Abstract

A golf club includes a head having a front body preferably made of metallic material and a rear body preferably made of non-metallic material. The front and rear bodies are constructed so that a crown wall on the metallic front body has a protruding section that mates with a recessed section of a crown wall on the rear body. The protruding section of the crown wall on the front body lies in a region of the club head that experiences the highest deflection and stress during impact with a golf ball. Therefore, the club head behaves, during impact with a golf ball, substantially as if the rear body were formed of metallic material rather than non--metallic material.
