Provided is a storage-stable polyurethane prepegs and mouldings produced therefrom composed of polyurethane compositions with liquid resin components, preferably liquid polyols. A prepeg contains(A)a fibrous support and (B)a matrix material containing a reactive polyurethane composition. The polyurethane composition contains a mixture of a liquid resin component(b)having a functional group reactive towards an isocyanate and having a glass transition temperature(Tg)or melting point below 25&#xb0; C., with a hydroxyl number of 50 to 2000 mg KOH/gram, and a curing agent(a)comprising a di- or polyisocyanate internally blocked or blocked with a blocking agent. In addition, the polyurethane composition contains 0.6 to NCO equivalents or 0.3 to 1 uretdione group in (a) for each functional group of (b).
