Abstract
A continuous process method of molding composites. The method includes substantially filling a pressure chamber with a solid flowable polymer. The pressure chamber has a series of subchambers separated by a series of spaced apart baffles, but connected through baffle openings. A tube connects at least two subchambers, a transferring subchamber and a receiving subchamber. The polymer is displaced through the tube producing a polymer flow in the chamber through the baffle openings from the receiving subchamber to the transferring subchamber causing the receiving subchamber to have a higher pressure than the transferring subchamber. A composite precursor is passed through the pressure chamber by entering the precursor through the low pressure transferring subchamber wherein the composite precursor is exposed to pressure caused by the solid flowable polymer in order to cure the composite.
