Claim 0:
1. A fiber-reinforced composite material, comprising:
a cured product of a two-liquid curable composition,
wherein the cured product comprises:
the two-liquid curable composition, and
a reinforcing fiber;
wherein the two-liquid curable composition comprises:
an active hydrogen component comprising an alkylthio group-containing aromatic diamine; and
a diisocyanate component comprising at least one diisocyanate selected from the group consisting of an aliphatic diisocyanate, an alicyclic diisocyanate, a modified aliphatic diisocyanate, and a modified alicyclic diisocyanate;
wherein an isocyanate group content of the diisocyanate compound is from 15% to 50% by mass,
a content of the at least one diisocyanate is at least 80% by mass based on a total content of the diisocyanate component; and
a content of the alkylthio group-containing aromatic diamine is a least 40% by mass based on a total content of the active hydrogen component.
