Abstract: A process is disclosed for producing polyurethane-polyisocyanurate-fiber composite parts, wherein a composition comprising polyisocyanate, a mixture obtainable by introducing an alkali metal salt or alkaline earth metal salt into a compound R—NH—CO—R′ containing urethane groups, with R′ being not hydrogen and/or not COR″, a compound containing one or more epoxide groups, polyetherol having an average functionality of 1.8 to 5.0 and a hydroxyl number of 200 to 500, a chain extender, fibrous reinforcing agents and optionally further additives form a reaction mixture. The reaction mixture is applied to the fibrous reinforcing agent and caused to react to form the polyurethane-polyisocyanurate-fiber composite part. Further disclosed is a polyurethane-polyisocyanurate-fiber composite part producible by such a process, and also the use of a polyurethane-polyisocyanurate-fiber composite part as a bodywork component of vehicles, such as bumpers, fenders or roof parts, or as structural or semistructural components for vehicles or wind turbines.
