More Information
Summary:Provided is a prepreg resin composition, containing: a urethane (meth)acrylate (A) that is a reaction product of polyisocyanate (a1), polyol (a2), and hydroxy alkyl (meth)acrylate (a3); a polymerization initiator (B); and a thermoplastic resin (C), as an essential component, in which the polyisocyanate (a1) is at least one polyisocyanate selected from 2,4′-diphenyl methane diisocyanate, 4,4′-diphenyl methane diisocyanate, a carbodiimide modified product of 4,4′-diphenyl methane diisocyanate, and polymethylene polyphenyl polyisocyanate. The prepreg resin composition of the invention is excellent in molding properties, and is capable of forming a molded article excellent in various physical properties such as flexibility, impact resistance, and heat resistance, and thus, can be preferably used in a prepreg and a molded article thereof.
