| 摘 要： | 利用声发射技术,对三维编织C/SiC复合材料在拉伸过程中损伤发展、演化进行了实验研究。实验采集了三维编织C/SiC复合材料拉伸过程的声发射信号。运用多参数分析法,分析了三维编织C/SiC复合材料拉伸损伤的声发射特性,宏观上揭示了材料拉伸损伤的发展、演化过程和规律。研究结果表明三维编织C/SiC复合材料拉伸损伤演化可被分为两个主要阶段,损伤初始阶段和损伤严重阶段。

| Abstract: | The acoustic emission technology (AE) was used to investigate the damage mechanism of 3-D braided C/SiC composite under uniaxial tensile tests. AE characteristic parameters were collected over the entire stress/strain curve. AE characteristic of 3-D braided C/SiC composite damage evolution was analyzed using multi-parameters analytical method. Features of 3-D braided C/SiC composite damage evolution were also found. Experimental results indicate that damage process includes two main stages: damage initiating period and badly damaged period. |
