Abstract A fiber-reinforced composite material superior in mechanical strength, heat resistance and hot water resistance is provided herein. This composite material is composed of a matrix of a cured product of a resin composition containing as essential components an epoxy resin (A) and an imide compound (B) represented by the following general formula (I), ##STR1## wherein X represents --NH 2 group and/or --OH group, Ar represents an aromatic residue, R 1 represents a hydrogen atom or an alkyl group having from 1 to 10 carbon atoms, R 2 represents a hydrogen atom, an alkyl or alkoxy group having from 1 to 20 carbon atoms or a hydroxyl group, and each of m and n cannot be 0 at the same time, and a fiber (C) as a reinforcing material.
A fiber-reinforced composite material comprising a matrix of a cured product of a resin composition containing as essential components an epoxy resin (A) and an imide compound (B) represented by the following general formula (I), ##STR6## wherein X represents --NH 2 group and/or --OH group, Ar represents an aromatic residue, R 1 represents a hydrogen atom or an alkyl group having from 1 to 10 carbon atoms, R 2 represents a hydrogen atom, an alkyl or alkoxy group having from 1 to 20 carbon atoms or a hydroxyl group, and each of m and n represents a number of from 0 to 30, provided that m and n cannot be 0 at the same time, and a fiber (C) as a reinforcing material.
