Abstract
A forged golf club face has a continuous outer layer of a first material encasing at least one inner layer made of second material. The materials may have differing properties, such as Young's Modulus, density, and strength properties, among others. By incorporating the different materials into the outer layer and the inner layer, the coefficient of restitution (COR) of the golf club face is improved without sacrificing durability. The club face is forged from a pre-formed billet having at least one monolithically encased inner layer.
Claims20
A golf club head comprising:
- a sole;
- and
- a forged multi-material striking face attached to at least a portion of the sole, the forged multi-material striking face comprising:
- a continuous outer layer made of a first material;
- and
- an inner layer made of a second material, the inner layer being fully encased by the continuous outer layer, wherein the inner layer is substantially centered within the continuous outer layer and wherein the first material is a titanium-based material that has a lower Young's modulus than a Young's modulus of the second material.
A golf club head comprising:
- a forged multi-material striking face, the striking face comprising:
- a continuous outer layer made of a first material;
- a continuous middle layer made of a second material, the continuous middle layer being fully encased by the continuous outer layer;
- and
- an inner layer made of a third material, the inner layer being fully encased by the continuous middle layer, wherein the third material displays a lower Young's modulus than a Young's modulus of the second material.
A forged multi-material striking face, comprising:
- a continuous outer layer made of a first material;
- and
- an inner layer made of a second material, the inner layer being fully encased by the continuous outer layer, wherein the inner layer is substantially centered within the continuous outer layer and wherein the first material is a titanium-based material that has a lower Young's modulus than a Young's modulus of the second material.
