ABSTRACT:
An apparatus is disclosed for rapidly laying up and curing thick complex shaped resin matrix composites connected to a rotatable and alterable male mold to wrap a plurality of continuous and intermittent layers of uncured laminate around the male mold when said mold is in a closed position; moving the male mold into a female mold and thereafter severing all layers on the male mold and articulate the male mold to an open position which shapes the upper regions of the composite and thereafter transferring the resin matrix composite to a female mold which shapes the composite in a desired configuration and thereafter heat cures the composite lay-up while being subjected to a vacuum. A second embodiment of the invention uses a non-rotatable male mold.
