摘要： The present invention provides a prepreg comprising a reinforcement fiber [A], an epoxy resin [B] having two or more epoxy groups per molecule, a compound [C] capable of curing component [B], crosslinked resin particles [D] having a refractive index in the range of 1.49 to 1.61, and carbon black [E]. Furthermore, the surface layer of the prepreg that occupies 10% of the average prepreg thickness from each surface of the prepreg comprises components [B] to [E], and the refractive index, n0, of a cured epoxy resin produced by curing a resin composition comprising component [B] and component [C] and the refractive index, n1, of component [D] have the following relationship: 0.92≦n1/n0≦1.05. Thus, the invention provides a prepreg that can produce fiber reinforced composite materials having decorative surfaces with decreased appearance irregularities and accordingly serves to manufacture fiber reinforced composite materials having excellent appearance.
