Solid particle erosion (SPE) is an issue for aircraft exposed to hard, fine particles, such as sand or dust, that can be ingested into the engine at a high velocity without reaching their melting point, resulting in material removal. SPE can be attributed to the intake of particulate debris from the runway or from airborne particulates. The cumulative mass loss from SPE damage affects the structural integrity and performance of the engine; however, its effects on ceramic matrix composites (CMCs), that are being employed in the aerospace industry, are not well understood in literature. The limited SPE research studies that have been published are primarily based on woven silicon carbide (SiC)-based CMC architectures. Therefore, the aim of this study was to characterize the effects of ambient temperature SPE damage on the mechanical properties of a SiC-based cross-ply laminate CMC system. The effects of erodent particle velocity and cumulative erodent particle mass were quantified with respective to the damage morphology and retained tensile strength.
