The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.

Polyurethane-polyisocyanurate compounds and processes for preparing polyurethane-polyisocyanurate compounds are disclosed herein. A process includes mixing component (a) polyisocyanate with component (b) a mixture obtainable by introducing an alkali metal or alkaline earth metal salt into a compound R&#x2014;NH&#x2014;CO&#x2014;R containing urethane groups, where R is not hydrogen and is not COR, component (c) compounds containing one or more epoxide groups, component (d) one or more compounds having at least two isocyanate-reactive groups, comprising compounds having NH2 and/or primary OH groups, and component (e) optionally fillers and other additives, to form a reaction mixture, and reacting the reaction mixture to form the polyurethane-polyisocyanurate compound, wherein the molar amount of alkali metal and/or alkaline earth metal ions in the reaction mixture per mole of urethane group in component (b) is 0.0001 to 3.5 and the isocyanate index is greater than 150. Use of polyurethane-polyisocyanate compounds for producing vehicle parts is also disclosed.
