First Claim
Patent Images
1. A golf club head comprising:
- a hollow unitary shell, made out of a first material having a first density, forming at least one opening near a frontal portion of said golf club head;
at least one composite laminate, configured to engage said at least one opening said at least one composite laminate including a striking face layer;
wherein said at least one composite laminate further comprises a plurality of composite strand lamina layers and at least one of a carbon nanotube lamina layer,wherein said at least one composite laminate has an interlaminar shear strength of between about 60 MPa to about 145 MPa, andwherein said at least one of said carbon nanotube lamina layer comprises fibers that are all substantially parallel to each other and substantially perpendicular to said striking face layer.

Abstract
A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face that forms a pocket, wherein the pocket is filled with a secondary material having a lower density to improve the performance of the golf club head. The multi-material face disclosed in accordance with the present invention may generally have an inter laminar shear strength of greater than about 60 MPa, most preferably greater than about 60 MPa and less than about 145 MPa.
