Abstract
A method of manufacturing a sheet molding compound, comprises (i) allowing short fiber bundles to fall onto a travelling carrier film, while dispersing the short fiber bundles using a dispersion roller device, thereby depositing a fiber mat on the carrier film, and (ii) impregnating the fiber mat with a thermosetting resin composition, wherein the dispersion roller device has a rotationally driven dispersion roll, bearings, a first side cover, and a second side cover, wherein the dispersion roll comprises a roll body and roll body-adjoining parts, and an inner circumferential surface of a circular opening provided in each of the first and second side covers and a cylindrical circumferential surface of each of the roll body-adjoining parts face each other.
