Abstract

The invention relates to a storage-stable resin film based on polyurethane systems having a very high characteristic number and fiber-composite components (composite components, molded bodies) produced therefrom by compressing the resin film, in combination with fiber-reinforced materials such as woven fabrics and fleece, at high temperatures and under pressure, and to a method for the production thereof.
