Hexcel Showcases Ramp up Enablement Innovation with HexPly® M51 at Paris Air Show 2025

Hexcel, a global leader in advanced composites technologies, is showcasing its next-generation HexPly® M51 prepreg technology at the 2025 Paris Air Show. HexPly®M51 is designed for automated and fast processing to meet future high-rate parts production.

Hexcel will showcase at Paris Air Show innovative structural components with complex shapes that demonstrate the performance, automation compatibility, and production efficiencies made possible by the new rapid curing HexPly® M51 system.  These components include a press moulded Wingbox Rib developed with GKN Aerospace and a high-rate fuselage frame developed by the Duqueine Group.

“At Hexcel, we are committed to supporting the aerospace industry’s transition toward faster and automated manufacturing processes,” said Thierry Merlot, Hexcel President Aerospace Europe, Asia Pacific, Middle East, Africa & Industrial “HexPly® M51 is essential for customers seeking to achieve high production rates, with low energy and flexible process in addition to delivering superior part quality without compromise on mechanical performances.”

HexPly® M51 is a rapid-curing prepreg system designed specifically for hot-in/hot-out press curing of primary structure composite parts. It delivers significantly shorter cure cycles and reduces the need for multiple sets of tooling, ancillary material consumption and manual labor. HexPly®M51 is ideal for aerospace OEMs targeting high-rate production programs with flexible curing possibilities. Fully compatible with automated tape laying (ATL), automated fiber placement (AFP), and pick-and-place technologies, HexPly® M51 supports streamlined manufacturing without compromising material performance.

Two main standout components featuring HexPly M51 will be on display:

• GKN Aerospace Wingbox Rib – Developed as part of the ASCEND project, this thermoset, press-moulded rib exemplifies the scalability of HexPly®M51 for large-volume aerospace components. Its rapid-cure capabilities and automation readiness support GKN Aerospace’s strategy for next-generation aircraft production.
• Duqueine Fuselage Frame – Created within the CORAC program, this fuselage frame has demonstrated processing time reductions of over 50% using HexPly®M51 carbon UD materials. It represents a major step-change in the ability to meet the demands of future high-rate commercial aircraft programs.

By highlighting real-world components and partnerships, Hexcel reaffirms its leadership in advancing material systems that enable faster automated composite manufacturing.
