First thermoplastic composite structure demonstrator

Hexcel and Arkema achieve a groundbreaking milestone in the field of aeronautical structures with the realization of a first thermoplastic composite structure demonstrator at JEC 2024. This achievement stems from the strategic partnership between Hexcel and Arkema.

The high-performance thermoplastic composite structure was designed and manufactured using HexPly® thermoplastic tapes. These aerospace-grade materials are developed from Arkema’s Kepstan® PEKK resin and Hexcel HexTow® AS7 and IM7 carbon fibers.

The demonstrator project was carried out as part of the collaborative project known as HAICoPAS. The primary goal of HAICoPAS is to optimize the design and production process for unidirectional composite tapes made from high-performance thermoplastic resins and continuous carbon fibers. Additionally, the project aims to develop a more efficient tape placement technology and a novel continuous and dynamic in-situ welding (ISW) assembly system with real-time quality control. Ultimately, the objective is to produce composite parts that can replace metallic materials (such as steel, aluminum, and titanium) in aircraft structures, achieving both cost competitiveness and high production rates.

The work of the project partners has successfully overcome the technological barriers identified at the beginning of the project, including:

1. The development, implementation, and characterization of carbon/thermoplastic (C/PEKK) tapes.

2. The creation of an automated deposition process for consolidation outside of autoclaves.

3. The establishment of the ISW welding technology for assembly.

The definition of elementary parts intended to form the assembled components of the HAICoPAS demonstrator was carried out in close collaboration with an industrial advisory committee comprising Airbus, Safran, Daher, Hutchinson, and ATC. The final version of the aeronautical demonstrator, made from composite tapes and assembled using ISW technology, is currently on display at the JEC World Innovation Planets exhibition in the Mobility section.

This innovative demonstrator was successfully developed within the framework of the collaborative project “HAICoPAS” (Highly Automatized Integrated Composites for Performing Adaptable Structures). The HAICoPAS project is a collaborative initiative led by Hexcel and Arkema, along with their industrial partners (Ingecal, Coriolis Composites, Pinette Emidecau Industries (PEI), and Institut de Soudure). Additionally, a consortium of university laboratories, spearheaded by CNRS and comprising the PIMM (CNRS - Arts et Métiers ParisTech - Cnam) and LTEN (CNRS - Université de Nantes), played a crucial role in this endeavor. The Structuring R&D Project for Competitiveness (PSPC) received support from Bpifrance as part of the Investment for the Future Program and was endorsed by the Polymeris competitiveness cluster.

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.

Mayer & Cie. Global gears up tor ITMA Asia 2026

Mayer & Cie. Global will focus on mattress fabric production at ITMA Asia, taking place in Shanghai from 20 to 24 November 2026. The company will showcase one of its flagship models for this application: the OVJA 2.4 EM. Joining the mattress fabric specialist will be an OV 3.2 QCe, presented at ITMA Asia in a configuration for knitting double-face fabrics in E40. This gives the OV 3.2 QCe a combination of capabilities rarely found in the market. The German textile machinery manufacturer will also introduce its new portfolio strategy and share updates from its development team at its Albstadt headquarters.

FET highlights advances in fibre spinning technology at Dornbirn Global Fiber Congress

Fibre Extrusion Technology Limited (FET) presented its latest developments in fibre spinning technology at the Dornbirn Global Fiber Congress in Austria in September 2026. In a presentation entitled “Spinning a good yarn”, Dr Jonny Hunter examined recent technological developments and challenges facing the fibre industry, highlighting the company's expanding range of specialised fibre extrusion and spinning systems.

Vietnam’s market evolution creates new sourcing opportunities at VIATT 2027

As Vietnam’s textile industry continues to upgrade and scale, new opportunities are emerging for suppliers of advanced raw materials, design-led fabrics, production technologies, and sustainability solutions. The Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) will return 24 – 26 February 2027, presenting a cross-sector platform – spanning apparel, home and technical categories – for overseas companies to connect with manufacturers, brands, sourcing offices, retailers, and industry buyers from Vietnam, ASEAN, and beyond.
