摘要
简述了复合材料AE技术的发展概况、AE特性和破坏类型;讨论了几种不同破坏机理的AE判据;着重介绍了AE技术在复合材料压力容器无损检测中的应用及压力容器水压试验时应注意的某些问题。
General situation of the progress on acoustic emission (AE) technique forcomposite materials is briefly described and several AE criteria concerned with the differ-ent failure mechanisms are discussed in the paper. The emphasis is laid on the presenta-tion of application of AE technique to nondestructive test on pressure vessels made ofcomposite materials and some problems that should be paid attention to during the wat-er tests of pressure vessels.
