Metal wood club with improved hitting face
First Claim
1. A golf club head comprising:
- a hitting face having a face insert coupled around a perimeter thereof to the golf club head, the hitting face comprising a central zone insert comprising a first material, and a second zone,wherein the second zone is concentric with the central zone insert and attached to the central zone insert around a perimeter thereof,wherein the second zone comprises a second material different than the first material, andwherein the second material has a lower yield strength than the first material and the dimensions of the central zone insert and the second zone are selected such that the second zone plastically deforms while the central zone insert elastically deforms due to the impact force of striking a golf ball.

Abstract
A hitting face of a golf club head having improved flexural stiffness properties. In one embodiment, the hitting face is made from multiple materials. Each material has a different tensile modulus of elasticity, where the center of the hitting face has a much higher tensile modulus of elasticity than the surrounding portions of the hitting face. This creates a stiff center and a more easily deflected concentric portion. In another embodiment, the materials have different yield strengths, where the center of the hitting face has a very high yield strength compared to the surrounding portions of the hitting face. The hitting face may then plastically deform around its periphery, while the center retains its original shape.
