The potential of mineral casting has already been demonstrated in civil engineering and mechanical engineering. However, depending on the material, reinforcement systems must be provided for the absorption of alternating loads, especially if bending and tensile loads are to be transferred. In civil engineering different options of reinforcement are available for this purpose yet in machine tool building, these options can either be not applied at all or only under limited conditions because they cannot withstand the occurring loads sufficiently. Nevertheless, mineral casting offers undeniable benefits such as e.g. the very good damping capacity and the simple and cost-effective production of parts. The aim of this research project is therefore the development of methods for preloading these mineral casting components with the aid of textile reinforcement structures in order to be able to transfer occurring loads. Principally, the question of the optimal preloading mechanism is answered and how such systems can be designed. Furthermore, it is clarified how a durable connection between the textile structures and the mineral casting can be achieved as well as how the preloading is applied and maintained permanently. In the planned project, the possible applications of fibre-reinforced, preloaded mineral casting for various applications in machine tool building will be investigated and, derived from this, possibilities will be developed as to how the material properties of this hybrid composite can be optimally adapted to the loads that occur. On the basis of prototypically implemented structures, the actual properties will be experimentally determined.
