| Abstract: |
| With ceramic matrix composites toughened with short carbon fiber, continuous carbon fiber and silicon carbide fiber as the objects, the experiment studies on the influences of interface layer on the failure mode of FTCMCs in recent years were reviewed. From the building of microscopic, mechanics model and analysis on multi-scale damage, mechanical property simulation and analysis methods for FTCMCs on the interface layer were summarized The establishment of practical physical model and the development of more advanced multi-scale analysis method were proposed to solve the complex performance characterization problem of FTCMCs under service environment in an effective way. The performance of FTCMCs in complex service environment was characterized and optimized through the multi-field coupling and multi-scale modeling analysis method to systematically reveal the corresponding relationship between the microstructure of interface layer and the performance of macro composites, to further guide the process design. All is the key research direction for future fiber toughened ceramic matrix composites interface layer. |
