  • Patent number: 5122323
    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.
    Type: Grant

  • Patent number: 5106282
    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.
