    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.

    Abstract: In a process for the production of pore-free polyurethane elastomer moldings with Shore D hardness of at least 60 in accordance with DIN 53505, (a) polyesterdiol with OH number from 20 to 100 mg KOH/g and (b) a chain extender composed of diol with molar mass below 300 g/mol, is mixed with (c) isocyanate prepolymers obtainable via reaction of diisocyanate with polyesterols with functionality from 1.95 to 2.2 and with OH number from 20 to 200 mg KOH/g to form a reaction mixture. The reaction mixture is charged to a mold and hardened to form the polyurethane elastomer. Polyurethane elastomer moldings are thus obtainable by this process, and these polyurethane moldings may be used as cladding component for commercial vehicles, bodywork component in vehicle construction, or a cladding component of a machine installation.
