Hexcel launches new HexPEKK® EM electromagnetic shielding and radar absorptive technology

Hexcel is pleased to announce the launch of its latest HexAM® materials technology, HexPEKK® EM – an electrically conductive, high-performance, PEKK-based thermoplastic carbon fiber composite additive manufacturing material offering industry-leading performance.

HexPEKK® EM integrates advanced electromagnetic (EM) performance within complex 3D-printed components for the Commercial Aerospace, Defense, and Military sectors. HexPEKK® EM composite components are flight-ready after printing.

Formulated specifically to meet the static electricity management, electromagnetic shielding, and radiation absorption requirements of advanced aircraft applications, the new PEKK carbon-fiber-blended material

delivers unique electrical performance that complements Hexcel’s current portfolio of carbon fiber-based and unfilled neat resin HexPEKK® 100 material offerings. Manufactured using the aerospace industry qualified HexAM® process, HexPEKK® EM components exhibit best-in-class environmental, operational temperature, and chemical resistant performance attainable in the aerospace industry.

By integrating this enhanced EM performance into additive manufactured components, HexPEKK® EM parts do not require costly and time-consuming secondary processing steps, such as the application of conductive coating for the management of electromagnetic interference or radiation absorption.

Target applications for HexPEKK® EM cover a broad range of products such as exterior surfaces, leading edges, air inlets, electronic enclosures, and cockpit structures for commercial airplanes, military aircraft, helicopters, and UAV components.

HexPEKK® EM components will be produced at Hexcel’s Hartford (CT) plant, where the company continues to develop the HexAM® additive manufacturing process using powder bed fusion technology to fundamentally improve the way the world’s aircraft components are manufactured.

Lawrence Varholak, Vice President of Additive Manufacturing at Hexcel, said, “The management of static electricity dissipation, electromagnetic interference, and radiation absorption is extremely important in the design of all air vehicles. The introduction of this advanced additive manufacturing material will enable the fabrication of extremely complex aerostructures with unparalleled structural and electrical functionality. It significantly reduces weight and cost while providing unlimited design flexibility.”

Novel flame-retardant and recyclable fiber-reinforced composite

Airplanes and passenger trains must meet strict safety requirements, including fire safety standards. This calls for materials that are flame-retardant, lightweight, robust, and scalable. Empa researchers, in collaboration with their industry partner Elantas, have now succeeded for the first time in making such a material – a composite – fully recyclable.

WHILL selects Teijin’s tough, lightweight Carbon Fiber Composite for new last-mile mobility

Teijin Limited announced today that WHILL Inc., a global leader in inclusive mobility technology, has selected Sereebo® P CFP series, a carbon fiber-reinforced thermoplastic (CFRTP) material, for key structural components of the upcoming WHILL Model C Lite. Sereebo® P CFP series provides high strength, light weight, design flexibility and system cost advantages to the Model C Lite, which is a battery powered, single-seat, last-mile device. This new model combines maneuverability with light weight and one-handed folding to ensure ease of handling and operation.

Fewer pores, greater impact tolerance: Peter Dornier Foundation Prize 2026 honours material research on fibre-reinforced composite components for aerospace industry

Microscopically small pores that form during manufacture, or barely visible impact damage, can severely impair the load-bearing capacity and service life of fibre-reinforced composite components. Two young researchers have presented groundbreaking work in this field and will both be awarded the 2026 Peter Dornier Foundation Prize: Dr.-Ing. Benedikt Neitzel from the Technical University of Ilmenau for his doctoral thesis on pore minimisation in the RTM process, and Johanna Buschmann, M.Sc., for her master’s thesis, completed at the German Aerospace Centre, on the improved impact tolerance of 3D fabrics compared to 2D laminates.

HeiQ & Archroma and Lenzing & Armedangels win ITMF International Collaboration Awards 2026

The International Textile Manufacturers Federation (ITMF) has named two industry partnerships as winners of the ITMF International Collaboration Awards 2026. The awards go to collaborations between HeiQ and Archroma as well as Lenzing and Armedangels, highlighting joint approaches to innovation and sustainability across different parts of the textile value chain.

180 years of TESTEX: From Zurich silk testing to global certification

For 180 years, TESTEX has developed alongside the textile industry while maintaining the same underlying purpose: creating trust through independent and reliable measurement. Founded in Zurich in 1846 as the Zurich Silk Conditioning Institute, TESTEX has grown from a local institution serving the silk trade into an international Swiss testing and certification institute for textiles and leather.

Moving Advanced Recycling from Innovation to Implementation

The Advanced Recycling Conference 2026 explores technologies, markets, financing and scale-up of innovative recycling solutions for waste streams including mixed plastic waste, textiles and PVC. Europe’s chemical and materials sector faces growing pressure to close carbon loops, strengthen raw-material safety and resilience and meet increasingly ambitious EU recycling targets. Against this backdrop, the Advanced Recycling Conference (ARC) will bring together industry leaders, technology providers, researchers, innovators and policy-makers on 17–18 November 2026 in Cologne, Germany.

German textile industry and retailers form alliance to shape textile EPR system

Germany’s textile and fashion industry and retail sector have joined forces to establish the “Alliance for Textile Circularity” (Allianz für textile Kreisläufe). Initiated by the German Textile and Fashion Industry Association (Gesamtverband textil+mode) and the German Retail Federation (HDE), the alliance aims to contribute industry expertise to the development of Germany’s future Extended Producer Responsibility (EPR) system for textiles and footwear.
