Golf club head

Abstract

A golf club head includes a main body and a plate member disposed on the main body. The plate member includes a plurality of carbon fiber layers which are stacked on each other and are impregnated with a thermoset carbon fiber resin containing carbon nanotubes. The carbon nanotubes are present in an amount ranging from 0.01 wt% to 5 wt%, based on the total weight of the thermoset carbon fiber resin.

What is claimed is: 
     
         1 . A golf club head, comprising:
 a main body; and   a plate member disposed on the main body, said plate member including a plurality of carbon fiber layers which are stacked on each other and are impregnated with a thermoset carbon fiber resin containing carbon nanotubes, said carbon nanotubes being present in an amount ranging from 0.01 wt% to 5 wt %, based on a total weight of said thermoset carbon fiber resin.   
     
     
         2 . The golf club head according to  claim 1 , wherein said plate member has a thickness ranging from 0.4 mm to 0.8 mm. 
     
     
         3 . The golf club head according to  claim 1 , wherein said carbon fiber layers of said plate member are selected from the group consisting of unidirectional carbon fiber fabrics and 3K carbon fiber fabrics. 
     
     
         4 . The golf club head according to  claim 1 , wherein said thermoset carbon fiber resin is an epoxy resin. 
     
     
         5 . The golf club head according to  claim 1 , wherein said plate member is configured to be a crown or a sole of said gold club head.
