CARBON FIBER BUNDLE AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a carbon fiber bundle to which an amino group-containing modified polyolefin resin has applied, wherein the amount of applying amino group-containing modified polyolefin resin is 0.2 to 5.0% by mass. This carbon fiber bundle can be produced by applying 0.2 to 5.0% by mass of the amino group-containing modified polyolefin resin to the surface of the carbon fiber bundle. The present invention can exhibit excellent interface adhesion to a polyolefin resin, particularly to a polypropylene resin, and can provide a carbon fiber bundle useful for reinforcing the polyolefin resin and a method of producing the same.
