Abstract
A structural tie (10) is made from at least one layer of composite material (20). The composite material has a polymer matrix filled with at least one reinforcing material. In one embodiment, the matrix is a thermoplastic and the reinforcing material is fibers encapsulated by the thermoplastic. A structural tie (10) may be selectively formable, in situ, by applying heat to cause the matrix material to soften. Once softened, the structural tie can be conformed to an adjacent surface. The structural tie may include layers (20, 22) of composite material bonded to one another. Optionally, the structural tie is a hybrid of a composite material and a metallic material bonded together. A structural tie may be heat-bondable to a structural member (24).
