    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.
