Abstract
A golf club head (20) having a striking plate (30) and means for vibration attenuation (35) disposed thereon. The vibration attenuation means (35) may be composed of a low-density. metallic, a polymer material, or a filled polymer material. The striking plate (30) may have a uniform thickness or a variable thickness. The overall thickness of the striking plate (30) and vibration attenuation means (35) is preferably in the range of 0.100 inch to 0.250 inch. The striking plate (30) is preferably composed of steel or titanium.
Claims12
A golf club head comprising:
- a body having a crown, a sole, a heel end, a toe end and a hollow interior;
- a striking plate attached to the body, the striking plate having an exterior surface and an interior surface, the striking plate having a thickness that varies from 0.030 inch to 0.250 inch;
- and
- a vibration attenuation backing disposed on the interior surface of the striking plate within the hollow interior of the body, the combination of the striking plate and the vibration attenuation backing having a minimum thickness of at least 0.100 inch at any point between the exterior surface of the striking plate and the hollow interior;
- wherein the striking plate and vibration attenuation backing are composed of materials that satisfy the following equation:
- 0.90 ⟨ E 35 E 30 ρ 30 ρ 35 ⟨ 1.10 and 0.90 ⟨ G 35 G 30 ρ 30 ρ 35 ⟨ 1.10
- wherein E35, G35, and 35 are the material compression stiffness, shear stiffness, and density, respectively, for the vibration attenuation backing, and E30, G30, and 30 are the material compression stiffness, shear stiffness, and density, respectively, for the striking plate.
