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.

拟议项目旨在通过使用随时间变化的输入变量（载荷序列），减少金属/ FRP摩擦系统中聚合物基摩擦材料的制备、优化和鉴定所需的极高时间和材料支出。其主要目的是澄清短期测试与不同的负载是否是一个合适的方法，有效地检测热和机械载荷极限，并最终有助于有效的表征和开发的聚合物基摩擦材料。最后，摩擦磨损特性与磨损机理的相关性以及聚合物基体中温度分布的模拟将为聚合物基摩擦材料的材料组成优化提供重要的指导，并将用两种不同的聚合物基体对相关性进行验证（聚醚醚酮PEEK（半结晶）和聚醚砜PESU（无定形）），具有不同长度尺度上的不同填料。
