Lightweight high-performance materials are needed in many industrial processes and in particular when energy consumption can be minimized efficiently by weight reduction with the quality of the material remaining constant. Various applications, such as fiber composites for aerospace technology, rotor blades in wind power plants, or the constantly growing use of fiber composite materials in the automotive sector require various material and processing parameters to be integrated in automatic production processes. Scientists at the Institute of Catalysis Research and Technology (IKFT) design reactive resin systems for liquid composite molding processes, in which carbon or glass fiber materials are produced. First, the liquid reactive resin component is hardened in the presence of the fiber component. This results in a composite material of a plastic matrix and fiber component. It is concentrated on materials based on epoxy resins, whose exceptional processing properties are developed specifically. Another main activity is the development of customized resin systems for non-thermal curing technologies, such as electron beam hardening. It is aimed at a (series) production of low-cost and light composite materials with excellent mechanical properties and high thermal and chemical resistance. Such reactive resins are not only used in lightweight construction, but also in adhesives and coatings or, due to low electric conductivity, in many electronic applications. Major parameters, such as tension, bending, shear strength, impact strength or glass transition temperatures, can be adapted for the application. For automatic production processes, optimum processing parameters, such as resin viscosities, hardening temperatures, and cycle times as well as reactivities of the resin formulations are important. By an optimum selection of such parameters, the high quality of the resulting materials is ensured and energy consumption needed for production is reduced significantly.
