From the Sector

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

The acoustic performance of components for the vehicle interior such as inner dashes or carpets depends on the noise-reducing quality as well as the geometrical adaptability and fill power of their material. With Flexi-Loft, Autoneum offers a new felt-based technology that thanks to a unique blend of recycled cotton and functional fibers reduces product weight and allows for accurate adaptation even to complex shapes. The textile material therefore provides a versatile and more sustainable alternative to foam.

In order to achieve high acoustic performance at minimum weight and maximum sustainability, Autoneum is continuously advancing its textile product portfolio. When it comes to components for the vehicle interior, for example, standard thermoplastic felts excel through their acoustic absorption, robustness and environmental friendliness. However, since felt-based materials are generally less voluminous and moldable as foam components, they require more weight to thoroughly fill the areas of varying thickness between the surface of the component and the vehicle’s body-in-white. In contrast, Autoneum’s Flexi-Loft technology is significantly lighter, more flexible and more adaptable than standard felts. In addition, the fiber-based material is versatile and clearly outperforms current foam products in terms of sustainability.

Thanks to its blend of recycled cotton and polyester fibers, Flexi-Loft substantially reduces component weight while improving geometrical adaptability and acoustic performance, especially in areas of low thickness. Thanks to the specific properties of the fibers, Flexi-Loft enables a precise adaptation to a wide variety of vehicle bodies, thereby improving the noise-insulating qualities of the respective product. Even at low weight, Flexi-Loft covers a wide range of material thicknesses, thus proving to be an ideal decoupling material for interior components with complex shapes such as inner dashes and automotive carpets. As a lightweight, flexible and sustainable alternative to both standard felts and foam, Flexi-Loft distinguishes itself by its versatile application in combination with existing Autoneum technologies such as Hybrid-Acoustics and Prime-Light. Moreover, the material helps to reduce odor and dust inside the vehicle.

Flexi-Loft consists of at least 50% recycled cotton fibers, and cut-offs generated during the manufacturing process are reclaimed, processed and then reused in the production of new felt blanks.

Autoneum is already using Flexi-Loft worldwide as an insulator for various carpets, inner dashes and other acoustic components based on its Prime-Light technology. The application of the material as an effective decoupler in inner dashes made of Hybrid-Acoustics will be launched on the European market in 2023.

• COMPOSITES SUSTAINABILITY REPORT 2021  

JEC Group in collaboration with EuCIA has published the first edition of the Composites Sustainability report 2021. This report seeks to give highlights about the part composite materials are playing in creating the sustainable European economy of the future.   

The contents of the book are comprehensive: starting with discussions around the widely recognised Life  Cycle  Assessment  methodology  for  calculating  the  environmental  impact  of  products,  it then 
moves through a series of analyses and case studies presenting the Circular Economy approach and ranging from raw materials (including bio-based) to industrial components.    

The purpose of the work, rather than results, which quickly become obsolete, is to give examples of approaches contributing to and moving towards sustainability. To do so, JEC Group has arbitrarily split
the value chain into five parts:
• Background, LCA, circular economy ;  
• Concept, design, raw materials ;  
• Production, processes, waste ;  
• Recycling, recovery ;
• Applications. 
 
The book “Composites sustainability Report 2021” is for sale online.

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.

• FILO, 29th-30th September 2021, booth C5

Bemberg™ by Asahi Kasei has been invited to showcase at Filo fair, the international exhibition of orthogonal weaving yarns for clothing and furnishings, circular knitwear and technical textiles, in a new special area, a dedicated open space reserved to sustainable fibers that will allow visitors to discover all their production cycle and performances, in full relax and transparency.

Bemberg™, an exceptional fiber made from the smart-tech transformation of cotton linters pre-consumer materials and converted through a traceable and transparent closed loop process, will brings to Filo its history, experience, know-how and market partnerships to prove its versatility and design-driven look and touch Last but not least we are talking about a true circular economy-oriented ingredient, with certified sustainable performance: Bemberg™ is biodegradable and compostable material as verified by the INNOVHUB 3rd party test and it has GRS (Global Reycled Standard) certification from Textile Exchange proving recycling authenticity.

Bemberg™ application history starts with high-quality suit lining, but today we can find it in many other applications such as fashion couture, outerwear, innerwear, bedding, and sportswear where its amazing unique touch and quality is offering a distinctive performance.

And to prove all of this, Bemberg™ will be at Filo showing some selected fabric innovation, and three responsible-driven designers representing different and complementary part of contemporary consumer wardrobe: ZEROBARRACENTO, Maurizio Miri and WAXEWUL - who have all chosen Bemberg™ fiber to create special collections. Three different ways to see and represent how sustainability and style – even if completely different ones – together can be highly successful, performing and interesting to the new consumer.

ZEROBARRACENTO, a gender-neutral emerging outerwear brand focusing on zero-waste product development, selects Bemberg™ for two fundamental reasons: firstly, from a stylistic point of view for its extreme versatility: in the various collections we have adopted it to create Kimonos, padded jackets, wrap dresses as well as for the interiors of our garments, which are intended to be soft embraces for total physical and mental comfort. The second but no less important reason is that this fibre has circular values in line with their zero-waste commitment.

The concept of the brand "Maurizio Miri" has a strong personality and a clear intent: to create a product that stimulates the wearer towards beauty. A garment should not simply be worn, but it has also to create a perfect symbiosis with the person wearing it and generate an exchange of positive energies. The purpose is to make the individual feel in perfect harmony with their own image. With this aim in mind, the designer selects extremely precious Bemberg™ linings for their sophisticated tailor jackets. 

Finally, WAXEWUL, a brand of sartorial clothing and artisan accessories with an urban-afro soul that has environmental and social sustainability as its basic ethics. WAXEWUL will bring to Filo its brand-new product, the J_Hood Bag: a doubleface jacket with a comfortably removable hood that can be transformed into a finely hidden doubleface bag. An exclusive, innovative and sustainable garment with minimal impact on the environment made of BemBAZIN™ - a new generation of bazin created, patented and produced by Brunello which is composed by the high-tech and responsible fibers of Bemberg™ - on one side and of wax on the other, traceable and certified, guaranteeing a reduction in waste (two jackets in one) and a long-life cycle.
