Hexcel launches novel RTM resin, rapid-cure prepreg for aerospace
HexPly M51 prepreg and HiFlow HF610F-2 resin add to Hexcel’s delivery of faster cure cycles and thus higher production build rates.

In response to OEM requirements to increase production efficiency, Hexcel (Stamford, Conn., U.S.) has launched two new aerospace material products that each deliver faster cure cycles, enabling higher production build rates.
HexPly M51 is a rapid-curing prepreg designed for hot-in/hot-out press curing. Fully compatible with automated tape laying (ATL), automated fiber placement (AFP) and pick-and-place processes, HexPly M51 is REACH-compliant and has a 40-minute cure cycle at 180˚C. The prepreg was used to manufacture a rib component in partnership with GKN Aerospace (Redditch, U.K.) as part of the ASCEND project.
Hexcel HiFlow HF610F-2 resin is a new resin transfer molding (RTM) resin suitable for high-rate manufacturing of small- to medium-sized parts enabling robust, high-rate injection processes. A part developed by Airbus Stade (Germany) for the Wing of Tomorrow (WOT) project uses HiMax noncrimp fabrics and HiTape unidirectional reinforcements in combination with the new liquid resin to deliver a total molding time of just 30 minutes.
Other examples in which these technologies were incorporated include a shark fin panel, also manufactured for WOT by Airbus UK (Bristol) with HiMax and HexFlow materials, and a carbon fiber-reinforced polymer (CFRP) passenger door beam made by Airbus with HiFlow and HexForce materials.
