Abstract

A carbon fiber bundle includes carbon fibers and a copolymerized polyolefin attached to the surface of the carbon fibers. The copolymerized polyolefin contains an aromatic vinyl compound and an acid and/or acid anhydride as copolymerization components. The amount of the copolymerized polyolefin attached is 0.01 to 10 parts by mass per 100 parts by mass of the carbon fiber bundle. The carbon fiber bundle may be used or contained in a random mat, a composite material, and various molded articles.
