Impact resistance meets thermal insulation lightweight composite impact protection plate for electric vehicle batteries

Lightweight composite impact protection plate for electric vehicle batteries - Autoneum’s new impact protection plate, made from thermoplastic composite material, shields the battery of electric vehicles from impact, fire and corrosion.

The lightweight component not only meets the highest requirements in terms of shock resistance and durability but also contributes to improved energy management and thus to a longer range thanks to its thermal insulation properties.

The ongoing transformation of the automotive industry towards an increasingly electrified mobility requires new shielding technologies to protect the battery system in electric vehicles. In this regard, Autoneum’s new impact protection plate offers a high-performance, safe and cost-effective option thanks to its mechanical and thermal insulation properties, low weight and ability to withstand extreme temperatures.

Autoneum’s composite impact protection plate shields the vehicle battery from damage caused by impact, fire and corrosion. It is significantly lighter than metal alternatives and at the same time thermally insulating, which contributes to a longer driving range. In addition, the part meets the highest requirements for impact resistance and springs back into shape without structural loss or deforma-tion even after repeated exposure to stones and road debris. The new impact protection plate is based on long-fiber thermoplastic (LFT) technology, which allows the greatest possible freedom in terms of design and construction as well as waste-free production. Moreover, the additional reinforcement of the basic structure ensures maximum rigidity and impact protection at minimal weight.

The impact protection plate reflects Autoneum’s technological expertise in underbody shields, thermal management and the application of the LFT process, adapted specifically for battery electric vehicles. The technology for the composite impact protection plate has been validated by simulations and vehicle testing at different European OEMs.

Autoneum reports solid revenue, achieves strong EBIT margin of well above 5 percent in fiscal year 2025

Despite a challenging market environment, Autoneum reached key strategic milestones in fiscal year 2025. With two acquisitions in China, the Group significantly strengthened its position in the strategic growth market of Asia.

Autoneum and Polestar set new benchmarks for passenger experience and sustainability

As the global market leader in sustainable acoustic and thermal management, Autoneum is a key supplier of interior and exterior components for the highly anticipated Polestar 5 model. The successful collaboration between Autoneum and Polestar marks a significant milestone in sustainable automotive engineering: the electric grand tourer sports car features several innovations in lightweight, fully recyclable polyester-based components that ensure a superior driving experience. Polestar 5 was revealed at the IAA Mobility 2025 in Munich and is available in 24 markets.

N-Join1: an innovative, adhesive-free carpet that supports the circular economy

Vehicle manufacturers are increasingly looking for recycling solutions for end-of-life vehicles to meet sustainability targets and comply with new regulations that are accelerating the automotive industry’s transition toward a circular economy. In response, Autoneum has developed the N-Join1 carpet. This innovative, monomaterial carpet system, made from recycled materials, eliminates the need for latex and adhesives, thereby offering an eco-friendly solution for vehicle interiors.

MEL Composites delivers advanced hull infusion for Técnico Solar Boat’s hydrogen-powered São Gabriel 01

MEL Composites has reinforced its partnership with Técnico Solar Boat through the successful hull infusion of the São Gabriel 01, an 8m long, 2.4m wide, hydrogen-powered hydrofoiling vessel. Designed to compete at the Monaco Energy Boat Challenge in July 2026, the São Gabriel 01 is the team’s most technically demanding project to date and showcases the future of sustainable marine engineering by combining advanced composite manufacturing with clean energy systems.

Award-winning research for sustainable carbon fibre cycles

Sustainable recycling of carbon fibres is possible through targeted electrochemical surface modification, which makes the sizing of carbon fibres resistant to solvolysis. ITA PhD student Sabina Dann was awarded the MSW Award from RWTH Aachen University for her master's thesis on this development. The award ceremony took place on 12 November 2025 in Aachen.

“Action helps us change what we do!”

DAY 0 takes place deliberately before PERFORMANCE DAYS begins. It is conceived as a space for reflection, dialogue and active engagement — a moment to pause before the fair, rethink established systems and address sustainability not as a trend, but as a fundamental transformation challenge. Under the guiding metaphor “Turn the Tap Off”, DAY 0 focuses on root causes rather than symptoms, systemic change rather than isolated solutions, and collective responsibility rather than individual silos.
