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 mixturewith concomitant wetting of a fiber materialand 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.

A process for making polyurethane includes dissolving a metal acetyl acetonate catalyst in a solvent to form a catalyst solution including greater than 0.25 to 42 weight percent, or 4.8 to 42 weight percent, of metal acetyl acetonate catalyst, based on a total weight of the catalyst solution; combining the catalyst solution, a polyol, and an isocyanate to form a reactive mixture; and curing the reactive mixture to form polyurethane.
