ABSTRACT:
A wood-type golf club head containing a fiber reinforced plastic outer shell formed by heat pressing in a mould, around an intermediate shell. A solid center core is formed inside the intermediate shell by injection of foam synthetic resin for reduced generation of harsh and keen noises at hitting balls, ideal transmission of striking energy to balls and high durability against shocks by hitting balls. The elastic modulus of the outer shell material is greater than that of the intermediate shell material. The buckling strength of the intermediate shell material is greater than that of the foam resin core material.
