Abstract

A structural component is disclosed which includes first and second extrusions each consisting of a plurality of strengthening fibers. A third extrusion comprises a thermoplastic matrix that encapsulates the first and second extrusions. The three extrusions together define a non-planar cross sectional configuration of substantially transverse dimensions sufficient to provide component strength and stiffness. Also disclosed is an elongated structural component formed by extrusion consisting of a first extruded portion of a plurality of segments of strengthening fibers joined in a thermoplastic matrix and a second extruded portion comprising a thermoplastic matrix compatible with the first extruded portion. The first and second extruded portions together define a predetermined non-planar cross sectional configuration of substantially transverse dimensions sufficient to provide component strength and stiffness.
