Reinforcing fiber bundle and carbon fiber reinforced thermoplastic resin molded body using the same, and method for producing reinforcing fiber bundle

Abstract

Disclosed are a reinforcing fiber bundle composed of a carbon fiber bundle treated with an emulsion; a carbon fiber reinforced thermoplastic resin molded body using the same; and a method for producing a reinforcing fiber bundle; wherein the emulsion contains a modified polyolefin (A1) comprising at least a metal carboxylate bonded to the polymer chain, and 0.1 to 5,000 moles of an amine compound (B) represented by the following general formula (1), per one mole of the carboxylate group in the modified polyolefin (A1); R—NH2  (1) wherein the formula (1), R is a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms.
