Mechanical behavior and damage evolution of SiC/SiC composites induced by wear damage
Source abstract
Abstract
The wear mechanism and tribological properties of plain-woven SiC/SiC composites were analyzed initially under varying loads, speeds, and temperatures. Subsequently, the effect of wear damage on the tensile strength and failure mechanisms of SiC/SiC composites was systematically investigated using the acoustic emission technique (AE) and digital image correlation (DIC). The correlation between the AE parameters and damage modes of SiC/SiC composites with wear damage was established by pattern recognition. Analysis revealed that crack propagation and matrix cracking occurred in the worn regions during the initial stages of tensile loading. This localized damage caused significant uniformity differences in the strain filed between worn and unworn areas, predisposing the worn regions to through-crack initiation and ultimate failure.
