Research profile

Overview Research Fields

For high-volume, cost and resource efficient production, in-line and in-situ processes are an important factor. At the moment, there are no process chains, design principles or calculation methods allowing for a continuous production in series, which is why the desirable wide and promising use of high-volume technologies for lightweight structures keeps getting restrained.

For fundamentally optimized material development that are, both technological as well as material engineering issues have to be solved. Therefore the cooperation across scientific disciplines in development, manufacturing, characterization, modelling and simulation is necessary. Additionally, mature technologies have to be made available to the competitive market as prototypes and implemented in industrial contexts via technology transfer.

Manufacturing process chains in mass production call for efficient processing technologies concerning the matrix systems. Therefore thermoplastic polymers are ideal. Consequent lightweight manufacturing has to be implemented according to the respective demands, be highly efficient and adaptable in its manufacturing. The combination of fibre-reinforced plastics and metals or ceramics has high potential in this regard. Manufacturing such multifunctional structures in one adaptive process step – possibly in series – using physical modes of actions during manufacturing of the base technologies in the processing of plastic, metal and ceramics, equals a paradigmatic change in the application of multicomponent systems.

Prospectively, the Endowed Chair will focus on 3 closely connected main research domains, strictly following the steps from fundamental research via applied research to industrial implementation.

Textile-based polymer matrix composites
  • Developing new 3D architectures for lightweight structures in mass production (sandwich composites)
  • Creating compatibility between material and process in textile-based manufacturing
  • Reproducible relations between structure and properties of textile plastic composites in mass-production
  • Designing textile composites with regard to components and load
  • Developing textile reinforcing structures adapted to the respective process, with differentiated or refined structure and functional density
  • Developing solutions for recycling
Functional multi-hybrid material composites
  • Developing and designing innovative material combinations in multi-hybrid laminates (tex-tile/FRP/metal/ceramics/functional integration) with regard to load and demands and the respective specific use, as so called tailor-made composites, manufactured in-line
  • Variety of options thanks to modular system, integrating recycling concepts
  • Interface design
  • Manufacturing and integrating the powder metallurgy of metal composite powders for subsequent consolidation processes (HIP, extrusion, injection moulding (MIM), 3D solutions (additive manufactur-ing etc.))
Mass production technologies for ceramic composites
  • Using the advantages of fibre-reinforced ceramics regarding their outstanding performance as opposed to monolithic ceramics (fracture toughness, damage tolerance, shock load resistance, resistance against corrosion, wear and thermal shock, lifespan) for new applications and markets
  • Developing a reproducible process chain from thermoplastic processing to the thermoset moulded body for pyrolysis and silication of non-oxide CMCs
  • Developing innovative cost-efficient and reproducible manufacturing processes for non-oxide and oxide fibre-reinforced ceramics
  • Tailor-made processing structure design, fibre/matrix-design, tailor-made CMCs
  • Realizing complex geometries (injection moulding) and profiles (extrusion)
  • Integrating coupled multi-criteria structural and procedural simulations
