Approach for investigation of CFRP tribological stressed interfaces through levels of abstraction

Carbon Fiber Reinforced Plastics (CFRP) offer high lightweight potential, particularly for dynamic machine components due to their strength-to-weight ratio and low thermal expansion. However, integrating CFRP into stressed interfaces, such as tool spindles, poses challenges like anisotropic properties and tribological complexity. This study presents a multi-level approach to investigate and transfer tribological parameters in CFRP systems. Using the hierarchical product component test pyramid, it bridges product, structure and meterial levels, e.g. through simplified block-on-plate, as well as block-on-tube tests. Through abstracted and application-oriented test setups, key influencing factors can be identified and analyzed. The hierarchical test pyramid allows for stepwise knowledge transfer between abstraction levels, reducing testing effort without sacrificing relevant information.
