Technical Details & Test Data
- Curing Conditions
HexPly® M95 is specially designed for press cure with hot in/hot out extremely fast cure. Typical press cure cycles are given below.
Press Typical Cure Cycle
- Heat the press and mold to 140°C
- Insert the preform, close the press and apply about 10 bars pressure
- Hold 20 min at 140°C
- Open the press and demold the part
Storage & Handling
- Storage
HexPly® M95 prepregs should be stored as received in a cool dry place or in a refrigerator. Following removal from refrigerated storage, allow the prepreg to reach room temperature before opening the polyethylene bag to avoid moisture condensation. (A full reel in its packaging can take up to 48 hours)
- 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® M95 prepreg, upon receipt by the customer, 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.
