  • Publication number: 20050227080
    Abstract: Fiber-reinforced structural parts are coated to refine and color the surfaces especially if they are used as body parts in the automotive industry. According to the invention, a plastic film that already has the desired properties regarding the structure and optionally the color of the surface of the structural part and that is already preformed corresponding to the topography of the surface of the structural part is inserted in a corresponding mold. A fiber-reinforced plastic, preferably comprising a duroplastic or thermoplastic matrix, is applied to the side of the preformed film that is not the surface by means of a method adapted to the composition of the semi-finished product and finished structural part is withdrawn from the mold once the fiber-reinforced plastic has been pressed and hardened or cooled off.

  • Patent number: 6221293
    Abstract: A method for producing a compound from a plastics material with fixed fiber inlay uses a heated screw-type extruder (1) in which filaments (2) are drawn by means of automatic drawing-in, are cut up and mixed there and are subsequently removed as a finished fiber compound. To achieve a high content of long fibers in the finished fiber compound, before entering the extruder (1) the filaments (2) are impregnated with the plastics material in an impregnation tool (3).
