An apparatus for the manufacture of fiber-reinforced plastic compositions. The apparatus addresses the disadvantages of previous methods and apparatuses for the manufacture of fiber-reinforced plastic compositions using a plasticizing extruder. Some embodiments of the apparatus may increase and/or better define the fiber content in the plasticate, as well as improve performance in the production of plasticates from fiber fleeces and fiber mats. Embodiments include an apparatus with a plasticizing extruder with adapted geometry of the extruder casing and the corresponding screw elements.

Method and apparatus for the manufacture of fiber-reinforced plastic compositions

The invention is addressed to the problem of providing a method whereby a mixing of bulk material containing fibers (fiber material) and plastic granules for the plasticate extrusion of long fiber reinforced thermoplastics (LFT) will be possible during the melting process with high production outputs and with minimized material content in the extruder system and minimized fiber damage, and to the problem of creating an apparatus with an extruder for the practice of the method, which will have an extruder housing of modified geometry as to the feed opening and the corresponding screw elements, so that the disadvantages described above are avoided.
