A golf club head including a lightweight composite material molded to a hard, high density material to provide selected distribution and localization of mass within the golf club head. The lightweight composite material provides desirable properties of strength and stiffness to the club head hosel and blade portions while the hard, high density material provides necessary club weight, mass distribution, structure and shape. The use of lightweight composite material in combination with high density material allows placement of the club mass substantially entirely in the blade or head portion to provide enhanced energy transfer. Club heads utilizing ceramic fiber and/or ceramic particles are also disclosed. The club head may include a central foam core surrounded by a rigid shell including resin impregnated fibers and ceramic particles dispersed in the resin.
A golf club head comprising a rigid club head shell wherein said shell comprises resin impregnated fibers and ceramic particles dispersed in said resin.
