Golf club head and composite plate therefor

Abstract

A golf club head includes a golf club head body made of metal and having a striking plate, at least one recession defined in the golf club head body, and at least one composite plate engaged in the recession to form a portion of a shell of a golf club head product. The composite plate includes at least one metal layer and at least one non-metal layer that are laminated by pressing. The adjusting ranges of the center of gravity and of the striking sound of the golf club head are increased.

       5 . The golf club head as claimed in  claim 1 , wherein said at least one composite plate includes in sequence a first non-metal layer, a metal layer, a second non-metal layer, and a third non-metal layer.  
   
   
       6 . The golf club head as claimed in  claim 5 , wherein the first non-metal layer is one of a uni-direction fabric, a plainwoven fabric, and a twilled fabric made of graphite, wherein the second non-metal layer is an adhesive layer of one of solvent-release type, pressure-sensitive type, heat-sensitive type, chemically-reactive type, and epoxy, and wherein the third non-metal layer is a single layer of impregnated graphite fabric.  
   
   
       7 . The golf club head as claimed in  claim 1 , wherein said at least one composite plate includes in sequence a metal layer, a first non-metal layer, and a second non-metal layer.  
   
   
       8 . The golf club head as claimed in  claim 7 , wherein the first non-metal layer is an adhesive layer of one of solvent-release type, pressure-sensitive type, heat-sensitive type, chemically-reactive type, and epoxy, and wherein the second non-metal layer is a single layer of impregnated graphite fabric.  
   
   
       9 . The golf club head as claimed in  claim 1 , wherein said at least one composite plate includes in sequence a composite layer, a metal layer, a first non-metal layer, and a second non-metal layer.  
   
   
       10 . The golf club head as claimed in  claim 9 , wherein the composite layer is a net formed by means of mix-weaving metal filaments and non-metal fibers, the metal filaments and the non-metal fibers being selected from the group consisting of graphite, Kevlar fibers, and titanium filaments, the first non-metal layer being an adhesive layer of one of solvent-release type, pressure-sensitive type, heat-sensitive type, chemically-reactive type, and epoxy, and the second non-metal layer being a single layer of impregnated graphite fabric.  
   
   
       11 . The golf club head as claimed in  claim 1 , wherein said at least one recession is defined in one of a crown portion, a sole portion, and a side portion of the golf club head body.  
   
   
       12 . The golf club head as claimed in  claim 1 , further including a buffering space defined between an inner periphery of said at least one recession and an outer periphery of said at least one composite plate, and a filler being filled in the buffering space.  
   
   
       13 . A composite plate for a golf club head, the composite plate comprising: 
 at least one metal layer; and    at least one non-metal layer, said at least one metal layer and said at least one non-metal layer being laminated by pressing to form the composite plate, the composite plate being adapted to be engaged in a recession of a golf club head to form a portion of a shell of the golf club head.    
   
   
       14 . The composite plate as claimed in  claim 13 , wherein said at least one non-metal layer is an outermost layer of the composite plate.  
   
   
       15 . The composite plate as claimed in  claim 13 , wherein said at least one metal layer is an outermost layer of the composite plate.  
   
   
       16 . The composite plate as claimed in  claim 13 , wherein said at least one metal layer has a density smaller than 4.8 g/cm 3  and is made of one of a light metal and an alloy.  
   
   
       17 . The composite plate as claimed in  claim 13 , wherein the composite plate includes in sequence a first non-metal layer, a metal layer, a second non-metal layer, and a third non-metal layer.  
   
   
       18 . The composite plate as claimed in  claim 17 , wherein the first non-metal layer is one of a uni-direction fabric, a plainwoven fabric, and a twilled fabric made of graphite, wherein the second non-metal layer is an adhesive layer of one of solvent-release type, pressure-sensitive type, heat-sensitive type, chemically-reactive type, and epoxy, and wherein the third non-metal layer is a single layer of impregnated graphite fabric.  
   
   
       19 . The composite plate as claimed in  claim 13 , wherein the composite plate includes in sequence a metal layer, a first non-metal layer, and a second non-metal layer.
