Abstract In order to deeply reveal the influencing factors of the antioxidative property of 2D-C/SiC composites, matrix cracking and interfacial debon-ding damages were introduced by preloading for two kinds of 2D-C/SiC materials with different density, and then static oxidation experiments were conducted respectively at 700 ℃, 900 ℃ and 1 100 ℃. Subsequently, the residual tensile strength experiment was performed at room temperature to investigate the effects of density, microscopic damages and temperature on the oxidized residual modulus and strength of the mate-rials. The experimental results show that both materials present different degrees of softening and weakening phenomena after high-temperature oxidation, and the fiber pullout became longer. It is also shows that the mechanical property attenuation of the materials is positively correlated with the oxidation temperature and the microscopic damage produced by the preloading. The microscopic damage of the material B was more serious compared to that of the higher-density material A, and its property degradation after oxidation was even greater. With the rise of oxidation temperature, both materials underwent fracture mode transitions. For the lower-density material B the mechanical properties decayed most se-riously after oxidation at 900 ℃, with tensile strength and modulus loss rates as high as 59.5% and 29.8%, respectively. The correlation between the residual properties and the fiber pullout length suggests that interfacial weakening is a very serious problem for 2D-C/SiC composites containing microscale damage when serving in high-temperature oxidative environments. Finally, the residual tensile strength properties of the two 2D-C/SiC materials were analytically characterized using a physico-chemical mechanisms based multiscale strength model, which revealed the key microscale factors of the oxidation damage and meanwhile accurately predicted the residual tensile strength of the materials.
