ABSTRACT:
A method for rapidly forming composites by rotating an alterable male mold to wrap a plurality of continuous and intermittent layers of uncured laminate around the male mold when in a closed position and allowing the male mold to be moved into a female mold and to thereafter sever all layers on the male mold into an open position which thereafter transfers the resin matrix composite to a female mold which shapes the composite in a desired configuration and thereafter heat cures the composite lay-up material while being subjected to a vacuum. A second embodiment of the invention uses a non-rotatable male mold.
