Tailored Thermosets & Biomaterials

The competence field Tailored Thermosets & Biomaterials performs research and development on composite materials with functional properties based on thermosetting polymers, bio-polymers, hybrid systems, and nanocomposites. We make use of bio-based, sustainable resources wherever it is technically, economically and ecologically reasonable. Targets are the continuous adaption and improvement of materials and the integration of multiple functionalities within one specifically customized composite. Requirements are e.g. high modulus, strength and excellent damage tolerance, flame resistance, electrical conductivity, heat/sound/corrosion protection, barrier effect, low wear, intrinsic lubrication, and recyclability.

We work on solutions to replace toxic polymer solvents by non-toxic versions. New materials are applied e.g. as composites, foams, bulk resins, and coatings. We apply nanotechnology to reinforce polymers by in-house synthesized or commercially available nanoparticles. In order to avoid dispersion efforts and reduce processing costs, we apply innovative polymers which generate micro and nanostructures in-situ during the manufacturing process, thereby creating improved material properties.
