Abstract

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 metallic-composite. The crown portion includes a strands of Nickel-plated polyethylene terephthalate fiber interwoven among carbon fibers.

Claims

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; and

the crown portion includes strands of Nickel-plated polyethylene terephthalate fiber interwoven among carbon fibers.

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.

4. The golf club head according to claim 1, wherein the first material is a stainless steel alloy.

5. The golf club head according to 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 body portion is forged.

7. The golf club head according to claim 1, wherein the body portion is sheet metal formed.

8. The golf club head according to claim 1, wherein the body portion is cast.

9. The golf club head according to claim 1, wherein the club head has a maximum coefficient of restitution greater than 0.80.

10. 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; and

the crown portion includes strands of Aluminum-plated polyethylene terephthalate fiber interwoven among carbon fibers.

11. The golf club head according to claim 10, wherein the crown portion density is between about 0.1 g/cc to 4.0 g/cc.

12. The golf club head according to claim 10, wherein the first material is a titanium alloy.

13. The golf club head according to claim 10, wherein the first material is a stainless steel alloy.

14. The golf club head according to claim 10, wherein the crown portion is cast, formed, injection molded, machined, or pre-preg sheet formed.

15. The golf club head according to claim 10, wherein the body portion is forged.

16. The golf club head according to claim 10, wherein the body portion is sheet metal formed.

17. The golf club head according to claim 10, wherein the body portion is cast.
