Characterizing Damage Evolution of Three-dimensional Braided C/SiC Composite with AE Technology
声发射技术在三维编织C/SiC复合材料拉伸损伤分析中的应用

An approach toanalyze the tensile behavior and damage evolution of three-dimensional braided C/SiC composite.Monotonic tensile tests were performed. Acoustic emission (AE) was used to monitor damage extension during test.Damage evolution was analyzed and different damage phases were determined by AE characteristic parameters data. Critical damage stress described with AE cumulates energy waw also defined.
