ABSTRACT:
A method to bond metallic structures to thermoset composite structures is described. Various construction details have been developed which provide a method for producing a bond of sufficient strength to transmit torsional and axial loads between the metallic and thermoset composite structures. In one embodiment, the method includes steps to form a bonding surface on a metallic structure by knurling a mating surface of the metallic structure and molding a thermoplastic material over the knurled surface. Further, the method includes steps to form a bonding surface on a thermoset composite structure by partially embedding a layer of dry fiber into a thermoplastic cone, coating the exposed dry fiber with thermoset resin, and curing the coated dry fibers into the thermoset composite structure. The final step is to fuse the two bonding surfaces by applying heat sufficient to melt the thermoplastic material.
