SUPERHEATED STEAM-TREATED CARBON FIBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a superheated steam-treated carbon fiber excellent in adhesion with a resin, and a method for producing the same.SOLUTION: The superheated steam-treated carbon fiber is a carbon fiber subjected to a surface treatment in an atmosphere containing superheated steam. The superheated steam-treated carbon fiber can be produced by treating a carbon fiber raw material preferably in an atmosphere of 400-800°C. The superheated steam may be used in combination with at least one selected from nitrogen, carbon dioxide, argon and helium.
