ABSTRACT:
A method of moulding composite materials in which prepregs of resin impregnated filaments are interposed between a shaped partially contained polytetrafluoroethylene body and a die. The assembly is heated to cause the polytetrafluoroethylene body to thermally expand and compress the prepregs against the die so that the prepregs are moulded to the shape of the die and the resin in the prepregs cures.
