A golf club having a hollow head (10) is filled with a filling material formed with a multiplicity of blind bores (18). The bores are spaced apart in the filling material, and the open ends of the bores normally are covered by an insert (14a) which forms the striking surface of the golf club head. The insert is detachable from the hollow head to permit access to the open ends of the blind bores. The blind bores can receive weights to achieve a desired weight and balance of the hollow head. The weights are removable when the insert is detached from the hollow head. The front ball striking surface of the insert is defined by a layer of woven plastic impregnated with a liquid plastic material, such as epoxy resin. The rear surface of the insert includes a layer of compacted, folded strands or ribbons of carbon fiber. When a foam filling material is injected into the hollow club head, the foam will reach and penetrate interstices of the folded carbon strands. |
