摘　　要：通过对十个碳纤维复合材料气瓶的声发射检测试验研究,初步探索了平面定位技术、费利西蒂比对复合材料气瓶工艺质量和损伤严重性评价的可行性,同时还摸索了复合材料气瓶压力循环疲劳过程的声发射特性。研究认为:声发射作为复合材料气瓶工艺质量和损伤严重性评价方法是可行的,平面定位结果和疲劳试验结果对气瓶质量评价有一定的辅助作用,声发射费利西蒂比值越高则气瓶损伤严重性越低。Ten C/E composite pressure vessels were testing by acoustic emission technique to research the Feasibility of evaluating the craft quality and damage seriousness by Δt-location and the Felicity ration.In addition,the fatigue test of the C/E compostie pressure vessels were examined by the acoustic emission technique.The results show that the acoustic emisson technique is feasible to evaluating the composite pressure vessel and Δt-location and fatigue test are the assistant function for evaluation.Damage of the vessel is more serious as the Felicity ratio is bigger.
