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.”

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.

Cotton Brazil Dialogues 2026 concludes with 50 international participants immersed in Brazilian cotton production

The Cotton Brazil Dialogues concludes its 2026 edition after a series of technical visits to farms, cotton gins and reference centers, as well as workshops focused on Brazilian cotton production. A total of 50 participants from 14 countries took part in the field trips. The initiative is led by the Brazilian Association of Cotton Growers (Abrapa) and the National Association of Cotton Exporters (Anea), with support from the Brazilian Trade and Investment Promotion Agency (ApexBrasil).

ZymoChem secures $4 million in renewed federal funding to advance U.S. biomanufacturing of critical materials and their supply chains

ZymoChem, the specialty chemicals company dedicated to bringing decarbonization, sustainability, and supply chain resiliency to the chemical industry through innovative biological manufacturing, today announced the resumption and expansion of its federal research portfolio. The company has been notified that previously paused work under a $5 million U.S. Department of Energy (DOE) program is officially back on, to be joined by continuing collaborations with three of the nation's premier national laboratories.

RDJ 6/2 in E 32: Finesse in Motion

The appearance of sports and casual shoes is as diverse as their applications, ranging from sporty to stylish and from functional to fashionably practical. In particular, spacer fabrics produced on highly flexible KARL MAYER double needle bar raschel machines with Jacquard technology are in high demand for manufacturing these trendy shoes. These efficient production machines enable attractive designs with integrated multifunctional zones on one or both fabric surfaces, such as breathable mesh structures. Flexible in size and positioning, these features enhance both aesthetics and wearing comfort.
