Technical Details & Test Data
- Curing Conditions
- 2 hours at 175°C and 700kN/m2 (7 bar) pressure.
- Heat up rate 2°C to 5°C.
Components up to 30 mm thick can be cured without a dwell in the schedule provided that the heat-up rate is not more than 3°C/minute. There is no deterioration in performance after 3 times the recommended cure schedule (verified by interlaminar shear strength tests).
Storage & Handling
- Shelf Life
- Tack Life @ 23°C 10 days (still processable for up to 21 days).
- Guaranteed Shelf Life @ -18°C 12 months (maximum, from date of manufacture)
- Storage
Storage conditions.
- HexPlyS 6376 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).
