A fiber composite material obtainable by (a) mixing the components of a multicomponent composition immediately before use, component A of the multicomponent composition comprising at least one compound having two or more isocyanate groups, component B of the multicomponent composition comprising 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 of epoxy groups, and at least one of the components of the multicomponent composition comprising at least one epoxide prepolymer, (b) introducing the resulting use preparation into a mold in which fibers and optionally further additives are present, the resulting mixture comprising at least one latent hardener for epoxide prepolymers, (c); pre-hardening the resulting mixture at a temperature of 5 DEG C to 90 DEG C and (d) finally, conclusively hardening the prehardened fiber composite material at temperatures of 100 DEG C to 240 DEG C, the
