SURFACE-TREATED CARBON FIBER, METHOD FOR PRODUCING THE SAME AND CARBON FIBER-REINFORCED RESIN COMPOSITE

摘要

To provide a carbon fiber that can be used for a carbon fiber-reinforced resin composite using an unsaturated polyester resin or vinyl ester resin as a matrix having insufficient adhesion to carbon fiber, and a method that makes it possible to produce the same conveniently.SOLUTION: A method for producing surface-treated carbon fiber has Step 1 in which carbon fiber is brought into contact with aqueous solution containing Snand then with aqueous solution containing Pd, or, carbon fiber is brought into contact with colloid solution containing Snand Pdto attach tin and palladium to the carbon fiber surface, and Step 2 in which the tin and palladium attached to the carbon fiber surface is coupled to a silane coupling agent.SELECTED DRAWING: None
