Patent ID: 10899896

Abstract:
Disclosed are: a reinforcing fiber bundle with excellent mechanical property and handling property, which contains a propylene-based resin (A), a propylene-based resin (B) comprising at least a carboxylic acid salt bonded to the polymer chain, and a reinforcing fiber (C) wherein the propylene-based resin (A) comprises more than 70% by mass but not more than 100% by mass of a component (A-1) having a weight average molecular weight of 150,000 or more, the amount of the propylene-based resin (B) is 3 to 50 parts by mass per 100 parts by mass of the propylene-based resin (A), and the total content rate of the propylene-based resin (A) and the propylene-based resin (B) is 0.3 to 5% by mass in the whole reinforcing fiber bundle; and a molding material comprising the reinforcing fiber bundle and a matrix resin.
