver comfort. All three technologies are produced waste-free and their adaptive capacity to different sizes and shapes allows for a broad spectrum of uses in electric vehicles: from e-motor encapsulations to the reduction of noise and vibration of inverters, gearbox, pumps and compressors. By offering both fibrous and foam-based variants, Autoneum is able to flexibly cater to individual customer needs and preferences with regard to material, acoustic concept, sustainability and costs.

In terms of sustainable noise protection in the engine bay, Autoneum’s patented innovation Hybrid-
Acoustics PET sets the tone: it is made of 100 percent PET with up to 50 percent recycled fibers; cut-offs in production are reclaimed, processed and reused and the material can be fully recycled at the end of product life. The unique textile technology, which is part of the Company’s sustainability label Autoneum Pure, is particularly suited to attenuating high-frequency sounds of the electric drive unit and offers the optimum balance of absorption and insulation. Moreover, components made of Hybrid-Acoustics PET are up to 40 percent lighter compared to standard insulators.

To accommodate the differing preferences of vehicle manufacturers, Autoneum has complemented its lightweight textile technology with two foam-based alternatives. Since the foam is injected in both technologies, no waste is generated during production either. Hybrid-Acoustics FLEX is based on the same acoustic concept as Hybrid-Acoustics PET, but the decoupler is made of foam instead of felt. Autoneum’s Fit FLEX, on the other hand, combines the foam decoupler with an injection molded heavy layer. Thanks to the high geometrical adaptability of foam to even complex shapes, both technologies offer outstanding acoustic performance in the insulation of e-motors and other noise sources in electric vehicles. Furthermore, the absorbing or insulating acoustic quality of the foam can be flexibly tuned to specific customer needs.
