Research Progress on In-situ Monitoring of Damage Behavior of SiCf/SiC Ceramic Matrix Composites at High Temperature Environments
摘要
Abstract
Continuous SiC fiber-reinforced SiC(SiCf/SiC)composites possess high specific strength,high specific modulus,high-temperature resistance,and radiation resistance,making them suitable for applications in hot-end parts of advanced aero-engines and claddings of nuclear reactors.SiCf/SiC composites are composed of fibers,interfaces and matrix,endowing them with complex multi-scale structural characteristics.These composites are designed to serve in harsh environment,and their damage and failure process are complex.A profound understanding and accurate analysis of damage and failure mechanisms of SiCf/SiC composites under service environments are of great significance for the optimized design of materials and the reliable service of components.Traditional"post-mortem analysis"methods are incapable of acquiring data during the damage and failure process of materials under complex service environments.Therefore,there is an urgent need to develop in-situ characterization techniques for composites under high-temperature service environments.This paper reviewed the principles,advantages,and limitations of in-situ monitoring methods based on scanning electron microscopy,digital image correlation,micro computational tomography,acoustic emission,and electrical resistance.It focused on the latest research progress in the high-temperature mechanical characterization of SiCf/SiC composites using various in-situ monitoring methods and combinations thereof.It summarized the challenges in the in-situ monitoring technologies of SiCf/SiC composites under high-temperature environments and provided a preliminary outlook on the future development directions,such as the combined use of multiple in-situ monitoring techniques,new detection technologies like terahertz radiation,and in-situ damage monitoring methods for complex components.关键词
