PURPOSE:To enable molding of a uniform pipe material without generating creases and does not cause lowering of compression strength, shock strength and rupture in torsion strength even if it is a material obtained by forming a stepped part on, for example, the pipe material. CONSTITUTION:A foil-like expanded metallic layer 3 is laminated on one side of a fiber-reinforced composite resin layer 4 impregnated with matrix resin 5 within a reinforced fiber 2, in a fiber-reinforced prepreg 1. |
