Document Type and Number:
WIPO Patent Application WO/2018/139158
Kind Code:
A1
Abstract:
Provided are: a sizing agent for reinforcing fibers, which is capable of providing reinforcing fibers with excellent strand sizing properties, excellent chopped strand sizing properties and excellent adhesiveness to a matrix resin at the same time, said reinforcing fibers being used for the purpose of reinforcing the matrix resin; a reinforcing fiber strand which uses this sizing agent for reinforcing fibers; a reinforcing fiber chopped strand; and a fiber-reinforced composite material. This sizing agent for reinforcing fibers essentially contains an aromatic polyester urethane resin; the aromatic polyester urethane resin is a reaction product of an organic polyisocyanate compound (A) and an active hydrogen group-containing compound (B); and the active hydrogen group-containing compound (B) essentially contains an aromatic polyester polyol (B1), a tertiary amine compound (B2) that has an active hydrogen group, and an active hydrogen group-containing compound (B3) that has a carboxyl group.
