Abstract
A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. The golf club head includes a frontal portion and a rear portion formed of a thermoplastic composite material. The thermoplastic composite material is mechanically captured by at least one first attachment feature provided in the frontal portion such that the thermoplastic composite material may be joined to the frontal portion without the use of additional adhesives or external fasteners.
Claims13
A golf club comprised of a golf club head, a shaft having a shaft axis coupled to the golf club head at a first end of the shaft and a grip coupled to the shaft at a second end of the shaft, wherein the golf club head comprises:
- a frontal portion comprised of a first material having a first density, said frontal portion comprising a striking face having a face center located at a forward portion of said golf club head, a crown return at an upper portion of said frontal portion, a sole return at a lower portion of said frontal portion, and a rear circumferential attachment edge located at a rear of said frontal portion;
- and
- a rear portion comprised of a second material having a second density, said rear portion located aft of said striking face comprising a crown at an upper portion of said rear portion, a sole on a bottom portion of said rear portion, and a front circumferential attachment edge at a front portion of said rear portion, wherein said second material comprises a thermoplastic composite material;
- wherein at least one first attachment feature is defined on said rear circumferential attachment edge,
- wherein said front circumferential attachment edge comprises at least one second attachment feature that is coupled with said at least one first attachment feature to mechanically lock said rear portion to said frontal portion;
- wherein said first attachment feature comprises at least one undercut defined in an intermediate metallic scrim layer,
- wherein said intermediate metallic scrim layer is attached to said rear circumferential attachment edge via an adhesive, and
- wherein said rear portion is joined to said intermediate metallic scrim layer with no additional adhesives and no external fasteners.
