Polymer Composites Technology

"For the automation of CFRP components, a differential design is almost unavoidable; the joining of individual elements is the future of the lightweight construction industry." Prof. Dr.-Ing. Michael Kupke

Your partner for joining dissimilar matrix materials

Our Competencies:

 

  • Characterization and production of dissimilar, joined, fiber-reinforced thermoplastics and thermosets at coupon level
  • Analysis (morphological, chemical, thermodynamic, mechanical) of the joints between the different materials

Our team ... 

 

... consists of engineers and materials scientists who work on issues and challenges in an interdisciplinary manner. It is complemented by students from various disciplines.

Interphase of a PEI duromer compound.
Optimization of the joining process using a DOE.

Our offerings for you

  • Material identification of suitable polymer joints
  • Elaboration and definition of the framework points for successful joining of the components
  • Production of joined test specimens at coupon level in collaboration with our partners
  • Characterization of the resulting joint (using DSC; optical examination with light microscopy, AFM, SEM, ....; tensile tests to measure mechanical properties, ...)
  • Design of Experiments (DoE) using statistical test planning to increase your efficiency for further characterization and optimization of the joining process
