Using recovered resin from discarded car bumpers, Autoneum’s sustainable Re-Liner technology transforms a previously unusable waste product into lightweight and durable wheelhouse outer liners. In addition to their high recycled content, the eco-friendly components require significantly less energy to produce than conventional alternatives. The innovation presents another important step towards a more sustainable circular economy and has now been nominated for the 2023 PACE Award.

Autoneum has been selected as one of the finalists for the 2023 Automotive News PACE Awards. Entering its 29th year, this prestigious award honors superior innovation, technological advancement and business performance among automotive suppliers.

Re-Liner is based on a core of polyolefins recovered from post-consumer bumpers and has a textile top layer made of fibers from recycled materials. “Autoneum has recognized the untapped potential of recovered resin from automotive bumper covers as a resource and is giving this former waste product a second life,” explained Dan Moler. “The core resin of Re-Liner is 100% automotive post-consumer recycled material, not just a filler or additive to a virgin material. Lightweight, durable, and sustainable wheelhouse outer liners based on this technology are expected to reduce waste generated by bumper covers by nearly one million kilograms in 2023.”

For more than a quarter century of a century, the PACE Award has honored innovations driven by automotive suppliers. The award is known in the global automotive industry for identifying and recognizing the latest game-changing innovation: from the plant floor to the product to the showroom. In 2000, Autoneum (then Rieter Automotive) already received a PACE Award for its Ultra-Light technology. In addition, two of the Company’s technologies have also been nominated as finalists in the past: Ultra-Silent in 2010 and Theta-Fiber in 2012.

Freudenberg Performance Materials (Freudenberg) is launching its latest innovation Evolon® Ultra Smooth to serve the specific packaging needs of technical industries.

Evolon® Ultra Smooth fabrics are low-linting, strong and hard-wearing. The new materials are designed for industrial parts and components which require low-friction, sliding behavior during the part packing and handling procedures. Furthermore, they are durably hydrophobic and available in different weights. The reusable textile containers made of Evolon® Ultra Smooth can be used in various industries to pack and transport even very heavy and sensitive parts without damage.

The Evolon® Ultra Smooth materials have a point-sealed patterned white surface which is very different from the standard Evolon® packaging textiles and which makes them easily identifiable.  

Evolon® Ultra Smooth materials protect the surfaces of industrial and automotive parts by avoiding micro-scratches or lint contamination. By using Evolon® Ultra Smooth reusable packaging to transport parts with highly-sensitive surfaces, customers reduce the number of damaged parts and the reject rate. The innovation is available worldwide. As Evolon® Ultra Smooth is 100% made in Europe, European customers benefit from even greater flexibility in the supply chain and quick go-to-market.

OETI – a member of the internationally active TESTEX Group – has bought the German company ECS to expand its service portfolio in the field of personal protective equipment (PPE).

OETI has been offering testing services for textile work clothing since 1983 – for about 40 years. Since the introduction of CE labelling for personal protective equipment and the enactment of the PPE Directive by the European Union in 1993, OETI has not only been testing textile personal protective equipment, but now on also certifies it in conformity with EU standards. In 1995, OETI was certified in Brussels as a Notified Body (0534) for type-examinations and quality assurance monitoring of personal protective equipment end products. Testing and certification is carried out in accordance with the current PPE Regulation (EU) 2016/425.

Testing and Certification Body for Eye and Face Protection, based in Aalen, was founded 15 years ago and is a globally active institution for testing and certification of eye and face protection equipment. The company is one of the leading independent testing institutions for personal protection products in laser applications and for welding work.

ECS tests and evaluates occupational health and safety goggles with and without a filter action, passive and active switching protection filters and shields for welders, and laser protection filters, goggles, and shields. The company also tests the optical properties of sunglasses, sports glasses, ski goggles, swimming goggles and motorbike goggles.

With OETI’s takeover, the ECS location in Aalen is retained, and all employees will continue working at ECS. The new Managing Director of ECS GmbH as of 1 July 2023 is Dipl.-Ing. Rolf Diebolder.

‘We are present on the European market, on the American market and, via a representative office, on the Chinese market. With the aid of the new distribution channels through OETI and TESTEX, we want to steadily advance ECS’ expansion and be present on all five continents’, says Managing Director Rolf Diebolder, explaining his strategic plans for ECS. ‘I would like OETI and ECS to develop a joint strategy in order to be able to offer existing and new customers of both companies a complete package which, when combined, will give us a unique selling point in the marketplace’, says Diebolder.

Diebolder also sees further potential in the cooperation with regard to protective laser clothing. According to him, this is where the laser laboratory commissioned by ECS could be used to make textiles laser-safe. In the future, there will be more and more ‘hand-held’ devices, i.e. laser welding devices, for which gloves and protective jackets are needed.

• ITA Master's graduate wins Hanns Voith Foundation Award 2023

In his Master's thesis, Flávio André Marter Diniz, a graduate of the Institut für Textiltechnik of RWTH Aachen University (ITA), developed ultra-thin polyethylene (PE) carbon fibres with a filament diameter 2-3 times smaller than usual. In addition, the use of PE-based precursors will make it possible to reduce the price of carbon fibres by 50 per cent in the future, thus opening up a wide range of other possible applications in key industries such as wind power, aerospace and automotive. For this groundbreaking development, Marter Diniz was awarded the Hanns Voith Prize with the Hanns Voith Foundation Award in the category "New Materials". The prize is endowed with € 5,000 in prize money.

Flávio André Marter Diniz won the prize in the category "New Materials" for his master thesis entitled "Investigation of the stabilisation and carbonisation process for the production of ultra-thin polyethylene-based carbon fibres".

The use of carbon fibres in highly stressed lightweight construction solutions, such as today's growth applications of wind turbines or pressure tanks, has become indispensable due to their excellent mechanical properties and low density. High manufacturing costs of conventional PAN precursor-based carbon fibres make the material very cost-intensive. In addition, it is not sufficiently available. New manufacturing approaches that develop alternative raw materials and manufacturing processes can be a key and growth engine for further industrial composites applications.

The aim of the work was to develop a new and cost-effective manufacturing process for high-quality ultra-thin carbon fibres using a polyethylene precursor. For this purpose, the sulphonisation process, which is time-consuming today, was to be significantly shortened. As a result, Mr. Marter Diniz produced novel ultra-thin polyethylenebased carbon fibres with a filament diameter < 3 μm with an excellent surface quality of the fibres without detectable structural defects. The fibre diameter is 2-3 times smaller than that of conventional PANbased CF. This provides the basis for mechanically high-quality material properties. At the same time, Mr. Marter Diniz was able to reduce the sulphonisation time by 25 percent. The developed material and technology set important milestones on the way to cheaper carbon fibres. With PE-based precursors, the price of CF can be reduced by 50 percent compared to conventional PAN-based CF.  

A total of five other young scientists were awarded in six categories (Drive Technology, Innovation & Technology/Artificial Intelligence, New Materials, Paper, Hydropower and Economic Sciences. This year, for the 10th time, the Hanns Voith Foundation awarded the Hanns Voith Prize to outstanding young scientists.

• Flame Retardancy for Composites Applications in the Transport Sector

On 10-11 May 2023, the AVK - Industrievereinigung Verstärkte Kunststoffe e. V. in cooperation with the FGK - Forschungsgesellschaft Kunststoffe e.V. in Berlin organised for the first time an international, English-language conference on flame retardancy.

In 18 compact lectures, more than 20 experts informed nearly 80 participants about new developments, requirements and innovations regarding specific flame retardant properties of components made of fibre-reinforced plastics/composites for the transport sector.

Among others, there were presentations by industry representatives from Saertex, BÜFA, Clariant, Diehl Aviation and Airbus, but also from institutes such as the Fraunhofer Institutes or the Federal Institute for Materials Research and Testing. Presentations on the topics of standardisation, raw materials, automotive or recycling were on the agenda, but also flame retardants for connectors and battery housings for electric vehicles or fire-retardant systems for rail vehicles or fire-retardant CFRP made from recycled CF nonwoven were presented.

• Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.  

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.

• Award for near-net-shape 3D meshes for use in fibre-reinforced plastics

As part of the JEC FORUM DACH 2022, the AVK Innovation Awards were presented in Augsburg on November 29th. The innovation price in the category "Research/Science" (first place) was awarded to the team of scientists Dipl.-Ing. Dominik Nuss, Dr.-Ing. Cornelia Sennewald and Prof. Dr.-Ing. habil. Chokri Cherif.

With the development of the pull-off-free Jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM of the TU Dresden for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. There-fore, it is now possible to produce completely new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.

Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is a unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is completely new and has never been carried out in this way before. The fabric structures are characterised by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and further more contributes to the development of completely new fields of application. The technology can be implemented on all Jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.

Professor Chokri Cherif, Institute Director of the ITM, and his team are very pleased about these continuous research success in the constantly growing research field of 3D weaving technology, which are achieved at the ITM in close cooperation with industry and users. "This award is a special honour for our institute and confirms that the many years of our excellent research in the field of near-net-shape 3D weaving for the fibre-reinforced plastics sector plays a significant role and that we are making a significant contribution to the sustainable and resource-efficient production of lightweight structures with our development".
