  • Patent number: 5601892
    Abstract: Hollow rods are formed with at least one inner ply of graphite fibers in a first thermoset resin matrix and at least one outer ply of nickel-coated graphite fibers in a second thermoset resin. An outermost protective ply may be added to protect the integrity of the nickel-coated graphite fibers through the finish grinding steps. The nickel-coated graphite fibers impart increased impact strength to the final structure and serve to protect the inner graphite fiber layer(s) by preventing crack propagation that would lead to failure of the composite. The rods may be formed into suitable shapes for fishing rods, golf shafts, and arrow shafts.
