More Information
Summary:An object of the present invention is to provide: a prepreg having an excellent tackiness as well as an excellent resin strength after curing and strength in the non-fiber direction; and a fiber-reinforced composite material using the prepreg. The present invention provides a prepreg composed of reinforcing fibers and a resin composition,wherein the resin composition includes the following components [A] to [C]:[A]: an epoxy resin;[B]: a dicyandiamide; and[C]: a compound which has a melting point of 130°C or lower and a solubility parameter whose difference from the solubility parameter of [B] is 8 or less; andwherein the resin composition has a viscosity at 25°C of 1,000 Pa·s or more.
