Hexcel and NaCa Systems develop hybrid carbon and wood fiber composite car seat back

Hexcel Corporation (NYSE: HXL). Hexcel is collaborating with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior parts, on the development of a lightweight carbon fiber prepreg and wood fiber composite sportscar seat back using a rapid press molding process. This innovation validates a short cycle time production process for CFRP and wood fiber composite parts and offers a host of benefits to automotive manufacturers.

Hexcel supplies NaCa Systems with an optimized version of its HexPly® M77CS epoxy prepreg material. HexPly® M77CS is a fast curing hotmelt, thermosetting epoxy matrix, specifically designed for prepreg applications for which short cure cycles and clear surfaces with perfect aesthetics are required.

Hexcel’s newly developed version of the M77CS prepreg has an increased resin content to optimize the CFRP to wood fiber composite bond strength despite the slightly higher resin uptake seen with the natural material component. The carbon fiber prepreg is cured at around 145?C for four to five minutes and can be fully integrated into NaCa Systems existing production lines and metallic tooling.

The lightweight seat back demonstrates a 40% weight saving compared to a typical injection molded plastic component whilst also featuring a significantly improved CO2 footprint vs a full carbon part.

Unlike plastic molded parts, the prepreg and wood fiber structure doesn’t produce sharp edged pieces when damaged, significantly increasing passenger safety in a crash scenario. In addition, wood fiber composites also increase sound absorption, contributing to improved NVH damping within the vehicle interior.

“Hexcel has been a fantastic technology partner for our latest natural fiber and carbon composite hybrid parts. For us it is important to work with a prepreg supplier who can tailor the materials to work with our processes and that can deliver consistent quality as we grow rapidly in response to OEM’s continued drive for more sustainable composite solutions”, commented Aleš Kopal - CEO, NaCa Systems.

The NaCa Systems seat back will be on display on the Hexcel stand at JEC World 2020.

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.

JEC Forum Southeast Asia 2026 highlights Taiwan as a strategic hub for the global composites industry

The third edition of JEC Forum organized in Southeast Asia brought together 350+ participants from 22 countries for three active days of high-level Business Meetings, conferences, and networking, emphasizing Southeast Asia’s growing role in the global composites market. Held for the first time in Taipei from 23 to 24 June 2026, following the successful first editions in Bangkok, JEC Forum Southeast Asia 2026 confirmed its position as the region’s leading business platform dedicated to the composites industry.

Rieter sees Barmag integration on track as orders and sales rise

The first half of 2026 was shaped by the successful completion of the largest acquisition in Rieter’s history. The Man-Made Fiber Division enables entry into the growth segment of man-made fibers and sustainably strengthens Rieter’s market position in the Asia region. The expanded Group is now the world’s leading system supplier for the processing of natural and man-made fibers. In the first half of the year, initial cost savings in material costs and operating expenses have already been realized. The targeted synergies are expected to amount to at least CHF 20 million by the end of the 2028 financial year. Due to the completion of the acquisition on February 2, 2026, the first half of the year for the Man-Made Fiber Division only amounts to five months.
