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.

1. A structural member, comprising:a web formed from one of a metallic material and a composite material, the web having a pair of longitudinal edges extending in an axial direction; a flange formed from the other of the metallic and composite materials; a preform formed from composite materials and having a base with a pair of axially elongated legs extending therefrom to define a channel therebetween, wherein the preform is formed from filaments that extend through the base and legs; and wherein one of the longitudinal edges of the web is bonded in the channel of the preform and the flange is bonded to a surface of the base of the preform.
