A method for molding composite prepregs using high temperature substantially cured thermosetting resins that reduces fiber damage. Fiber plies are impregnated with solutions of high temperature substantially cured thermosetting resins and the plies are stacked to form a prepreg. A solid flowable particulate silicone rubber is caused to apply pressure to the prepreg to form a composite.
This invention makes a significant advance in the field of molding high temperature resin composites by providing methods of molding that reduce fiber damage, shorten molding time and result in denser parts.
