(57) [Summary] [Purpose] As a matrix resin for SMC, it is excellent in impact resistance, fatigue resistance, and heat resistance, and can be easily B-staged. Provided is an epoxy resin composition which is excellent in workability and compression moldability and has a high curing rate. [Composition] Epoxy resin; 100 parts by weight, having a radical-polymerizable functional group, and the average number of hydroxyl groups exceeds 1 and is 2.5. Less than 10 to 100 parts by weight of a polyisocyanate compound; the epoxy resin, an amount of 0.3 to 2 equivalents relative to 1 equivalent of the total hydroxyl groups in the alcohol compound, and a latent curing agent for the epoxy resin; 1-20 An epoxy resin composition comprising 1 part by weight. |
