Abstract

A method of producing a fiber composite component part, contains the following steps: a) providing two or more steel sheets; b) providing at least one textile fabric; c) providing an anhydrous mixture having one or more than one hardener containing a uretdione having an NCO functionality of not less than two, one or more than one binder having hydroxyl groups to an OH functionality of three to six, and one or more than one cobinder having oxirane groups; d) coating the textile fabric with the mixture; e) applying energy to the mixture-coated fabric for the purpose of performing a first crosslinking reaction to react hardener, binder and cobinder to form a thermoplastic polymer adhering to the textile fabric; f) hot pressing the steel sheets and the textile fabric together with the thermoplastic polymer adhering thereto into a sandwich such that the thermoplastic polymer joins the steel sheets together while enclosing the textile fabric; g) forming the sandwich into a shaped article; h) heat treating the shaped article to obtain the fiber composite component part, wherein the thermoplastic polymer undergoes a second crosslinking reaction to convert into a thermoset polymer.
