Abstract: A fiber-reinforced resin material laminate 1 is provided with the following: a fiber-reinforced resin material 2 in which a fiber bundle group formed of a plurality of fiber bundles is impregnated with a matrix resin composition; and a first carrier sheet 3 and a second carrier sheet 4 which form a pair and sandwich the fiber-reinforced resin material 2 therebetween, with a mark 5 being provided on a surface 4a of the second carrier sheet 4. In a manufacturing method for the fiber-reinforced resin material laminate 1, during an impregnation step, the fiber-reinforced resin material 2 is formed in a state of being sandwiched between the first carrier sheet 3 and the second carrier sheet 4, and thereafter, the mark 5 is provided by marking the surface 4a of the second carrier sheet 4.

Abstract: The purpose of the present invention is to provide a fiber-reinforced resin material having minimal directionality of strength as well as excellent productivity, a method and device for manufacturing a fiber-reinforced resin material whereby a molded article is obtained, and a device for inspecting a fiber bundle group. A method for manufacturing a sheet-shaped fiber-reinforced resin material in which a paste (P1) is impregnated between cut fiber bundles (CF), the method for manufacturing a fiber-reinforced resin material including a coating step applying a coating of a paste (P1) on a first sheet (S11) conveyed in a predetermined direction, a cutting step for cutting a long fiber bundle (CF) using a cutter (113A), a scattering step for dispersing the cut fiber bundles (CF) and scattering the cut fiber bundles (CF) on the paste (P1), and an impregnation step for pressing a fiber bundle group (F1) and the paste (P1) on the first sheet (S11) and impregnating the paste (P1) between the fiber bundles (CF).
