A method for producing a composite golf club head includes the steps of forming a metal hollow casing; disposing a bowl-shaped laminated member in the metal hollow casing; providing an expansible pocket in the bowl-shaped laminated member, the expansible pocket containing a mixture of sodium nitrite, ammonium chloride and water; disposing a sheet of carbon fiber composite material over an open top portion of the metal hollow casing, in order to close the open top portion of the metal hollow casing and the open end of the bowl-shaped laminated member; disposing the metal hollow casing in a mold; and heating the mold to a temperature of 140 DEG -160 DEG C., in order to allow the mixture in the expansible pocket to react and produce nitrogen gas in the expansible pocket, thereby swelling the expansible pocket and forcing the bowl-shaped laminated member to attach to the metal hollow casing, and allowing the sheet of carbon fiber composite material and the bowl-shaped laminated member to harden and connect integrally to each other. |
