| 摘 要： | 采用超高压浸渍-炭化方法制备了沥青基C/C复合材料,并对其在1273～1773 K氧化后的力学性能进行了测试,借助扫描电镜研究了该材料的氧化形貌.实验结果表明,在恒温下,随着氧化时间的延长,试样弯曲强度和模量逐渐减小,弯曲强度和模量与时间呈线性关系;而在恒定时间条件下,随着氧化温度的升高,试样的弯曲强度和模量亦逐渐减小...

| Abstract: | Pitch-based C/C composites were prepared by using super high pressure impregnation and carbonization process,and the mechanical behaviors of the samples were investigated at different temperatures(1 273~1 773 K),Then the oxidation morphology of the samples was studied by SEM(scanning electron microscopic).The experimental results show that the flexural strength and modulus of samples are linearly decreased with the increase of oxidation time under constant temperature,but nonlinearly decreased with the incr... |
