, and the latter half to a thickness of 2 mm, and on top of that, a prepreg using carbon fiber fabric as the fiber structure material and epoxy resin as the matrix resin was wrapped in both the first half and the second half.
After wrapping to a thickness of 0.5 mm, tape wrapping was performed, and the epoxy resin was heat-cured at 135° C. for 90 minutes. After heat curing, the mandrel was removed from the cured product, the wrapping tape was removed, centerless polishing was performed to smooth the surface, and a clear coating was applied. In this case, it is necessary to finish the surface of the tubular body with paint especially for the front half in order to improve the sliding of the fingers.
