The proposed project aims to reduce the extremely high time and material expenditures for the preparation, optimization and qualification of polymer-based tribomaterials in metal / FRP tribosystems by using time-dependent input variables (load sequences). The main aim is to clarify whether short-term tests with varying loads are a suitable approach for detecting thermal and mechanical load limits effectively and finally contribute to an efficient characterization and development of polymer-based tribomaterials. Ultimately, the correlation of the friction and wear characteristics with the wear mechanisms in combination with the simulation of the temperature distribution in the polymer-based body should provide important indications for the optimization of the material composition of polymer-based tribomaterials.The verification of the correlations will be investigated with two different polymer matrices (polyetheretherketone PEEK (semi-crystalline) and polyethersulfone PESU (amorphous)) with different fillers on different length scales.
