Abstract
A thermoplastic conformal tool/vacuum bag that is structured to substantially conform to a surface or a cavity in a composite structure is placed proximate to a uncured composite member to fabricate a composite structure. External heat and external pressure are applied to cure the member. The conformal thermoplastic tool/vacuum bag is removed from the cured assembly by reheating, if necessary, to facilitate removal of the tool/vacuum bag.
