复合材料损伤与断裂的动态无损评价

Dynamic Nondestructive Evaluation on Damage and Fracture of Composites

本文介绍声发射技术作为动态无损检测的有效方法评价纤维增强复合材料的损伤与断裂,其内容包括:评价纤维束丝的质量、层板的损伤与断裂,评价构件的结构完整性和预测玻璃钢气瓶的强度。

In this paper, the damage and fracture of FRP are evaluated by acoustic emission as a dynamic nondestructive testing technology. The contents include the evaluation of the quality of carbon bundle, damage and fracture of laminates, the evaluation of the structure integrity of assemblies and prediction of the burst pressure of GFRP bottles.
