Golf club head and process for making the same

Abstract

In a process for making a golf club head, an open hollow body is formed from metal to define a front striking panel, a bottom panel and a hollow neck section of the golf club head. The bottom panel extends rearwardly from a bottom end of the striking panel. The neck section is connected to the striking and bottom panels. A moldable closed hollow body is formed using a resin-impregnated fiber sheet material, and is positioned inside the open hollow body. An air bag is placed inside the closed hollow body. The open and closed hollow bodies are subsequently placed in a mold. The mold is heated, and air is blown into the air bag so as to pressurize the closed hollow body against inner surfaces of the open hollow body and the mold until the resin-impregnated fiber sheet material is cured.

1 . A golf club head, comprising: 
 an open hollow body made of light metal, the open hollow body comprises an upper opening, a front striking panel and a bottom panel extended rearwards from a bottom of the front striking plate;    a carbon fiber top cover mounted on the upper opening of the open hollow body to form an integral composite sectional club head; and    wherein total weight of the composite sectional club head is relatively light due to the carbon fiber top cover.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein the carbon fiber top cover comprises a combined top wall and a lateral wall member.  
   
   
       3 . The golf club head as claimed in  claim 1 , wherein the carbon fiber top cover is made of a resin-impregnated fiber sheet.  
   
   
       4 . The golf club head as claimed in  claim 1 , wherein the open hollow body further comprises a hollow neck section attached thereto.  
   
   
       5 . The golf club head as claimed in  claim 1 , wherein the open hollow body is made of titanium alloy.  
   
   
       6 . The golf club head as claimed in  claim 1 , further comprising a resin-impregnated fiber strip inserted into a corner space defined by a flanged end of the front striking panel.
