ABSTRACT:
The present invention relates to a unique fiber-reinforced metallic tubular element, along with a unique method for producing such tubular elements on a production basis. The tubular element includes a cylindrical aluminum tube surrounded by a fiber composite sleeve which includes a plurality of individual reinforcing graphite fibers oriented parallel to the longitudinal axis of the tube and uniformly positioned about the circumference of the tube. In the preferred embodiment of the invention, an isolation layer is positioned between the graphite reinforcing layer and the outer surface of the aluminum tube, and a protective covering layer of fiber material surrounds the tube and is adhered to the outer surface of the graphite reinforcing layer. In the preferred method of the present invention, a plurality of cylindrical metal tubes are coupled to one another in an end-to-end relationship by a plurality of joining plug members to form a longitudinally extending series of metal tubes. The series of metal tubes are fed along a longitudinal axis to an apparatus for applying the individual layers of the composite fiber sleeve along with a curable resin material to the tube. As the series of tubes having the cured composite sleeve thereon exits the apparatus, the tubes are severed at each of the joining plugs to produce a plurality of individual fiber reinforced tubular elements. Alternate methods of manufacturing the fiber reinforced tubular elements are also disclosed. In the preferred embodiment of the invention, the fiber reinforced tubular element is utilized as a vehicle drive shaft.
