An apparatus and method for producing composite structural members on a continuous and automatic basis. In one form, a metal, such as aluminum, is continuously extruded, die rolled or die driven to shape or by a combination of such operations and a high strength plastic polymer, co-polymer or the like is either extruded and laminated to one or more surfaces of the extruded metal structural shape downstream of the die forming same. In another form, two or more metal extrusions are driven parallel to each other while a plastic resin is extruded between same and passed between rolling dies or pulled through a stationary die to form a continuous laminate which is automatically cut to length. In another form, reinforcing fibers are added to the resin. In yet another form, filaments of high strength plastic, glass or carbon are continuously woven into high strength cloth which is fed between continuously fed sheets or structural members of metal and laminated therewith.
