A fiber reinforcement, which can be of solid or hollow construction, and a synthetic resin back up are disposed in a recess provided on the side of the club head remote from the shooting surface. A mass can be adjustably imbedded in the synthetic resin backup so as to increase the inertial moment of the club head. A rise member extending upwardly from the sole face of the club head can also be provided so that the center of gravity can be more easily adjusted. The fiber reinforcement is relatively thin for shorter shafted golf clubs having high degrees of loft, and increases progressively to a greater thickness for longer shafted golf clubs having relatively small degrees of loft. A back plate made of a woven cloth can be provided adjacent the fiber reinforcement to aid in reinforcing the shooting surface and to withstand the tension acting across the rear of the club head upon impact. The synthetic backup can be transparent or semi-transparent to expose the esthetics of the woven cloth. Bonding tape can be provided between the fiber reinforcement and the main body and between the fiber reinforcement and the back plate to facilitate the manufacture of the club head and to minimize the shock and vibration effect caused by striking a ball.
