The subject of the present invention is to provide prepregs and laminates for manufacturing laminates that are ideal as structural materials. The laminate system has excellent flame resistance, compressive strength, and interlaminar fracture toughness values, and can be used for other structural members. Welded and firmly integrated. The present invention is a prepreg that contains the constituent elements [A] reinforcing fiber, [B] thermosetting resin, and [C] thermoplastic resin. It is characterized in that: [B] contains average cyanic acid Cyanate ester resins with an ester equivalent of 220 or less, bismaleimide resins with an average maleimide equivalent of 210 or less, and average Benzo with equivalent weight less than 300 At least one type of resin, [C] exists on the surface of the prepreg, and is included in the interface between the resin domain containing [B] and the resin domain containing [C] and is included in the two resin domains [A] The presence of reinforcing fibers. |
