Abstract: The invention relates to a method for producing decorative parts with a rear plastic carrier element, which is poured over with plastic under process pressure in a casting tool for producing an upper layer on a front visible side, characterized in that the carrier element is fixed in the casting tool and is impinged upon with pressure at least during the production of the upper layer at the rear and in the direction of the upper layer that is to be produced on the front visible side, said pressure counteracting the process pressure during the overmolding with plastic.
Abstract: The invention relates to a method for producing a trim element for vehicles which has a genuine carbon appearance, comprising a carbon fiber layer which is arranged on an exposed side of the trim element and is visible from the outside, and which is made of a fiber structure composed of prefabricated carbon fibers with interstices, with the method comprising at least the process step of wet impregnating the prefabricated carbon fiber layer with an aqueous polymer dispersion based on polyurethane, acrylate or polyvinyl acetate or a mixture thereof, so that the polymer dispersion penetrates at least partially into the carbon fiber layer, increasing the suitability thereof for penetration of a coating into the interstices of the fiber structure of the carbon layer.

Abstract: The invention relates to a method for producing a natural fiber-reinforced plastic part, wherein as the starting material natural fibers 5-120 mm in length, a thermoplastic and/or a duroplastic and a lubricant, especially wax, are pelletized without extrusion into long-fiber pellets by cold-forming and the long-fiber pellets are then feed for direct processing into a standard injection molding machine for injecting the plastic part.
