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

exact text as granted — not AI-modified
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.
