In certain circumstances, such as the production of thick section laminates rapid heat-up rates or highly insulating masters, Toray E760 can undergo exothermic heating leading to rapid temperature rise and component degradation in extreme cases. Where this is likely, a cure incorporating an intermediate dwell is recommended in order to minimize the risk.
- Post Cure
After the initial cure, a post cure up to 200°C may be required to maximize the end use temperature as follows:; Ramp temperature at 2°C/min (3.6°F/min) to 200°C (302°F); Hold at 200°C (392°F) for 2 hours; Cool oven to 60°C (140°F) at 3°C/min (5.4°F/min)

- Composite Materials
- Processing Method
Following removal from refrigerated storage, allow the prepreg to reach room temperature before opening the polythene bag, to avoid moisture condensation. Typically, the thaw time for a full roll of material will be 4 to 6 hours. Cut patterns to size and lay-up the laminate in line with design instructions taking care not to distort the prepreg. If necessary, the tack of the prepreg may be increased by gentle warming with hot air. The lay-up should be vacuum debulked at regular intervals using a P3 (pin pricked) release film on the prepreg surface; a vacuum of 980 mbar (29 in Hg) is applied for 20 minutes. For autoclave cures, use of a nonperforated release film on the prepreg surface trimmed to within 25–30 mm of the prepreg edge is recommended for the cure cycle and a vacuum bag should be installed using standard technique
