  • 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: 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.

  • Patent number: 10538624
    Abstract: A process for producing an activated monomer composition comprising at least one lactam and/or lactone, one catalyst, and one activator permits storage of the resultant monomer composition, since this is stable with respect to polymerization. Said monomer composition is used inter alia in producing a polyamide molding via ring-opening, anionic polymerization.
