  • Patent number: 10695991
    Abstract: 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.

  • Publication number: 20200171762
    Abstract: 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.

  • Patent number: 10661482
    Abstract: 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.

  • Patent number: 10611889
    Abstract: 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.

  • Patent number: 10543648
    Abstract: 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 arise, composed of a composite made of fibers and of the reactive thermoplastic matrix material. The trimming residues obtained during the manufacture of the semifinished fiber product are supplied to a recycling unit for the provision of a recyclate as reactive, as yet unpolymerized starting material for the production of a further component.

  • Publication number: 20180250924
    Abstract: In order to optimize a method for stiffening a metal component by pressing a fiber-reinforced plastic insert onto the metal component in such a way that the method can be integrated into the serial production of the car body, it is proposed that the fiber-reinforced plastic insert be picked up by means of a robot-controlled application head and pressed onto the metal component.

  • Publication number: 20180065326
    Abstract: 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.
