Method for manufacturing and golf club head
View Patent ↗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.
1. 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, the shell including a first mating section and the strike plate including a second mating section configured to mate with the first mating section;
wherein the strike plate includes a face portion, a sole plate portion coupled to the face portion, and a crown portion coupled to the face portion, the face portion and the sole plate portion and the crown portion comprising titanium;
wherein the crown portion has an outwardly facing attachment surface generally between an outer surface and an inner surface of the crown portion and a first abutment surface extending between the attachment surface and the outer surface of the crown portion, wherein the attachment surface defines a crown opening;
wherein the shell comprises carbon fiber reinforced epoxy and is coupled to the attachment surface, the shell having an outer surface, an inner surface, and a second abutment surface extending between the outer and inner facing surfaces of the shell; and
wherein the attachment surface is bonded to the inner surface of the shell, the first abutment surface is connected to the second abutment surface, and the attachment surface is at least four times as wide as a thickness of the shell.
2. The golf club head of claim 1 , wherein the first mating section and the second mating section extend entirely along an interface between the shell and the strike plate.
3. The golf club head of claim 1 , wherein the first mating section includes a first abutment surface, which is transverse to an outer surface of the shell and the second mating section includes a second abutment surface, which is substantially parallel to the first abutment surface.
4. The golf club head of claim 1 , wherein the first mating section includes a first attachment surface, which is generally parallel to an outer surface of the shell and the second mating section includes a second attachment surface, which is substantially parallel to the first attachment surface.
5. The golf club head of claim 1 , wherein the first mating section includes a first abutment surface, which is transverse to an outer surface of the shell and a first attachment surface, which is generally parallel to an outer surface of the first portion and the second mating section includes a second abutment surface that is substantially parallel to the first abutment surface and a second attachment surface that is substantially parallel to the first attachment surface.
6. The golf club head of claim 1 , wherein adhesive secures the first mating section to the second mating section.
7. The golf club head of claim 1 , wherein adhesive secures the first mating section to the second mating section.
8. The golf club head of claim 1 , wherein the first mating section overlaps and is external to the second mating section.
9. The golf club head of claim 1 , wherein the sole plate portion includes a rib that protrudes inwardly from a periphery of the sole plate portion into an interior of the golf club head.
