Multi-material golf club head

Abstract

A golf club head in accordance with various aspects of the present invention, may have a higher volume and/or higher strength. The golf club head may comprise a frame structure with a composite matrix. The golf club head may also comprise a detachable face, allowing various faces of differing materials to be attached to the body. A detachable face further allows the head to be tuned via placement/rearrangement of weights within the head to change the center of gravity and moment of inertia.

1 . A golf club head, comprising: 
 a body combination having a body frame structure defining an outer surface of the golf club head and encompassing a filler matrix in contact with an inner surface of said body frame structure;    a faceplate; and wherein    said body frame structure having a faceplate aperture further comprising a perimeter substantially coincident with said faceplate, said faceplate aperture further comprising a faceplate receiving ridge upon which said faceplate is retained on said body frame structure.    
   
   
       2 . A golf club head in accordance with  claim 1 , further comprising a fastening mechanism for fastening said faceplate to one of said frame structure and said filler matrix.  
   
   
       3 . A golf club head in accordance with  claim 2 , further comprising a coolant system and wherein said fastening mechanism comprises a weld.  
   
   
       4 . A golf club head in accordance with  claim 2 , wherein said fastening mechanism comprises removable and re-attachable fasteners.  
   
   
       5 . A golf club head in accordance with  claim 1 , further comprising a tuning weight attached to an interior surface of said body combination.  
   
   
       6 . A golf club head in accordance with  claim 5 , wherein said tuning weight provides for an adjustable center of gravity.  
   
   
       7 . A golf club head in accordance with  claim 5 , wherein said tuning weight provides for an adjustable moment of inertia.  
   
   
       8 . A golf club head, comprising: 
 a body combination having a body frame structure defining an outer surface of the golf club head and at least one aperture and a filler matrix which fills an area defined by said aperture;    a faceplate; and wherein    said body frame structure further comprises a faceplate aperture having a perimeter substantially contiguous with said faceplate and a faceplate receiving ridge upon which said faceplate is retained on said body frame structure.    
   
   
       9 . A golf club head in accordance with  claim 8 , further comprising a fastening mechanism for fastening said faceplate to said body frame structure.  
   
   
       10 . A golf club head in accordance with  claim 9 , wherein said fastening mechanism comprises removable and re-attachable fasteners.  
   
   
       11 . A golf club head in accordance with  claim 9 , further comprising a coolant system and wherein said fastening mechanism comprises a weld.  
   
   
       12 . A golf club head in accordance with  claim 8 , further comprising a tuning weight attached to an interior surface of said body combination.  
   
   
       13 . A golf club head, comprising a body frame having a faceplate aperture having a perimeter substantially contiguous with a faceplate and a faceplate receiving ridge upon which said faceplate is retained on said body frame structure, said faceplate removably attachable to said faceplate receiving ridge with a fastening mechanism.  
   
   
       14 . A golf club head in accordance with  claim 13 , wherein said fastening mechanism comprises screws threaded into said faceplate receiving ridge.  
   
   
       15 . A golf club head in accordance with  claim 14 , wherein said body comprises a body frame structure and filler matrix combination.  
   
   
       16 . A golf club head in accordance with  claim 15 , further comprising a tuning weight attached to an interior surface of said body combination.  
   
   
       17 . A golf club head assembly, comprising: 
 a faceplate;    a body combination having 
 a body frame structure defining an outer surface of the golf club head, and  
 at least one aperture with a filler matrix which fills an area defined by said aperture;  
   said body frame structure further comprising a faceplate aperture having a perimeter substantially contiguous with said faceplate and configured to receive said faceplate; and    a cooling system proximate to an area where said faceplate and said body frame structure meet to reduce the amount of heat transferred to said filler matrix during a welding operation to attach said faceplate to body frame structure.    
   
   
       18 . A golf club head in accordance with  claim 17 , wherein said cooling system is a heat sink.  
   
   
       19 . A golf club head in accordance with  claim 17 , wherein said cooling system is a liquid bath.  
   
   
       20 . A golf club head in accordance with  claim 17 , further comprising a tuning weight attached to an interior surface of said body combination.
