Oxidation behaviors of carbon fiber reinforced multilayer SiC-Si3N4 matrix composites

open access: yesJournal of Advanced Ceramics, 2022
Oxidation behaviors of carbon fiber reinforced SiC matrix composites (C/SiC) are one of the most noteworthy properties. For C/SiC, the oxidation behavior was controlled by matrix microcracks caused by the mismatch of coefficients of thermal expansion ...
