Beschreibung
Zusammenfassung:	Provided is a prepreg which can be cured in a short time even at a low temperature, and capable of obtaining a fiber-reinforced composite resin shaped article having an excellent mechanical property including bending elastic modulus, bending strength, breaking strain, and the like and an excellent heat resistance. The prepreg of the present invention comprises an epoxy resin composition and reinforced fiber, the epoxy resin composition comprising component (A): an oxazolidone type-epoxy resin, component (B) a novolac type-epoxy resin, component (C): an urea compound, and component (D): a curing agent, wherein the content of the component (A) is 40wt% to 70wt% and the content of the component (B) is 15wt% to 40wt% with respect to the total mass of all of epoxy resin contained in the epoxy resin composition.
