The interplay of material development, process engineering, tooling, and precise control of critical processing parameters is key to successful process innovations. At our institute, we combine numerical simulations with experimental methods in a fully equipped pilot plant to develop novel materials, processes, and products. We merge nanotechnology with traditional plastics and composite technologies to deliver high-performance, functional, and economically viable solutions.
