Abstract
A method for curing resin in the fabrication of a composite material is described comprising enclosing the composite material within a flexible vacuum enclosure, and substantially simultaneously pressing the material within the enclosure between first and second platens of a press to preselected pressure, evacuating the enclosure, selectively heating one of the platens according to a preselected scheme to preselected cure temperature to cure the resin within the material, and cooling the other platen to maintain a preselected temperature differential between the platens across the thickness of the material, whereby cure of the resin is effected in the material first near the heated platen and progresses through the thickness of the material toward the cooler platen as the material is heated to the cure temperature.
