<p>PROBLEM TO BE SOLVED: To provide a lightweight shaft for a golf club while retaining rigidity by forming the shaft for a golf club formed by laminating two or more fiber- reinforced plastic layers having an angle layer and a straight layer, wherein the angle layer is molded from a prepreg sheet of a specified thickness for specifying a weight of the entire shaft. SOLUTION: A shaft for golf club is formed by laminating two or more fiber-reinforced plastic layers and providing an angle layer and a straight layer. The angle layer is molded from a prepreg sheet having 0.020-0.095 mm thickness and a weight of the entire shaft for golf club is in a range of 30-55 g. A reinforcing fiber of a prepreg sheet for molding the angle layer has a fiber weight of preferably 20-95 g/m2. A reinforcing fiber for forming the fiber-reinforced plastic layer is not specifically specified, however an organic reinforcing fiber such as a para-type aromatic polyamide, a high-strength polyethylene or the like, a carbon fiber or a glass fiber is preferable.</p> |
