Abstract:
Composite laminate parts are made using a gradient cured subset of fiber reinforced thermoset resin plies. A portion of the subset is cured to rigidity to thereby maintain the shape of a part layup, while other plies in the subset are actively cooled to prevent them from curing. Additional plies are laid up on the uncured plies of the subset to complete the layup. The completed layup is then fully cured.
