A resin composition that has good heat resistance and handleability and that can produce a prepreg which has a good balance between tackyness and drapability and which causes little resin flow during prepreg molding, a prepreg that is manufactured using the resin composition, and a fiber-reinforced composite are provided. A resin composition that contains a maleimide compound, diallyl bisphenol A, and a diallyl isophthalate polymer, a prepreg in which reinforcing fibers are impregnated with the resin composition, and a fiber-reinforced composite material that is obtained by molding the prepreg are provided.

Resin composition, prepreg using the same, and fiber-reinforced composite material

Provided is a method for producing a good epoxy resin composition for obtaining fiber-reinforced plastics. A production method for obtaining a fiber-reinforced composite material by impregnating a fiber assembly with an epoxy resin composition and then curing the epoxy resin composition, wherein the epoxy resin composition contains a component [A], a component [B] and a component [C] respectively satisfying the conditions described below. When the blending amount of the component [B] is set to b parts by mass and the blending amount of the component [C] is set to c parts by mass relative to 100 parts by mass of the component [A] contained in the epoxy resin composition, formula (2) is satisfied within the range of formula (1), formula (4) is satisfied within the range of formula (3), and formula (6) is satisfied within the range of formula (5).
