Golf club shaft and golf club

Abstract

A golf club shaft is formed by curing wound fiber-containing prepregs and has a tip side and a butt side. In an embodiment, the prepregs include pitch-based carbon fiber-containing prepregs with a low elastic modulus, which are wound on the tip side, and polyacrylonitrile (PAN) based carbon fiber-containing prepregs, which are wound in an outermost layer on the tip side. In another embodiment, the prepregs include low-elasticity carbon fiber-containing prepregs wound on the tip side, and high-elasticity carbon fiber-containing prepregs wound on the butt side. In yet another embodiment, the prepregs include low-elasticity carbon-containing prepregs, which are wound on the butt side, and high elasticity carbon-containing prepregs, which are wound on the tip side.
