ABSTRACT:
An apparatus and method are described for the formation of a three dimensional composite article by use of a flexible male mold placeable within a cavity formed within a rigid female mold. Fibers are initially bound to the surface of the flexible male mold and the mold is thereafter placed inside the female mold cavity. The surface of the flexible male mold is thereafter displaced away from the female mold by the injection of hardenable resin between the molds. The flexible surface is thereafter returned to near its original position adjacent the female mold. The flexible mold includes a chamber defined therein capable of pressurization and depressurization during the fabrication process of the composite article.
