“…For the surfaces polished by a sandpaper, the crests are chipped off during this processing, with the original troughs remaining, and thus it is reasonable for these two surfaces to have a larger negative Rsk ave . After friction is applied, however, their Rsk ave values reach closer to 0 again, which can be explained by the wear debris embedded into the troughs during the friction Topographies of the six surfaces [27].…”

The surfaces of fiber woven composites (FWCs), especially woven ceramic matrix composites (WCMCs), are obviously anisotropic. Many kinds of damage, which are different from traditional homogeneous materials, could be caused by the fabrication and machining process. The old surface evaluation system appropriate for isotropic materials is no longer suitable to WCMCs, thus causing many difficulties in terms of their wide industrial applications. This chapter presents a grading surface measurement and evaluation system for WCMCs based on their microstructures. The system includes four levels: fiber, fiber bundle, cell body, and the whole surface. On the fiber level, the typical forms of fiber damage, and their effects on the surface morphology of WCMCs are analyzed, which lays a foundation for the measurement and evaluation methods on the next three levels. On each subsequent level, the system proposes a set of surface measurement sampling parameter determination methods and surface quality evaluation methods based on the principle of statistics. As demonstrations, the surface measurement and evaluation on each level were processed on a carbon fiber-reinforced silicon carbide matrix composite (C f /SiC) to illustrate the methodology of the system.

“…The ultimate purpose is to accurately establish the bridge between surface processing, topography and the material utilization property. The measurement and evaluation on fiber bundle scale has been studied in [14,15], and the measurement at cell body and the whole surface scales have also been researched. This paper is the last one as a series of surface assessment of an LFRWC focusing on the evaluation of friction and wear property at the whole surface scale.…”

Multi-scale measurement and evaluation of long fiber reinforced woven composites (LFRWCs) is to accurately establish the bridge between surface processing, topography and material utilization property. This paper mainly focuses on the evaluation of friction and wear property of the whole surface of an LFRWC. The friction performance of one type of LFRWC, namely carbon fiber reinforced silicon carbide composite (C/SiC) pin, rubbing with ZrO 2 disc is researched under two situations: the first is the processing angle of C/SiC is changed and the processing parameters are constant; the second is the processing angle is constant but the surface is polished by different sandpaper grits. The purpose is to find the main factors to evaluate the friction performance of an LFRWC. The results show that the surface microstructure of the cell body from a qualitative perspective combining the action of the area ratios of different fiber bundles from a quantitative perspective in the first situation, and surface topography parameters in the second situation are the primary influence factors. Contacting interface scale is the dominating mechanism. This research is a fundament for the precise evaluation and prediction of the friction performance of an LFRWC.

Due to the special structure of the woven ceramic matrix composites, challenges and difficulties in the grinding process gradually emerge. How to ensure the reasonable and reliable application of materials has become a hot topic in the present research. The force model is beneficial to understand, predict, and even control the machining process. This chapter investigates the grinding force and process optimization of woven ceramic matrix composites, especially grinding force modeling, surface quality and process optimization of woven ceramic matrix composites during grinding. A new force model considering the fiber orientation of WCMC is developed based on the energy balancing theory. Through the construction of a mathematical model, the study demonstrates the correlation of grinding force with the processing parameters and the composite fiber orientation. The optimum process parameters were obtained by aiming at minimum grinding force and maximum surface quality. The results show that the predictable model has good consistency with the experimental results, and fiber orientation has a major influence on the grinding force. This research can be used to predict the grinding force, thus conducting the machining and controlling their processing quality.
