Investigation on the tribological properties of recycled carbon fiber reinforced polymer-based tribocomposites and their simulation-supported optimization

节约能源对于缓解当前的能源危机至关重要，除了改变能源系统外，还可以阻止气候变化。在工业生产中，可以大大节省能源，在塑料工业中，通过回收和再利用，也可以节省来自化石资源的物料流。这一后续提案建立在其成功的第一个资助阶段的基础上，在第一个资助阶段，该战略通过使用再生碳纤维（rcf）生产具有优异摩擦和磨损性能的聚合物基摩擦材料取得了成功。这种制造高性能摩擦材料的战略是通过使用可回收材料（rPEEK和rcf）来继续的，这是高能效和环保的。在成功的模型试验的基础上，该项目的科学目标是从根本上进一步研究成分方面的各种修改，特别是纤维/基体和纤维/颗粒的相互作用，以及研究和可靠地评估接近组件的几何形状的化合物的行为，如推力垫圈和滑动轴承。通过数值模拟确定的接触温度，可以在不同的试验设备上对钢作对体系统中材料的摩擦学性能进行研究。一个成功的项目不仅将有助于理解由回收材料制成的摩擦复合材料的摩擦和磨损行为，而且还将为基于材料可持续性和循环经济的领域回报的摩擦材料的开发和使用铺平道路。

Saving energy is essential to mitigate the current energy crisis and, in addition to transforming the energy system, to stop fueling climate change. In industrial production, energy can be significantly saved, and in the plastics industry, material flows from fossil resources can also be saved through recycling and reuse. This continuation proposal builds on its successful first funding phase, in which the strategy succeeded by using recycled carbon fibers (rCFs) to produce polymer-based tribomaterials with excellent friction and wear properties. This strategy for manufacturing of high-performance tribomaterials is continued by using recycled materials (rPEEK and rCFs), which are highly energy efficient and environmentally friendly. Building on the successful model tests, the scientific objectives of this project are to fundamentally further investigate various modifications with respect to composition and, in particular, fiber/matrix and fiber/particle interactions, as well as to investigate and reliably assess the behavior of the compounds in geometries close to the components, such as thrust washers and plain bearings. It is postulated that the tribological properties of the materials in the system with steel as a counterbody can be carried out in different test facilities by means of the contact temperature determined by numerical simulation. A successful project will not only contribute to the understanding of the friction and wear behavior of tribocomposites with significant proportions made from recycled materials but also pave the way for the development and use of tribomaterials based on returns from the field in terms of materials sustainability and circular economy.
