Abstract
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 panel that forms the web of the structural member. 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 web to the flange of the structural member. The preform provides excellent structural support even if the web and the flange are formed from dissimilar materials such as metallic and composite. The resin is structurally reinforced with oriented fibers in such a manner as to provide coupling strength between the joined members.
