Abstract
A method of manufacturing a flexible element configured for pressing against composite material received on a mold surface of a mold during cure, including placing a porous material over the mold surface, forming a sealed enclosure containing the mold surface and the porous material, infusing a curable liquid material such as silicone in liquid form into the enclosure under vacuum and through the porous material, curing the liquid material to form the flexible element, and opening the enclosure and disengaging the flexible element from the mold. In a particular embodiment, the flexible element is a pressure pad.
