A process for the preparation of fiber-reinforced plastic molding includes (1) shortening the fibers to a length of less than 30 mm; (2) introducing the fibers and the plastics present in the solid state, separately from one another, into a mixing chamber of a die press, wherein the plastic is in particulate form; (3) thoroughly mixing the plastic and fibers to give a solids mixture; (4) transporting the solids mixture through die orifices of the die press; (5) heating the solids mixture in the zone before or in the orifices of the die; (6) enclosing at least part or partly embedding the fibers by the plastic during or after the heating of the solids mixture; and (7) comminuting the granulated material for subsequent molding.

1. A process for the preparation of a plastic material for molding, comprising:shortening a plurality of fibers to a length of less than 30 mm; introducing the fibers and a plastic in particulate form, separately from one another, into a mixing chamber of a die press; thoroughly mixing the plastic and the fibers to form a solids mixture; transporting the solids mixture through a die of the die press having die orifices; heating the solids mixture before or during the transporting through the die orifices, wherein the plastic of the solids mixture is at least partly plastified and/or at least partly softened by the heating; enclosing or embedding at least part of the fibers in the plastic during or after the heating and before emerging from the die orifices; and comminuting or granulating the material from the die to form the plastic material for molding.
