ACOUSTIC EMISSION CHARACTERISTICS OF DAMAGE PROCESS FOR APMOC/EPOXY COMPOSITE LAMINATES
-
摘要: 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。

Abstract: A detailed study of damage mechanism failure process for APMOCiepoxy composite laminates in different stacking sequences was conducted by use of acoustic emission monitoring. The results showed that the relationship between AE signal parameters and damage mechanisms can be established. Obviously,AE signal parameters being recorded can reveal the dynamic damage process of the laminates. The different AE parameters relate to the different damage process and mechanisms in the laminates.-
