<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a golf club shaft capable of improving the productivity and the quality by hardening a laminated body and facilitating polishing a braided layer, an object to be polished, in just proportion when using a braiding process. <P>SOLUTION: In this method of manufacturing the shaft, when base material fibers 3 impregnated with a resin material are braided on the periphery of a mandrel at a predetermined orientation angle with respect to a mandrel shaft direction and tapered cylindrical braided layers are sequentially superposed to form a tapered cylindrical laminated body 2, at least when the outermost peripheral third braided layer 2c is formed, the base material fibers 3 are braided by increasingly changing the orientation angle on the axial rear end side more than that of the axial end side, with defining the orientation angle a1 smaller than the orientation angle a2, and, after the formed laminated body 2 is heated and hardened, the surface of the laminated body 2 is polished at a fixed thickness. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
