ABSTRACT:
An apparatus and method of using same to form tubular tapered shafts particularly adapted for golf clubs, ski poles, fishing rods and the like. The material used in forming the shafts is a thermo-setting resin sheet that has a number of elongate, laterally spaced, parallel fibers of graphite carbon, boron or like material therein, which fibers have a tensile strength comparable to steel, but are only a fraction of the weight of the latter. The apparatus and method of using the same is characterized by the tubular shaft being formed with exterior and interior cylindrical wall surfaces that are truly concentric, and with the fibers embedded in the polymerized resin being pre-tensioned and spaced from one another. The polymerized resin selected is one that effects a strong bond with the fibers, is more elastic than the material defining the fibers, and as a result the fibers absorbing the major portion of the load when the shaft is transversely flexed such as occurs when it is used as a component in golf clubs and fishing rods. The apparatus is susceptible to being used with other resin impregnated load receiving materials such as powders, fabrics, cloth and the like, but the resulting tubular tapered shafts do not have the strength and operational advantages of shafts that embody graphite carbon or boron fibers as a part thereof.
