Composite metal wood club
View Patent ↗A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion and a crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The material for the crown portion is preferably a composite. A vibration dampening gasket is disposed between the ledge and lip sections of the body and crown respectively.
1. A golf club head comprising:
a body portion and a crown portion;
the body portion is composed of a first material having a density;
the crown portion is composed of a second material having a density that is less than the density of the first material;
the body portion having a ledge section formed therein;
the crown portion having a lip section formed therein; and
a shock absorbing gasket disposed between the ledge section and the lip section,
wherein, shock absorbing gasket produces a reduction in noise of at least 28 percent over a frequency range between about 3800 Hz to 10,000 Hz at a swing speed of 90 mph.
2. The golf club head according to claim 1 , wherein the crown portion density is between about 0.1 g/cc to 4.0 g/cc.
3. The golf club head according to claim 1 , wherein the first material is a titanium alloy and the second material is a composite or a thermoplastic or a metal.
4. The golf club head according to claim 1 , wherein the first material is a stainless steel alloy and the second material is a metal, a composite or a thermoplastic.
5. The golf club head of claim 1 , wherein the crown portion is cast, formed, injection molded, machined or pre-preg sheet formed.
6. The golf club head according to claim 1 , wherein the second material is a composite.
7. The golf club head of claim 1 , wherein the body portion is forged.
8. The golf club head of claim 1 , wherein the body portion is sheet metal formed.
9. The golf club head of claim 1 , wherein the body portion is cast.
10. The golf club head according to claim 1 , wherein the club head has a maximum coefficient of restitution greater than 0.80.
11. The golf club head of claim 1 , wherein the gasket is composed of a titanium mesh.
12. The golf club head of claim 1 , wherein the gasket is composed of aluminum foil material.
13. The golf club head of claim 1 , wherein the gasket is composed of a viscoelastic material.
