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。除了聚合物基体外，一种现代的、摩擦学优化的塑料车身材料还包括不同长度范围的增强成分和内部润滑剂。该项目的目的是研究在没有外部润滑的情况下，通过吸热反应与100Cr6金属滑动伙伴接触，显著提高塑料基混合材料摩擦学性能的潜力。研究的重点是验证假设，在此之后，一方面可以使用该效应来改变塑料的载荷极限，通过影响温度平衡和气体和固体反应产物的更高值，另一方面，这种系统的摩擦学可用性，以保持广泛的负载范围，该研究项目旨在探索的可能性和局限性的建议采用实验、建模和仿真相结合的方法。
