    Abstract: The invention relates to a device for impregnating fiber structures (1) with a matrix material, comprising a lower part (21) with a bath (5) for receiving the matrix material and with a dripping unit, wherein the dripping unit comprises at least one scraper (27) with a scraping edge (29), over which the saturated fiber structure (1) is guided during operation; a surface (25), which is inclined in the direction of the bath and over which the matrix material dripping from the fiber structure (1) can be returned to the bath (5); and a cover (23) on which a deflecting unit (33) is mounted that is used to press the fiber structure (1) into the bath (5) when the cover (23) is mounted. When the cover (23) is mounted, a respective gap (39, 41) is formed between the cover (23) and the lower part (21) on the sides through which the fiber structure (1) is guided into the device and exits the device. The invention also relates to a method in which a fiber structure is impregnated with a matrix material in such a device and subsequently molded into a component.

    Abstract: The invention relates to a method for producing a polyurethane material, wherein (a) di- and/or polyisocyanates, (b) compounds that have hydrogen atoms reactive with isocyanate groups and that do not contain any compounds having carbon-carbon double bonds, (c) compounds containing at least one carbon-carbon double bond, (d) optionally a catalyst that accelerates the urethane reaction and (e) optionally further auxiliary agents and additives are mixed to form a reaction mixture and are cured at temperatures of greater than 120 °C. The compounds having hydrogen atoms reactive with isocyanate (b) have on average at least 1.5 hydrogen groups reactive with isocyanate per molecule, and the compounds having a carbon-carbon double bond (c) contain compounds (c1) that have at least one carbon-carbon double bond and at least one group selected from groups reactive with isocyanate or from isocyanate groups and/or (c2) that have at least two carbon-carbon double bonds. The reaction mixture is stabilized to such an extent that the polyurethane material that is obtained after mixing of components (a) to (c) and, if present, (d) and (e) at room temperature, injection into a metal mold temperature-controlled to 80 °C and having the dimensions 20 cm x 30 cm x 0.4 cm, demolding after 60 minutes and cooling to room temperature, has a heat distortion temperature (three-point bending at 0.45 MPa extreme fiber stress according to DIN EN ISO 75) that is at least 15 °C lower than the heat distortion temperature of the identically produced polyurethane material which, after production, is additionally thermally treated for 120 minutes at 150 °C in a furnace and subsequently cooled to room temperature. The invention further relates to a polyurethane material that can be obtained by a method of this type, and to the use of the polyurethane material, in particular a polyurethane fiber composite material, as structural components.

    Abstract: The invention relates to a method for producing a polyurethane fiber composite material, wherein (a) di- and/or polyisocyanate, (b) compounds with hydrogen atoms which are reactive towards isocyanate groups, (c) compounds containing at least one carbon-carbon double bond, (d) optionally a catalyst which accelerates the urethane reaction, (e) optionally radical starters, and (f) optionally additional auxiliary agents and additives are mixed in order to form a reaction mixture with which a fiber material is wetted and cured. The compounds with hydrogen atoms which are reactive towards isocyanate on average have at least 1.5 hydrogen groups which are reactive towards isocyanate per molecule; the double bond density of the compound (c) is at least 21 pcnt ; the double bond functionality of the compound (c) is greater than 1; the compound (c) does not have groups which are reactive towards isocyanate; and the equivalent ratio of isocyanate groups of the di- and/or polyisocyanates (a) and the hydrogen atoms which are reactive towards isocyanate of the compound (b) is 0.8 to 2. The invention additionally relates to a polyurethane fiber composite material which can be obtained using the method according to the invention and to the use of the polyurethane fiber composite material as structural components.
