Abstract

The invention relates to storage-stable prepregs (preimpregnated fibers) based on low-viscosity polyurethane systems having a very high characteristic number and flat fiber composite components (molded bodies; composite components) produced therefrom, which are obtained due to an impregnation method of fiber reinforced materials such as woven fabrics and fleece, and to a method for the production thereof.
