Abstract
An out-of-autoclave compression molding system is disclosed herein. The system includes a mold, a vacuum bag, a vacuum valve, a pressure plate, and a pressure valve. The mold includes a concave feature and a flange. The vacuum bag covers at least the concave feature. The pressure plate is positioned outside the vacuum bag clamped to the flange and on the mold to form a pressure cavity between the vacuum bag and the plate. An out-of-autoclave compression molding process is also described. The process includes pressing a composite material and thermoset resin into a mold having a flange; surrounding the mold, composite material, and resin with a vacuum bag; sealing and evacuating the vacuum bag; clamping a pressure plate to the flange; and pressurizing the cavity.
