  • Patent number: 6354960
    Abstract: A golf club shaft is formed with an elongated body using a combination of fiber-reinforced plastics and metal-coated fibers to obtain the optimally characterized golf club for a particular player. In one embodiment, a sheet-rolled or filament wound core is covered by a filament wound outer layer having at least one ply including metal-coated fibers. The fibers can be metal-coated with metals such as: nickel, titanium, platinum, zinc, copper, brass, tungsten, cobalt, gold or silver. The use of metal-coated fibers allows the use of combinations of fiber reinforced plastic and metal-coated fibers in producing golf shafts with optimum performance properties. For example, the use of metal-coated fibers allows the addition of weight to the shaft without significantly influencing its longitudinal or torsional rigidity.
