Technical Details & Test Data
- Curing Conditions
60 mins at 125°C and 700kN/m2 (7 bar) pressure. Heat up rate 2°C to 8°C.
Alternative cure cycles:Temperature °C Time (Min) 140 40 150 20 160 10
Components up to 3 mm thick can be cured without a dwell in the schedule provided that the heat-up rate is not more than 5°C/minute. A dwell period is necessary in the heat-up to avoid the occurrence of a resin exotherm (usually 80 - 100°) but the dwell period will depend on the mass and type of tool.
Storage & Handling
- Storage Life
- Tack Life @ 23°C 30 days
- Guaranteed Shelf Life @ -18°C 12 months (maximum from date of manufacture)
Storage conditions.
HexPly® 913 prepregs should be stored as received in a cool dry place or in a refrigerator. After removal from refrigerator storage, prepreg should be allowed to reach room temperature before opening the polythene bag, thus preventing condensation. (A full reel in its packaging can take up to 48 hours).
