Plastics are used more and more as a body material in tribological systems. In addition to the polymer matrix, a modern, tribologically optimized, plastic-based body material consists of a reinforcing component and internal lubricants at different length scales. The projects aim is to investigate the potential of a significant increase in the tribological performance of plastic-based hybrid materials without external lubrication in contact with a metallic sliding partner of 100Cr6 by endothermic reactions. The study focusses on the verification of the hypothesis, after which the effect can be used on the one hand to shift the load limits for plastic-based tribological systems by influencing the temperature balance and gaseous and solid reaction products to higher values and on the other hand the tribological usability of such systems to maintain a wide load range.The research project aims to explore the possibilities and limitations of the proposed approach using a combination of experiment, modeling and simulation.

塑料越来越多地用作摩擦系统中的主体材料。除了聚合物基体之外，现代的、经过摩擦学优化的塑料基车身材料还包含增强成分和不同长度尺度的内部润滑剂。该项目的目的是研究通过吸热反应显着提高塑料基混合材料的摩擦学性能的潜力，无需外部润滑，与 100Cr6 金属滑动件接触。该研究的重点是验证假设，一方面可以利用该效应通过影响温度平衡以及气态和固态反应产物到更高的值来改变塑料摩擦系统的负载极限，另一方面控制此类系统的摩擦学可用性，以维持较宽的负载范围。该研究项目旨在结合实验、建模和仿真来探索所提出方法的可能性和局限性。
