Abstract
A method for producing a material for a fiber-reinforced composite article is disclosed which comprises preparing an apparatus composed of a belt and at least one fiber-separating and throwing device, setting the belt in motion and the roller in rotation, feeding a mixture of matrix thermoplastic resin fibers (a) and reinforcing fibers (b) to the roller, causing the roller to separate the fibers and throw the separated, fibers, and allowing the thrown fibers to pile up on the moving belt, thereby giving rise to a mat wherein the ratio of the fibers (a) and (b) successively increases or decreases in the direction of thickness of the mat.
