To provide a metal-hybrid prepreg which gives a prepreg product excellent in strength. appearance, and touch in use.
In the metal-hybrid prepreg, a reinforcing fiber prepreg of a 5-30 μm fiber diameter is made a base layer, metal wires or foil 5-100 μm in thickness, 0.1-100 mm in width, and 2-10 in width/thickness ratio of 2-100 are arranged at 0.1-100 mm intervals on the surface side of the base layer, the reinforcing prepreg is laminated as a transparent cover layer on the wires or the foil, and in a metal-hybrid prepreg processing product, the prepreg is wound so that the cover layer is arranged on the surface side. In a method for producing the metal-hybrid prepreg by drum winding, the brake of a winding out bobbin is controlled by the detected tension of the metal wires, and the tension the metal wires is kept constant within a range of 40-400 gf/strand.
