Abstract

The present invention relates to the use of hydrophopic polyols for producing fiber composite components on the basis of a polyurethane/polyisocyanurate reaction mixture, to a method for producing composite components and to the composite components as such. The method according to the invention is particularly economical in terms of saving material and time costs and the composite components obtained are characterized by excellent visual and material properties.
