Description: HexPly® M91 is a high performance, very tough epoxy matrix for use in aerospace primary structures and engines. HexPly® M91 is a toughened, controlled flow, epoxy resin system supplied with unidirectional fibers. Benefits and Features - Excellent toughness with very high residual compression strength after impact.
- Good translation of HexTow® fiber properties, both for intermediate modulus and high strength carbon fiber.
- Designed for automation and particularly suited for both automated tape laying (ATL) and advanced fiber placement (AFP)
- Good tack life and out-life, providing flexibility on the shop floor.
- Low exotherm behavior allowing simple cures of thick monolithic structures up to 70mm (2.76”)
- Dry Tg (DMA extrapolated onset E’) of 185°C-190°C (365°F-374°F)
- Good hot-wet performance up to 120°C (250°F)
