| 摘 要： | 通过声发射技术(Acoustic Emission简称AE)对三维编织C/SiC复合材料试件单向拉伸实验过程进行全程动态监测,利用声发射特征参数的综合分析法揭示了三维编织C/SiC复合材料单向拉伸时损伤演化过程和规律。实验结果表明三维编织C/SiC复合材料单向拉伸时损伤发展的四个阶段及声发射特性并利用声发射相对能量定义了材料临界损伤强度。

| Abstract: | 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. |
