Abstract

A fiber composite material obtainable by (a) mixing the components of a multi-component agent immediately before use, wherein component A of the multi-component agent contains at least one compound having two or more isocyanate groups, component B of the multi-component agent contains at least one compound which has at least two reactive groups selected from hydroxyl groups, thiol groups, primary amino groups and secondary amino groups and is simultaneously free from epoxy groups, and at least one of the components of the multi-component agent contains at least one epoxide prepolymer, (b) introducing the resulting application preparation into a mold in which fibers and optionally further additives are present, the resulting mixture containing at least one latent hardener for epoxide prepolymers, (c) pre-curing the resulting mixture at a temperature from 5° C. to 90° C., and (d) then finally curing the pre-cured fiber composite material at temperatures from 100° C. to 240° C., wherein the fiber composite material being removed from the mold after step (c) or step (d).
