To provide a resin composition for a prepreg, which is a prepreg comprising a urethane (meth)acrylate (A), a polymerization initiator (B) and a thermoplastic resin (C) as essential components A body resin composition, wherein the urethane (meth)acrylate (A) is a reaction product of a polyisocyanate (a1), a polyol (a2) and a hydroxyalkyl (meth)acrylate (a3), The above-mentioned polyisocyanate (a1) is a carbodiimide modification selected from the group consisting of 2,4'-diphenylmethane diisocyanate, 4,4'-diphenylmethane diisocyanate and 4,4'-diphenylmethane diisocyanate. Properties, and one or more kinds of polyisocyanates among polymethylene polyphenyl polyisocyanates. The resin composition for prepregs of the present invention is excellent in moldability and can obtain molded articles excellent in various physical properties such as flexibility, impact resistance, and heat resistance, and thus can be suitably used for prepregs and molded articles thereof. |
