本文利用声发射测试技术,对APMOC/环氧复合材料各种铺层的单层板、层合板的损伤机理和破坏过程进行了详细的研究。结果表明,在不同的声发射信号参量特征与不同的损伤机理之间存在对应关系。声发射信号参量的变化过程能够描述层板的动态损伤过程,不同的声发射参量表征层板的不同损伤过程与机理。
In this paper, the acoustic emission testing technique was used to study the damage mechanism and failure process of various laminated APMOC / epoxy composite laminates. The results show that there is a correspondence between different acoustic emission signal parameters and different damage mechanisms. The process of AE signal parameters variation can describe the dynamic damage process of laminates. Different acoustic emission parameters characterize the different damage processes and mechanisms of laminates.
