<p>PURPOSE:To provide the golf club shaft made of a fiber reinforced composite resin material which is light in weight, is improved in mechanical strength, such as torsional fracture strength, and is further improved in impact resistance and the touch at the time of use. CONSTITUTION:A composite layer 1' laminated with a fiber reinforced composite resin material layer, a resin film layer and a metallic film layer is provided between an angle layer 101' and straight layer 102' of the golf club shaft. Since the composite layer 1' has the resin film layer and the metallic foil layer, the shaft is light in weight and is improved in the mechanical strength, such as torsional fracture strength; further, the impact resistance is improved as well and the touch at the time of use is good.</p> |
