ABSTRACT:
A golf club head with a composite body which in turn has a ceramic sponge body defining a number of pores therein and a filler selected from the group consisting of metals, synthetic resins, fiber-reinforced metals and fiber-reinforced resins and impregnated into the pores. The golf club head is fabricated by forming a foamed resin head substantially conforming in configurations and dimensions with the composite body, impregnating the foamed resin head with a ceramic slurry, followed by sintering to form a ceramic sponge body defining pores therein, filling the pores of the ceramic sponge body with a wax, covering the ceramic sponge body with a mold-forming refractory material, applying a heat treatment to remove the wax and to sinter the refractory material, and then casting the filler into the pores.
