Patent Images
1. A method for forming a macrocomposite golf club head comprising the steps of:
- providing a first mass of substantial nonreactive filler material in the shape of a golf club head, said first mass having a receiving surface for receiving a golf club insert;
infiltrating substantially completely said first mass of filler material with an oxidation reaction product of a parent metal and at least one oxidant to form a ceramic matrix composite golf club head having a receiving surface for a golf club insert;
providing a second mass of substantially nonreactive filler material in the shape of a golf club insert;
spontaneously infiltrating with molten matrix metal said second mass of filler material to form a metal matrix composite golf club insert; and
placing said metal matrix composite insert into contact with said receiving surface of said ceramic matrix composite golf club head and, utilizing a fastening said, fastening together said metal matrix composite insert and said ceramic matrix composite golf club head to produce a macrocomposite golf club head.
