GOLF CLUB HEAD MADE OF CARBON FIBER-REINFORCED THERMOPLASTIC RESIN

摘要

PURPOSE:To obtain a golf club with high elasticity and excellent productivity by using a small complex cut from a fiber-reinforced thermoplastic resin complex to a specific length. CONSTITUTION:A fiber-reinforced thermoplastic resin complex reinforced with long-fiber-shaped carbon fibers with the elasticity 30t/mm<2> or above is cut into small complexes to the reinforcing fiber direction length of 3-25mm, the small complexes are collected to obtain the aggregate of the complexes with the fiber content of 20-65wt.% and the aggregate is heated and molded. Small complexes cut from the carbon fiber-reinforced thermoplastic resin complex arranged and converged in the longitudinal direction are used as a molding raw material, and a lightweight club head with sufficient rigidity can be obtained when the fiber-reinforced thermoplastic resin reinforced with high- elasticity carbon fibers is used.
