Title: FIBER-REINFORCED COMPOSITE MATERIAL
Abstract:
Provided is a fiber-reinforced composite material capable of simultaneously achieving CAI, ILSS, and interlayer fracture toughness at high levels, and, in particular, of achieving high CAI. Said composite material is characterized by: comprising a laminate including a plurality of reinforcing fiber-containing layers; having a resin layer in each interlayer region for each reinforcing fiber-containing layer; the resin layers being layers wherein at least a polyamide 12 powder is impregnated into a cured product of an epoxy resin and a compound having a benzoxazine ring indicated in formula (1) in the molecules thereof; and the ratio between the thicknesses of each resin layer and the each reinforcing fiber-containing layer being 1:2-6. [Formula 1] (R1:C1-C12 chain alkyl group, etc. H is bonded to the C at at least either the O-position or the P-position of the carbon atom to which an oxygen atom is bonded, in an aromatic ring in formula.)
