Multi-material golf clubhead

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 also comprise a variously configured and/or 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.

       6 . A golf club head in accordance with  claim 1 , wherein said tuning insert comprises a damping mechanism. 
   
   
       7 . A golf club head in accordance with  claim 1 , further comprising a tuning weight attached to an interior surface of said body structure. 
   
   
       8 . A golf club head in accordance with  claim 7 , wherein said tuning weight provides for an adjustable center of gravity. 
   
   
       9 . A golf club head in accordance with  claim 7 , wherein said tuning weight provides for an adjustable moment of inertia. 
   
   
       10 . A golf club head in accordance with  claim 1 , wherein said faceplate has a centrally located depression. 
   
   
       11 . A golf club head in accordance with  claim 1 , wherein said faceplate has an undulating depression. 
   
   
       12 . A golf club head in accordance with  claim 1 , wherein said faceplate has a stepped depression. 
   
   
       13 . A golf club head in accordance with  claim 1 , wherein said faceplate has a predetermined acoustic profile. 
   
   
       14 . A golf club head, comprising:
 a body structure having a faceplate aperture;   a faceplate with a varying thickness;   a fastening mechanism for fastening said faceplate to said body structure; and   wherein said faceplate aperture further comprising a faceplate receiving area upon which said faceplate is retained on said body frame structure and a tuning insert between said body structure and said faceplate.   
   
   
       15 . A golf club head in accordance with  claim 14 , wherein said fastening mechanism comprises removable and re-attachable fasteners. 
   
   
       16 . A golf club head in accordance with  claim 14 , wherein said fastening mechanism is a laterally extending screw. 
   
   
       17 . A golf club head in accordance with  claim 14 , wherein said fastening mechanism is a key mechanism. 
   
   
       18 . A golf club head in accordance with  claim 14 , further comprising a tuning weight attached to an interior surface of said body structure. 
   
   
       19 . A golf club head in accordance with  claim 14 , wherein said tuning insert comprises a damping mechanism. 
   
   
       20 . A golf club head in accordance with  claim 14 , wherein said faceplate has at least one of a centrally located depression, an undulating depression, and a stepped depression. 
   
   
       21 . A golf club head in accordance with  claim 14 , wherein said faceplate has a predetermined acoustic profile. 
   
   
       22 . A golf club head, comprising:
 a body structure having a faceplate aperture;   a tuning weight inside the golf club head;   a faceplate with at least one of a centrally located depression, an undulating depression, and a stepped depression; and   removable and re-attachable fasteners for fastening said faceplate to said body structure; and wherein said faceplate aperture further comprising a faceplate receiving area upon which said faceplate is retained on said body frame structure and a tuning insert between said body structure and said faceplate.
