From multifunctional material to system – composite materials allow a variety of functional properties to be combined with optimum structural performance. This makes them a key element of mechatronics and adaptronics, a rapidly advancing field of research today. The main challenge is to master the complex property profile of these materials along the entire development chain from design and production to system integration and testing of the finished component. This is where the research activities of the competence field Tailored & Smart Composites start: The focus is on understanding the relationships between structure, process, and the resulting properties of multifunctional composites.
We are working on the development of new methods for non-destructive testing of composite materials and we integrate sensors or actuators in fiber-reinforced components so that they can adjust adaptively to their environment. After their design by finite element methods, we can produce such materials using standard methods, process them into components or semi-finished products and comprehensively characterize both, the material properties and the special functions.
