Life‐Limiting Behavior and Life Management of SiC‐Based Composites

A 2D image-based multiphysics model for lifetime evaluation and failure scenario analysis of self-healing ceramic-matrix mini-composites under a tensile load

“…The cracks allow the diffusion of oxygen, which can reach the fibres and cause their oxidation, with subsequent degradation of their mechanical properties. Hence, the need to minimise the oxygen diffusion in the material as much as possible to avoid its degradation and the consequent rapid failure [9]. Self-healing processes [10] are essential to pursue this goal, allowing CMCs to exhibit an extremely long lifetime [11,12].…”
