Hybrid material systems are created by the purposeful combination of different materials. This allows to achieve property profiles that would not be possible with mono-material solutions. For lightweighting, high-strength and highly rigid complex-shaped structural components used in the automotive and aerospace industries, hybrid material systems offer outstanding potential in terms of mechanical and dynamic properties.
An in-depth fundamental understanding regarding the interaction of the individual components of the hybrid material system is of great importance for a more efficient design of future structures. This is the starting point for the projects Hybrid Material Systems and HyCEML, which are aimed at closing this scientific gap and increasing the understanding of hybrid material systems and their mechanisms of action.
The aim is to systematically work through and evaluate the mechanism of action that lead to changes in the property profiles, taking into account the boundery conditions, and to describe those with aid of suitable methodes. In this way, the potential of each individual material can be used in the best way possible and thus implemented in an optimal structural design.
