Artificial feather for shuttlecock, shuttlecock, and method of manufacturing artificial feather for shuttlecock

Abstract

An artificial feather for a shuttlecock including: a sheet form vane portion; and a rachis portion supporting the vane portion, the rachis portion being made of resin including glass fiber and carbon nanotube.

1 . An artificial feather for a shuttlecock comprising:
 a sheet form vane portion; and a rachis portion supporting the vane portion, the rachis portion being made of resin including glass fiber and carbon nanotube.   
     
     
         2 . The artificial feather for a shuttlecock according to  claim 1 , wherein
 the rachis portion is put in between at least two sheet form members including the vane portion.   
     
     
         3 . The artificial feather for a shuttlecock according to  claim 1 , wherein
 the carbon nanotube includes a functional group.   
     
     
         4 . The artificial feather for a shuttlecock according to  claim 3 , wherein
 the carbon nanotube includes at least one of a carboxyl group and a hydroxyl group as the functional group.   
     
     
         5 . The artificial feather for a shuttlecock according to  claim 1 , wherein
 the content of the carbon nanotube in the resin including the glass fiber and the carbon nanotube is equal to or less than 0.4 weight %.   
     
     
         6 . A shuttlecock comprising: a base portion; and a plurality of artificial feathers arranged circularly to the base portion, wherein
 the artificial feather includes a sheet form vane section and a rachis portion supporting the vane portion,   the rachis portion being formed with resin including glass fiber and carbon nanotube.   
     
     
         7 . A manufacturing method of an artificial feather for a shuttlecock comprising a sheet from vane portion and a rachis portion supporting the vane portion,
 the rachis portion being formed with resin including glass fiber and carbon nanotube.   
     
     
         8 . The method of manufacturing an artificial feather for a shuttlecock according to  claim 7 , comprising:
 preparing a first masterbatch combined with the glass fiber;   preparing a second masterbatch combined with the carbon nanotube; and   forming resin including the glass fiber and the carbon nanotube by mixing the first masterbatch, the second masterbatch, and resin not including the glass fiber and the carbon nanotube.
