Improvement of the structural behavior of mineral casting components for use in machine tool construction

VFMG

Development of fiber-reinforced and prestressed mineral casting

In the research project "Prestressed, fiber-reinforced mineral casting", the degree of improvement in structural performance of mineral casting components is being investigated by integrating prestressed fiber reinforcements. The main aim of this material combination is to permanently improve the strength of the mineral casting by adding a textile reinforcement structure. As a result, a new field of application could be established for this material: load-bearing and moving machine tool components.

As part of the project, a method is developed for prestressing the textile reinforcements in mineral casting components. This includes the development and implementation of a fundamentally new system of prestressing a, regarding the force admission and transmission, optimized textile structure. Furthermore, the material design also takes into consideration the aspects of permanent bonding between the mineral casting and the textile structures as well as the maintaining of the prestress.

For the textile reinforcement, different geometries will be investigated depending on the loads occurring in the application case machine tools. The project will conclude with full-scale demonstrator-level components whose mechanical parameters will be determined experimentally.
