SIZING AGENT-STUCK CARBON FIBER BUNDLE, METHOD FOR PRODUCING THE SAME, AND METHOD FOR PRODUCING PRESSURE VESSEL USING THE SIZING AGENT-STUCK CARBON FIBER BUNDLE

摘要

PROBLEM TO BE SOLVED: To provide a sizing agent-stuck carbon fiber bundle having high resin impregnation properties, also having scratch resistance and thread breakage resistance and particularly suitable for a filament wind molding method, and a method for producing the same.;SOLUTION: A carbon fiber bundle is immersed into a sizing bath so as to be stuck with a sufficient amount of sizing agent, and thereafter, a gas is sprayed on the carbon fiber bundle to remove a part of the sizing agent stuck to the external layer part of the carbon fiber bundle, thus the sizing agent-stuck carbon fiber bundle having high scratch resistance, thread breakage resistance and resin impregnation properties can be obtained.;COPYRIGHT: (C)2014,JPO&INPIT
