Beschreibung
Zusammenfassung:	Provided is a prepreg including: a urethane (meth)acrylate (A) that is a reaction product of a polyisocyanate compound (a1) comprising a polymethylene polyphenyl polyisocyanate (a1-1) as an essential component with a hydroxyl group-containing compound (a2) comprising, as an essential component, a compound (a2-1) having a hydroxyl group and a (meth)acryloyl group; a polymerization initiator (B); and carbon fibers (C) . The prepreg is excellent in workability and molding property and can form molded products excellent in various physical properties such as interlayer shear strength and heat resistance. Thus, the prepreg is suitable for use in various molded articles including automotive members.
