Analysis and modelling of the behaviour of plastics

Understanding the complex behaviour of plastics is an essential requirement for the successful design of plastic parts and processing processes. The properties of the material are not defined until the processing stage. 

We carry out research in the field of materials technology with the focus on the following aspects:

  • the influence of the material's components (e.g. additives, fillers),
  • the inner structure of the material (e.g. fibre orientations, crystalline structure),
  • the design and stresses affecting the material during use (e.g. in relation to time, temperature).


Aim of our research and development activities

The aim of our research and development activities is to analyse and model the behaviour of the material with regard to its suitability for a particular application. From this, we derive reliable data for a realistic prediction – i.e. related to the material and the load – of the part properties within the context of virtual product development. We model processing processes with the aim of contributing to process and mould design by simulation, and of simulating and specifically adjusting the processing-dependent material behaviour in the part.

Our focus is on thermoplastics and thermoplastic elastomers, thermosetting plastics and elastomers. Material combinations such as cohesive plastic/metal hybrids are also a subject of research. 

Ongoing research projects in the field of materials technology
