Zusammenfassung:A process for preparing glass fiber reinforced plastics using high-energy radiation. A sizing composition is applied to the glass fiber, and the curing mechanism of the sizing composition proceeds in a controlled way by the use of two crosslinking mechanisms which can be activated separately from one another. Aqueous UV-curing polyurethane dispersions containing few or no active hydrogen atoms are used in combination with water-dispersible or water-soluble blocked polyisocyanates.
