- Product Highlights
- 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)

Storage & Handling
- Storage and Handling
- Tack Life: 10 to 15 days at 23°C (73°F) dependent on lay-up process (Hand Lay-Up, ATL, AFP)
- Out Life: 42 days at 23°C (73°F)
- Shelf Life: 12 months at –18°C (0°F) (maximum, from date of manufacture)
Tack Life: The time, at room temperature, during which prepreg retains enough tack for easy component lay-up.
Out Life: The maximum accumulated time allowed at room temperature between removal from the freezer and cure.
Shelf Life: The maximum storage life for HexPly® M91 prepreg, from the date of manufacture, when stored continuously, in a sealed moisture-proof bag, at –18°C (0°F). To accurately establish the exact expiry date, consult the box label.
