摘要:
A prepreg 10 comprises: a reinforcing fiber layer 3 including reinforcing fibers 1 and a resin composition 2 with which the space between fibers of the reinforcing fibers is impregnated and which contains (A) a benzoxazine resin, (B) an epoxy resin, and (C) a curing agent having 2 or more phenolic hydroxy groups in a molecule; and surface layers 6a and 6b provided on the surfaces of the reinforcing fiber layer 3 and containing (A) a benzoxazine resin, (B) an epoxy resin, (C) a curing agent having 2 or more phenolic hydroxy groups in a molecule, and (D) polyamide resin particles 4 having an average particle size of 5 to 50 μm, wherein the polyamide resin particles 4 include the polyamide 1010 resin particle.
