Golf club shaft

Abstract

A golf club shaft having a fiber reinforced thermosetting resinous material ( 10 ) and a fiber reinforced thermoplastic resinous material ( 20 ), wherein the fiber reinforced thermoplastic resinous material ( 20 ) having a vibration-damping factor not less than 1.0 has a weight not less than 10% nor more than 60% of a weight of the golf club shaft. The fiber reinforced thermoplastic resinous material ( 20 ) is disposed on a part of a peripheral surface of the golf club shaft, on an inner peripheral surface thereof or between layers of the fiber reinforced thermosetting resinous material ( 10 ).

1 . A golf club shaft having a fiber reinforced thermosetting resinous material and a fiber reinforced thermoplastic resinous material, wherein the fiber reinforced thermoplastic resinous material is disposed in at least one portion in a range between a position corresponding to 80% and a position corresponding to 100% of the whole length of the shaft from its tip.  
   
   
       2 . A golf club shaft having a fiber reinforced thermosetting resinous material and a fiber reinforced thermoplastic resinous material, 
 wherein said fiber reinforced thermoplastic resinous material has a vibration-damping factor not less than 1.0 has a weight not less than 10% nor more than 60% of a weight of said golf club shaft, and the fiber reinforced thermoplastic resinous material is disposed in the whole length of the shaft.    
   
   
       3 . A golf club shaft having a fiber reinforced thermosetting resinous material and a fiber reinforced thermoplastic resinous material; 
 wherein said fiber reinforced thermoplastic resinous material is disposed only in the grip-mounting portion of the shaft, and said fiber reinforced thermosetting resinous material is disposed only in the head-mounting portion of the shaft; and    said fiber reinforced thermoplastic resinous material has a vibration-damping factor not less than 1.0 has a weight not less than 10% nor more than 60% of a weight of said golf club shaft.    
   
   
       4 . A golf club shaft having a fiber reinforced thermosetting resinous material and a fiber reinforced thermoplastic resinous material; 
 wherein said fiber reinforced thermoplastic resinous material is disposed on the inner peripheral side of the head and the grip of the shaft; and    said fiber reinforced thermoplastic resinous material has a vibration-damping factor not less than 1.0 has a weight not less than 10% nor more than 60% of a weight of said golf club shaft.
