Description
technical field [0001] The invention relates to novel mixtures comprising cyanamide and at least one urea derivative, liquid curing agents for curing epoxy resins, and epoxy resin compositions comprising liquid curing agents for the production of fiber composites. Background technique [0002] Thermosetting epoxy resins are widely used due to their good chemical resistance, very good thermal and dynamic-mechanical properties and high electrical insulating capacity. Furthermore, epoxy resins show good adhesion to many substrates and are therefore most suitable for use in fiber composites (composites). For use in fiber composites, both good wetting of the fibers, ie, low viscosity of the resin formulation selected for the production of the composite, and high mechanical properties after complete curing are desired. [0003] Molded parts are produced from fiber composite materials using various methods, such as pre-impregnation methods, various infusion methods or injection me...
