Hexcel and HP Composites collaborate to develop class a body panels

Hexcel has collaborated with HP Composites S.p.A (HP Composites), a world leader in the production of carbon fiber components for automotive and motorsports, to develop carbon fiber Class A body panels. Hexcel HexPly® XF surfacing technology is being extensively used by the Italian component producer to manufacture external body panels and other components for supercars such as Alfa Romeo’s stunning new supersport sedans, the Giulia GTA, and GTAm.

With five production plants in Italy, HP Composites has built an impressive track record of high-performance composite successes on both road and racetrack. HP has combined this processing expertise with Hexcel HexPly® XF3 surfacing material, HexPly® M47, and HexPly® M49 prepregs, working to the highest standards set by the most prestigious supercar OEMs and leading motorsport teams.

Hexcel’s automotive composites portfolio is the result of decades of industry experience and the creation of strategic partnerships to develop and optimize leading-edge technologies. HexPly XF3 is an epoxy prepreg surface material, developed with processing input from the HP Composites team to address the challenges of producing high-quality Class A automotive body panel surfaces with excellent resistance to aging tests.

Applied as the first ply in the mold and after curing at 120-180?C in an autoclave, HexPly XF3 produces a smooth part surface with no porosity, that requires minimal preparation for painting.

HexPly XF3 is supplied in an easy-to-handle roll format with good tack and drapability. After curing, it can be easily prepared for painting with a rapid sanding process. HP Composites has incorporated automated robotic sanding techniques for this finishing stage with the paint-ready HexPly XF3 surface providing excellent paint adhesion according to EN ISO 2409.

HP Composites typically uses autoclave processing for HexPly XF3 parts, maximizing weight savings and structural performance of the final components. In addition, HP has also developed its own proprietary press and compression molding processes, including Air Press Moulding® technology, compatible with HexPly XF3 and other HexPly prepregs for higher volume production series that require increased production rates.

“Our long-term experience has given us a detailed understanding of the critical features that influence how prepregs and surfacing technologies interact with different production processes,” said Abramo Levato, General Manager, HP Composites S.p.A. “The relationship we have with Hexcel is both highly technical and highly supportive. As a result we have a complete material package for high-quality Class A body panels that are formulated specifically with our requirements in mind.”

“Combining the expertise of HP with a strong technical interaction and collaborative dialogue, Hexcel and HP were together able to develop the optimum HexPly XF surfacing technology,” said Claude Despierres, VP Sales and Marketing, Hexcel. “With HexPly XF3 we satisfy the toughest industry standards.”

Engineering depth and diversity for composites

Airbond is the latest member of the British Textile Machinery Association (BTMA) to receive recognition for contributions to the composites industry. The engineering firm based in Pontypool, South Wales, has just received the Make UK Energy and Sustainability Award for its Lattice 3D Printing project.

Circulose restarts commercial-scale production at Ortviken plant in Sundsvall

Circulose today announced the restart of its commercial-scale production plant at Ortviken in Sundsvall, Sweden, marking a significant step in scaling next-generation materials for the global fashion industry. The company plans to resume production of CIRCULOSE®, a recycled pulp made entirely from discarded cotton textiles, in the fourth quarter of 2026.

VIATT 2026 to debut German Pavilion, strengthening European participation alongside key Asian textile hubs

Vietnam’s textile and garment sector continues to be a major contributor to the country’s economic growth, with export revenues expected to reach USD 46 billion in 2025, a 5.6% increase from 2024 . From 26 – 28 February, the Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) is set to contribute to economic growth opportunities by accelerating digital transformation and green transition across the entire textile value chain. The upcoming edition will respond to the rising demand for advanced technologies and sustainable materials with the introduction of the German Pavilion, alongside strong exhibitor participation from key Asian sectors, as well as several high-profile fringe events.

Sustainable, lightweight, and sound absorbing: Polyester-based front trunk solution for BEVs

As car manufacturers look to further reduce their carbon footprint, Autoneum has developed an innovative front trunk solution for battery electric vehicles (BEVs), made entirely from polyester-based textile. The Ultra-Silent Frunk offers significant weight reduction, improved acoustic and thermal insulation, and uses up to 70 percent recycled material, supporting sustainable and efficient vehicle design. Autoneum, global technology leader in acoustic and thermal management for vehicles, has already received orders for the new frunk from three major OEMs in Asia and Europe to be built in three BEV models. Series production for two BEVs has been underway in China and Germany since last year.
