  • 1C system, products to be manufactured from the system, and a method for manufacturing semifinished, fiber-reinforced products and components with the 1C system
    Patent number: 10040917
    Abstract: The invention relates to a 1C system and a method for manufacturing semifinished products (prepregs) and components with the 1C system. The problem is solved by a 1C system comprised of an epoxy resin and a secondary amine; the secondary amine is imidazole, an imidazole derivative or a complex of the general formula MeL4X2, wherein Me is a bivalent metal cation selected from copper, cobalt, nickel and zinc, L is a ligand selected from imidazole and an imidazole derivative, and X is an anion selected from fluoride, chloride, bromide, iodide and nitrate. Furthermore, the invention includes a method for manufacturing impregnated semifinished products for the production of duroplastic fiber-reinforced components using a 1C system.
