The present invention provides a method for forming a composite part. The method includes providing a forming surface (160), which can be either generally flat or curved depending upon the shape of the composite to be formed. Providing a pre-form part with a part structure adapted to engage the forming surface. The part structure is defined by the arrangement of a plurality of electrically conductive carbon fibers. Placing the pre-form part on the forming surface. Injecting or infusing resin (118), either thermoset or thermoplastic, into the pre-form part via an injection port. Applying an electric current to the carbon fibers to resistively heat the carbon fibers and the pre-form part. As the pre-form part is heated, the resin permeates the part and current is further applied until the part sets. According to another aspect of the invention, the carbon fibers are combined with non-electrically conductive fibers to form either a flat or curved part structure. Additionally, the non-conductive fibers may be thermoplastic fibers that will form the resin matrix of the part and possibly eliminate any further injection of resin. |
