CARBON FIBER BUNDLE AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a carbon fiber bundle in which an amino group-containing modified polyolefin resin adheres to a carbon fiber bundle and the amount of the amino group-containing modified polyolefin resin adhering to the carbon fiber bundle is 0.2-5.0% by mass. The carbon fiber bundle is able to be produced by having 0.2-5.0% by mass of an amino group-containing modified polyolefin resin adhere to the surface of a carbon fiber bundle. The carbon fiber bundle exhibits excellent interfacial adhesion to polyolefin resins, especially to polypropylene resins, and is useful for the reinforcement of polyolefin resins. Also disclosed is a method for producing the carbon fiber bundle.
