Composite metal wood club
View Patent ↗A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion composed of titanium alloy and a graphite 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 body portion has an attachment ledge section and the crown portion has attachment section that overlays the attachment section of the body. A vibration dampening gasket is disposed between the attachment sections.
1. A golf club head comprising:
a body portion and a crown portion;
the body portion is composed of a composite material having a density that is less than the density of the titanium alloy;
the crown portion is composed of a composite material having a density that is less than the density of the titanium alloy;
the body portion having an attachment ledge section;
the crown portion having an attachment section formed to overlay the attachment ledge section of the body portion; and
a shock absorbing gasket disposed between the attachment sections,
wherein said 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 club head 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 of claim 1 , wherein the crown portion is pre-preg sheet formed.
4. The golf club head according to claim 1 , wherein the composite material is graphite.
5. The golf club head of claim 1 , wherein a portion of the body portion is forged.
6. The golf club head of claim 1 , wherein a portion of the body portion is metal formed.
7. The golf club head of claim 1 , wherein a portion of the body portion is cast.
8. The golf club head according to claim 1 , wherein the club head has a maximum coefficient of restitution greater than 0.80.
9. The golf club head of claim 1 , wherein the gasket is composed of a titanium mesh.
10. The golf club head of claim 1 , wherein the gasket is composed of aluminum foil material.
11. The golf club head of claim 1 , wherein the gasket is composed of a viscoelastic material.
