1. A golf club head comprising:
- a shell made of a composite material that is attached to a strike plate formed of a metallic material, the shell including a first mating section and the strike plate including a second mating section configured to mate with the first mating section and a hosel formed of a metallic material extends outward from the strike plate;
wherein the first mating section defines an opening at a front and bottom of the shell, the opening extending rearwardly along a perimeter of the club head adjacent to a rear of the club head, and the second mating section is at least four times as wide as a thickness of the shell;
wherein the first mating section overlaps the second mating section along a perimeter of the club head adjacent to the rear of the club head;
wherein the first mating section includes a first attachment surface that faces inward and the second mating section includes a second attachment surface that faces outward; and
wherein the shell has an inner surface that is smooth.

Abstract
A method for forming a golf club head comprises placing an uncured composite material between a core and a mold that comprises a first piece and a second piece. The second piece is moved towards the first piece such that the uncured composite material is compressed between the core and at least a portion of the mold. The uncured composite material is heated. A first portion of the golf club head is removed from the mold. A second portion of the golf club head is provided. The first portion is attached to the second portion. In certain arrangements, the second portion is formed from a metallic material.

13. A golf club head comprising:
-
a shell made of a composite material that is attached to a strike/sole plate combination that includes a strike plate and a sole plate which are integrally formed and made of a metallic material, the shell including a first mating section and the strike/sole plate combination including a second mating section configured to mate with the first mating section; wherein the strike/sole plate combination comprises a hosel that extends outward from the strike/sole plate combination and the shell comprises a toe side wall and a heel side wall that extend downward to the sole plate and form toe and heel portions of the club head; wherein the shell includes an outer surface, an inner surface, and a first abutment surface formed as a portion of the first mating section and extending between the outer and inner facing surfaces of the shell; wherein the second mating section includes a second abutment surface and the second mating section is at least four times as wide as a thickness of the shell; wherein the first mating section includes a first attachment surface that faces inward and the second mating section includes a second attachment surface that faces outward; and wherein the inner surface of the shell is smooth. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A golf club head comprising:
-
a shell made of a composite material that is attached to a strike plate that is formed of a metallic material; wherein the strike plate includes a face portion, a sole plate portion connected to the face portion, a crown portion connected to the face portion, and a hosel that extends outward from the strike plate; wherein the shell includes a first mating section adjacent the crown portion and the strike plate includes a second mating section that is part of the crown portion and that mates with the first mating section and forms interlocking steps that couple the shell and the strike plate together; wherein the first mating section of the shell comprises a first abutment surface and a third abutment surface, the first abutment surface extending inwardly from an outer surface of the shell and the third abutment surface extending outwardly from an inner surface of the shell, the first and third abutment surfaces being offset and spaced apart by a first attachment surface of the first mating section that extends from an inner end of the first abutment surface to an outer end of the third abutment surface, the first attachment surface being positioned between the outer and inner surfaces of the shell; wherein the second mating section of the strike plate comprises a second abutment surface and a fourth abutment surface, the second abutment surface extending inwardly from an outer surface of the strike plate and the fourth abutment surface extending outwardly from an inner surface of the strike plate, the second and fourth abutment surfaces being offset and spaced apart by a second attachment surface of the first mating section that extends from an inner end of the first abutment surface to an outer end of the second abutment surface, the second attachment surface being positioned between the outer and inner surfaces of the strike plate; wherein the first abutment surface abuts the second abutment surface, the second abutment surface abuts the fourth abutment surface, and the first attachment surface abuts the second attachment surface, such that the first and second mating sections form the interlocking steps; wherein the first attachment surface is at least four times as wide as a thickness of the shell; wherein the first attachment surface faces inward and the second attachment surface faces outward; and wherein the shell has an inner surface that is smooth. - View Dependent Claims (23, 24, 25, 26)
