    摘要： The invention relates to a fiber composite material (42), comprising at least one fiber layer (4, 14, 16) composed of a fiber material, the at least one fiber layer being embedded in a matrix (8, 18) based on a thermoplastic plastic, wherein the composition of the matrix (8, 18) contains: 60 - 95 wt% of aromatic polycarbonate and/or aromatic polyester carbonate; a constituent composed of a cyclic phosphazene, a salt of a phosphinic acid, or an oligomeric phosphate; and further additives. The invention further relates to the use of such a fiber composite material for a component for a rail vehicle, in particular for a rail vehicle for transporting persons. The invention further relates to a method for producing a fiber composite material, wherein a layer structure (36) of layers arranged one over the other is formed from at least one fiber layer (4, 14, 16) composed of a fiber material and plastic layers, which are arranged on both sides of the fiber layer (4, 14, 16) and are composed of at least one plastic film (30), and wherein the layer structure (36) is pressed into a fiber composite material (42) under the influence of pressure and heat, wherein the plastic film (30) has a composition corresponding to the matrix of the aforementioned fiber composite material.

    摘要： A resin comprising a polycarbonate resin and glass fibers having a flat cross section and having excellent weld strength, stiffness and flame retardancy. The resin is a glass-fiber-reinforced polycarbonate resin composition comprising: (A) 100 parts by weight of a resin component (component A) consisting of a polycarbonate-polydiorganosiloxane copolymer resin (component A-1) and an aromatic polycarbonate resin (component A-2); (B) 10 to 300 parts by weight of glass fibers having a flat cross section (component B) which have an average value of the long diameter of the fiber cross section of 10 to 50 µm and an average value of the ratio of the long diameter to the short diameter (long diameter/short diameter) of 1.5 to 8; (C) 5 to 25 parts by weight of an adhesion improving agent (component C); (D) 5 to 45 parts by weight of a phosphorus-based flame retardant (component D); and (E) 0.01 to 3 parts by weight of a fluorine-containing dripping inhibitor (component E), the content of the polydiorganosiloxane derived from the component A-1 in the resin composition being 0.05 to 4.00 wt%.

    摘要： The invention relates to a process for producing polyurethane prepregs which are stable during storage, and to mouldings (composite components) produced therefrom. The prepregs or components are produced by mixing, for example, (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers with uretdione materials. Optionally, photoinitiators can also be added. This mixture or solution is applied by known processes to fibre material, e.g. carbon fibres, glass fibres or polymer fibres, and is polymerized with the aid of radiation or plasma applications. Polymerization, e.g. at room temperature or at up to 80°C, gives thermoplastics or, respectively, thermoplastic prepregs which can subsequently be subjected to forming processes. By using elevated temperature, the hydroxy-functionalized (meth)acrylate constituents can then be crosslinked with the uretdiones already present in the system. It is thus possible to produce dimensionally stable thermosets and, respectively, crosslinked composite components.
