    • 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.
    • 本发明提供一种形成复合部件的方法。 该方法包括提供成形表面(160),其可以根据要形成的复合材料的形状大致平坦或弯曲。 提供具有适于接合成形表面的部件结构的预成形部分。 部件结构由多根导电碳纤维的排列限定。 将预成型件放置在成型表面上。 将树脂(118)(热固性材料或热塑性材料)注入或注入预成型零件中,通过注射口。 向碳纤维施加电流以对碳纤维和预成型部分进行电阻加热。 当预成型部件被加热时,树脂渗透部件,并进一步施加电流,直到部件组装。 根据本发明的另一方面,碳纤维与非导电纤维组合以形成平坦或弯曲部分结构。 此外,非导电纤维可以是将形成该部件的树脂基质的热塑性纤维,并可能消除任何进一步的树脂注射。
