A preformed component or "preform" for a structural member has a planar base with two longitudinal legs extending in parallel from the base. A channel is defined between the legs for insertion of a flat plate that forms the first member of the structural member. The base of the preform is bonded to a composite panel. The preform is a composite material having continuous filaments of woven or braided fiber. The preform is impregnated with a thermoset resin that bonds the first member to the second member of the structural member. The preform may have filaments in the legs having a coefficient of expansion to match the plate, and filaments in the base having a coefficient of expansion to match the panel.
