Multifunctional High-Performance Components Made from Hybrid Porous Materials

TRR 375 investigates hybrid porous (HyPo) materials to make them usable as high-performance components with specific functionalities. The focus of the research lies in combining different metallic materials with deliberately introduced porosity. The precise composition and porosity are to be tailored to the respective application in order to achieve optimal mechanical and thermal properties for the intended use. This includes locally varying densities and/or material compositions. In addition, research is being conducted on the integration of sensor technology to enable self-diagnosis of the components.

As part of subproject C02, the intrinsic properties of the HyPo components are being investigated at AWP. This must be done in a way that avoids inhomogeneities like pores or material gradients, therefore the tests need to be conducted independent of the shape, size, or position inside a component and on small scales. The focus lies primarily on physical and mechanical characteristics determined by the materials and the manufacturing process.

For this purpose, microstructural features, morphology, and mechanical properties—such as nano-hardness as well as tensile, impact, and fatigue behavior—are comprehensively characterized on miniature specimens extracted from HyPo components. The aim is to identify the fundamental interactions between manufacturing process, microstructure, and the resulting mechanical properties. These findings serve as quality control for the manufacturing process, as comparison between simulation and experiments and ultimately help optimizing the produced components.
