Developed for the high-rate production of structural composite parts, HexPly® M51 prepreg is designed for rapid hot-in/hot-out press curing. It has a 40-minute cure cycle at 180˚C, reducing production times and costs versus standard autoclave-cured prepregs. Using HexPly M51 also reduces the need for multiple sets of tooling and labor compared with conventional prepreg systems. The prepreg is fully compatible with automated tape laying (ATL), automated fiber placement (AFP) and pick-and-place processes. It also is REACH-compliant, demonstrating a mechanical performance equivalent to other state-of-the-art 180°C cure prepregs.
