Abstract
Golf club structures, including club heads and shafts, composed of composites comprised of a matrix of metal, such as an aluminum alloy, or a plastic material and a fiber such as graphite or a ceramic, which may be whiskerized, and which may also be selectively weighted as in the toe and heel of a club head, with heavy particles such as tungsten metal. The club structure may also be surface hardened by applying a coating of fullerenes to a metal club structure and heat treating it to produce a hard coating of metal carbide, preferably by coating a titanium golf club structure with fullerenes and heat treating the coated structure to produce a titanium carbide surface.
