METAL/FIBER-REINFORCED RESIN MATERIAL COMPOSITE BODY AND METHOD FOR PRODUCING SAME
FIG6 is an illustrative diagram showing a configuration of a sample of a metal-FRP composite body for a shear test in examples and comparative examples 
As shown in FIG6, two metal members 110 were prepared, respective parts of 10 mm from ends of the metal member 110 were bonded to a CFRP layer 120 formed to have a total thickness of 0.2 mm or 0.4 mm, and thereby samples of a metal-CFRP composite body for a shear test were produced. That is, the samples of a metal-CFRP composite body for a shear test were produced by inserting a CFRP layer 120 between vicinities of ends of two upper and lower metal members 101 and performing thermocompression bonding under conditions shown in examples and comparative examples. Two white arrows in FIG6 indicate a tensile load application direction.

['1. A method for producing a metal/fiber-reinforced resin material composite body including a metal member and a fiber-reinforced resin material which is laminated on at least one surface of the metal member and includes a reinforcing fiber substrate and a resin including a thermoplastic resin impregnated into the reinforcing fiber substrate as a matrix resin, the method comprising following a step A and a step B: the step A: forming a prepreg in which a partially fused structure of the resin including the thermoplastic resin is formed on at least one surface of the reinforcing fiber substrate; and the step B: performing a heat and pressure treatment when a surface on which the partially fused structure of the prepreg is formed is brought into contact with a surface of the metal member; and at the same time in which the resin including the thermoplastic resin is completely melted and wet and spreads on the surface of the metal member and the resin including the thermoplastic resin is impregnated into the reinforcing fiber substrate, thereby forming a metal/fiber-reinforced resin material composite body, wherein the fiber-reinforced resin material and the metal member are bonded to form the metal/fiber-reinforced resin material composite body.', '8. The method for producing a metal/fiber-reinforced resin material composite body according to claim 1, wherein, in the step B, a resin layer having a thickness of 20 µm or less and a fiber content of 5 weight% or less is formed using the resin including the thermoplastic resin between the surface of the metal member and the reinforcing fiber substrate as a part of the fiber-reinforced resin material.']
