Abstract

Described herein is a process for preparing a polyurethane-type fiber composite material, said process including (a) di- and/or polyisocyanates, (b) compounds having isocyanate-reactive hydrogen atoms, (c) compounds including at least one carbon-carbon double bond, (d) optionally a catalyst to hasten a urethane reaction, (e) optionally a free-radical initiator, and (f) optionally further auxiliary and added-substance materials, being mixed into a reaction mixture—with concomitant wetting of a fiber material—and cured. Also described herein is a polyurethane-type fiber composite material obtainable by a process described herein and also to a method of using the polyurethane-type fiber composite material as a structural component part.
