摘要
将小波包能量谱分析法应用到碳纤维复合材料层合板(CFRP层合板)中,对CFRP层合板的落锤冲击实验过程进行分析,得到CFRP层合板在冲击实验时的损伤类型和各损伤阶段所呈现出来的声发射信号特征,实现材料损伤类型的判别。
Having wavelet packet energy spectrum analysis method applied to carbon fiber composite laminates(CFRP laminates)was implemented to analyze drop weight impact test process of CFRP laminates so as to obtain damage types of the CFRP laminates in impact test and the acoustic emission signal characteristics in each damage stage and to identify material damage types.
