Document Type and Number:
Japanese Patent JP3715386
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of the shaft for a ski stock excellent in flexibility or load absorbability and having a surface excellent in smoothness.
SOLUTION: A sheet laminated body 4A is obtained by rolling up a carbon fiber included prepreg sheet 1A, an aramid-fiber included prepreg sheet 2A, and a glass-fiber included prepreg sheet 3A to a mandrel. This sheet laminated body 4A is treated by heating to perfectly harden the half-hardened resins immersed in the respective prepreg sheets, so that a shaft base material in which carbon-fiber reinforced resin layers, aramid-fiber reinforced resin layers, and glass-fiber reinforced resin layers are laminated is obtained, and this shaft base material is subjected to polishing treatment making a part of the glass-fiber reinforcing resin layers as a polishing allowance.
