GOLF SHAFT AND MANUFACTURING METHOD THEREOF TO INCREASE SWING SPEED BY AGGLUTINATING METAL COVER TO EXTERIOR OF COMPOSITE MATERIAL SHAFT

摘要

PURPOSE: A golf shaft and manufacturing method thereof are provided to increase swing speed by agglutinating a metal cover, on which uneven portion or minute channels are formed, to the exterior of a composite material shaft with a bonding agent. CONSTITUTION: The golf shaft includes a composite material shaft within and a metal cover(10), which sticks to the exterior of the composite material shaft. The composite material(20) is lighter than a metal material, and has great strength and hardness. Uneven portions or minute channels in the axial direction are formed in the exterior of the metal cover. The thickness of the metal cover is less than 0.2mm. The metal cover is made of any one of titanium, zinc, stainless steel, aluminum, and anodizing aluminum.
