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 (P) 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 (P) on a first sheet (S) conveyed in a predetermined direction, a cutting step for cutting a long fiber bundle (CF) using a cutter (A), a scattering step for dispersing the cut fiber bundles (CF) and scattering the cut fiber bundles (CF) on the paste (P), and an impregnation step for pressing a fiber bundle group (F) and the paste (P) on the first sheet (S) and impregnating the paste (P) between the fiber bundles (CF).
