研究了化学气相渗透法制备的2DC/SiC螺栓在模拟再入大气层环境中的拉伸性能和氧化行为。结果表明，2D C/SiC螺栓在1300、1600和1800°C的试验温度下的抗拉强度分别下降，在室温下保留了85%、92%和94%的原始性能。在1300 ~ 1800°C范围内，随着试验温度的升高，2D C/SiC螺栓的抗拉强度和断裂时间略有增加。显微组织观察表明，C/SiC螺栓在1300°C低温下比在1800°C高温下更容易发生纤维端部钝化的反应控制氧化，从而导致严重的力学性能退化和严重的氧化。
The tensile properties and oxidation behavior of 2D C/SiC bolts prepared by chemical vapor infiltration were investigated in a simulated re-entry environment. The results showed that all the tensile strengths of 2D C/SiC bolts at test temperatures of 1300, 1600 and 1800°C decreased, respectively, retaining 85%, 92%, and 94% of the virgin properties at room temperature. The tensile strengths and times to failure of 2D C/SiC bolts slightly increased with increase of test temperature from 1300 to 1800°C. Microstructural observations indicated that the C/SiC bolts at lower temperature of 1300°C were more susceptible to the reaction-controlled oxidation with the blunt fiber ends than those at high temperature of 1800°C, which resulting in turn in great mechanical degradation and severe oxidation.
