ABSTRACT:
The present invention is directed to improved heads for golf clubs, including iron, wood and putter type golf club heads, and to methods of manufacturing such golf club heads. One or more layers of a loaded film are used to define in part the overall weight, center of gravity, and inertial characteristics of the golf club head, without significantly affecting the structural characteristics of the golf club head. A set of plies of pre-preg composite fiber sheet and one or more layers of loaded film are applied in a predetermined manner to a forming mold to make a preform. The preform is removed from the forming mold. One or more additional layers of densified loaded film may be applied to the preform, and the preform may be placed in a curing mold. In the case of wood type golf club heads, a bladder may be introduced into a hollow core of the preform. The bladder may be inflated, and the mold may be heated for a predetermined period of time. Alternatively, a dry reinforcement preform may be made on the forming mold from a set of plies of composite fiber and loaded film. Prior to heating the mold, resin is injected into the mold, providing a binding material for the composite fiber and loaded film comprising the preform.
