    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.
