摘要

摘要: 先进的陶瓷基复合材料具有耐超高温、抗腐蚀、高的比强度和高的比刚度等优异性能，是新一代高超声速飞行器热防护材料和结构的重要候选材料.然而，陶瓷基复合材料复杂的微观结构和多种损伤机制使其本构研究面临诸多挑战.Mini复合材料是多尺度研究中的重要桥梁，研究其力学性能对先进陶瓷基复合材料的研发和服役安全可靠性评价具有重要意义.基于间接感应加热技术，首次开展了惰性环境2 200 ℃下C/PyC/SiC mini复合材料拉伸性能测试，揭示了陶瓷基复合材料在服役超高温极端环境下的塑性变形行为.采用三参数Weibull概率统计模型表征基体的随机开裂，通过剪滞模型计算纤维和基体中的应力分布，考虑纤维束的超高温非线性变形和残余热应力影响，建立了C/PyC/SiC mini复合材料超高温塑性细观本构模型，并将理论预测结果和实验结果对比，对模型进行了验证.该研究不仅能够丰富陶瓷基复合材料的力学理论体系，还将为其在高超声速飞行器上的服役可靠性评估和寿命预测提供实验和理论支撑.

Abstract: Advanced ceramic matrix composites have excellent properties, such as resistance to ultra-high temperatures and corrosion, as well as high specific strength and stiffness. They are important candidates for thermal protection materials and structures of new-generation hypersonic vehicles. However, ceramic matrix composites have complex microstructures and various damage mechanisms, which make the study of their constitutive relations challenging. Minicomposites are the critical link in the multi-scale study of ceramic matrix composites. The study on their mechanical behaviors is important to the development and evaluation of security and reliability of advanced ceramic matrix composites. The tensile properties of C/PyC/SiC minicomposites were measured at 2 200 ℃ in inert atmospheres for the first time based on the indirect induction heating technology. The plastic deformation behaviors of ceramic matrix composites under ultra-high-temperature extreme environments were revealed. The random cracking of matrix was characterized by a 3-parameter Weibull model. The stress distributions of fiber and matrix were calculated based on the slip-lag model. The effects of ultra-high-temperature nonlinear deformation of fiber bundles and residual thermal stresses in the composites were characterized. An ultra-high-temperature plastic mesoscale constitutive model was established for C/PyC/SiC minicomposites and verified. The study is useful for the development of mechanics for ceramic matrix composites and provides experimental and theoretical supports for the reliability evaluation and life prediction of ceramic matrix composites on the hypersonic vehicles.
