Cure Cycle Optimization of Rapidly Cured Out-Of-Autoclave

Mar 13, 2018 · Therefore, various post-cure durations were employed to cure the developed out-of-autoclave prepreg stacks. Stacking sequences of [0] 16 and [0/90] 4S were both selected. Regardless of the post-cure time, all of the laminates were cured at 120 °C for 1 h, followed by a post-cure stage at 180 °C during which the heating rate was 5 °C/min
