Patent number: 11034102Abstract: A process arrangement and a process for the production of a fiber-reinforced plastics component made of at least one continuous-fiber-reinforced semifinished textile fiber product with reactive thermoplastic matrix material, where during the manufacture of the semifinished fiber product trimming residues (mR, mA) arise, composed of a composite made of fibers and of the reactive thermoplastic matrix material, and during finishing of the finished plastics component final-trimming residues (mE) arise, composed of a composite of fibers and of polymerized thermoplastic matrix material, and are further processed in a recycling unit to give a recyclate. The trimming residues arising during the manufacture of the semifinished fiber product are polymerized in a preparatory unit and then are delivered in the invention to the recycling unit.Type: GrantFiled: February 15, 2016Date of Patent: June 15, 2021Assignee: Volkswagen AktiengesellschaftInventors: Thomas Mertens, Max Ehleben, Christine Kunze, Olaf Täger, Maurice Bitterlich, Katja Zeuner, Philippe Desbois, Andreas Wollny

Patent number: 10695991Abstract: A process arrangement for producing a fiber-reinforced plastic component comprises a stacking station in which pre-impregnated textile semi-finished products can be stacked, and an assembly station in which the semi-finished products can be further processed to form the layered packet. The forming of the fiber-reinforced plastic component is subsequently carried out in the press. According to the invention, the stacking station is assigned at least one transport and/or storage container in which the semi-finished products can be stored air-tight, light-proof, and/or moisture-tight shielding and can be transported to the assembly station.Type: GrantFiled: September 23, 2015Date of Patent: June 30, 2020Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: Maurice Bitterlich, Max Ehleben, Katja Zeuner, Thomas Mertens

Publication number: 20200171762Abstract: A method for producing a fiber-reinforced plastic component includes providing an at least two or more-layered textile structure made of a carrier layer onto which a short-fiber layer, in which short fibers are saturated with a not yet polymerized starting component of a reactive thermoplastic matrix material, is applied, making up or producing the textile structure into a fiber-reinforced textile semi-finished fiber product, and pressing/deep drawing the fiber-reinforced textile semi-finished fiber product into a mold for the fiber-reinforced plastic component to be produced, while at the same time heating the fiber-reinforced textile semi-finished fiber product to a temperature above the polymerization starting temperature. A process arrangement for producing a fiber-reinforced plastic component and a fiber-reinforced plastic component are also provided.Type: ApplicationFiled: August 4, 2017Publication date: June 4, 2020Inventors: ALINE KUBISCH, MAX EHLEBEN, THOMAS MERTENS, FABIAN FISCHER, MAURICE BITTERLICH, PHILIPPE DESBOIS

Patent number: 10661482Abstract: A process for the production of fiber-reinforced components or semifinished products is provided, where fibers are saturated with monomer. The process includes at least one of adding flakes including fibers and adding individual fibers. For this, the fibers, the monomer, and the flakes including fibers and/or the individual fibers are added to an injection-molding machine and forced into an injection mold, whereupon polymerization of the monomer is completed in the injection mold. Alternatively a fiber structure on a conveyor belt is saturated with a solution including a monomer, optionally including an activator, and optionally including a catalyst. In a following step, individual fibers and/or flakes including fibers are distributed on the saturated fiber structure, the fiber structure is passed through a roll pair in which pressure is exerted onto the fiber structure, and finally the saturated fiber structure is cooled so that the monomer solidifies.Type: GrantFiled: February 23, 2016Date of Patent: May 26, 2020Assignee: VOLKSWAGEN AGInventors: Philippe Desbois, Andreas Wollny, Max Ehleben, Maurice Bitterlich, Katja Zeuner, Thomas Mertens, Olaf Taeger-Ing

Patent number: 10611889Abstract: The invention relates to a process for the production of saturated fiber structures. The process includes (a) introduction of a fiber structure onto a conveyor belt; (b) application of a solution including monomer and optionally including activator, and optionally including catalyst in at least one line to the fiber structure; (c) passage of the fiber structure with the solution through at least one roll pair in which pressure is exerted on the fiber structure; and (d) cooling of the saturated fiber structure, so that the monomer solidifies.Type: GrantFiled: July 29, 2015Date of Patent: April 7, 2020Assignee: BASF SEInventors: Philippe Desbois, Andreas Wollny, Max Ehleben, Maurice Bitterlich, Katja Zeuner
