| description | PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material with high strength.SOLUTION: The fiber-reinforced composite material is a fiber-reinforced plastic which is composed of: a fiber bundle of reinforcing fibers in which monofilament fineness of the reinforcing fibers is 1.0 to 2.4 dtex and the cross-sectional shape orthogonal to the fiber axis, of a monofilament has a roundness of 0.7 to 0.9; and a cured substance of epoxy resin composition including epoxy resin and an epoxy resin curing agent. The roundness is a value obtained by the following equation (1), and S and L are respectively the cross-sectional area and the peripheral length of the monofilament obtained through observation of the cross-sectional shape orthogonal to the fiber axis, of the monofilament of the reinforcing fibers by using an optical microscope and image analysis. Roundness=(4 S)/L...(1)
