Abstract
A resin composition for fiber reinforced plastic which is a resin composition comprising an epoxy resin (A), a cyanate resin (B) and a liquid aromatic amine curing agent (C), and, as necessary, further an active energy radiation absorbable component (D), wherein 20 to 100 percent by mass of the aforementioned epoxy resin (A) is an epoxy compound expressed by the following general formula (1), a cured product obtained by curing a composition containing said resin composition and a high-strength fiber-reinforced plastic; wherein (a) and (b) each independently express an integer from 2 to 10, (c) expresses an integer from 0 to 3, R1 and R2 each independently express a bivalent hydrocarbon group having 2 to 5 carbon atoms, and R3 expresses a single bond, a methylene group or —C(CH3)2—.
