摘要： Methods for bonding metallic structures to thermoplastic and thermoset composite structures are described. The methods include steps for preparing the metallic structure (14) for bonding by knurling a mating surface of the metallic structure and molding a layer of thermoplastic material (50) over the knurled mating surface to produce a bonding surface. To bond a metallic structure (14) to a thermoplastic composite structures (16), the bonding surface of the metallic fitting is consolidated with the thermoplastic composite structure (50). To bond a metallic structure to a thermoset composite structure, a bonding surface is formed on the thermoset composite structure by partially embedding a layer of dry fibre reinforcement in a thermoplastic material layer, coating the exposed dry fiber reinforcement with thermoset resin, and curing the coating dry fiber reinforcement into the thermoset composite structure. The bonding surfaces of the thermoset composite structure and the metallic structure are then fused together by applying heat sufficient to melt the thermoplastic material layers of the bonding surfaces. A resistance heating element (54) is disposed between the bonding surfaces of the thermoset composite structure (16) and the metallic structure to provide the heat required to melt the thermoplastic material layers of the bonding surfaces.

摘要： A heating element for providing localized heating during the thermoplastic bonding of thermoset composite structures is disclosed. Various construction details are developed which disclose an apparatus and method for uniformly heating a bond line. In one embodiment, a heating element (22) includes a resistance heating material (24) sandwiched between two layers of electrical insulation (25) and encased within a layer of thermoplastic material (26). Low resistance electrical leads (28), which extend across the width of the resistance heating material, and a power supply (30) provide electrical energy to raise the temperature of the resistance heating material.
