ABSTRACT:
An apparatus and method for molding structural parts from fiber reinforced plastic composite. The apparatus is comprised of a rigid container, one or more pads of silicone rubber housed inside the container to exert pressure on the part, and one or more expandable diaphragms housed inside the container to control the pressure exerted on the part by the pads. The method used to mold a complex-shaped part from fiber reinforced plastic composite material is to lay up the part on the pads and place the pads, together with the part, between the diaphragms which are housed in the container. The container is then closed and placed in a temperature control chamber and the diaphragms connected to an external pressure control system, after which the part is cured by increasing the temperature of the chamber to the curing temperature of the part, while at the same time controlling the pressure exerted on the part by controlling the pressure in the diaphragms.
