摘要： A golf club shaft and a golf club using such a golf club shaft are achieved in which the isotropy of the prepregs configuring a torsion rigidity holding layer is high and in which sufficient torsional rigidity can be secured with a lesser number of plies of prepregs.The golf club shaft is characterized by a torsional rigidity holding layer made of a thermosetting resin which contains reinforced fibers extending obliquely to a longitudinal direction of the shaft. The torsional rigidity holding layer includes a multilayer set prepreg, in which at least two layers of prepregs made of reinforced fibers are impregnated with a thermosetting resin. A plurality of prepregs in the multilayer set prepreg include reinforced fibers extending in mutually different directions; and the multilayer set prepreg is continuously wound by at least two turns with the plurality of prepregs layered on each other.

摘要： A golf club shaft in which the isotropy of the prepregs configuring a torsion rigidity holding layer is high and in which sufficient torsional rigidity can be secured with fewer plies of fewer prepregs. The golf club shaft includes a torsional rigidity holding layer made of a thermosetting resin which contains reinforced fibers extending obliquely to a longitudinal direction of the shaft. The torsional rigidity holding layer includes a multilayer set prepreg, in which at least two layers of prepregs made of reinforced fibers are impregnated with a thermosetting resin. A plurality of prepregs in the multilayer set prepreg include reinforced fibers extending in mutually different directions. The multilayer set prepreg is continuously wound by at least two turns with the plurality of prepregs layered on each other. A golf club uses the shaft.
