Tailored Thermosets & Biomaterials

New matrices and fiber reinforced composites with multifunctional properties are key elements for future technological applications. Focussed are the research, development and understanding of properties of thermosets, polymer hybrids, nanocomposites and biomaterials.

Their properties are tailored via additives, fillers, reinforcements (micro, nano) and fibers (carbon, glass, basalt, natural fibers) to reach high material performance and structural integrity. Various functionalities are permanently made available or activated as required. Nanotechnology is utilized in order to modify polymers e.g. via commercial nanoparticles and functional capsules. With specific emphasis on eco-efficiency, the process related properties are adapted and fundamental relationships between materials’ processing, the resulting structures and properties are explored and basic know-how is transferred into applications. As well the principles of biological structures are focussed.
