摘　　要：复合材料气瓶具备质量轻、强度高、耐腐蚀与疲劳性能好等优势,但目前针对复合材料气瓶检验的国家标准主要以宏观检查为主,内外表面缺陷以及缠绕层的内部缺陷难以检出。分析了内部缺陷对复合材料气瓶的影响,对比并分析了3种缠绕层内部缺陷的检验方法,以期为复合材料气瓶的定期检验提供一定参考。Composite gas cylinders have the advantages of light weight,high strength,good corrosion resistance and fatigue performance,but the current national standards for composite gas cylinders are mainly based on macroscopic inspection,searching for internal and external surface defects.Inner defects of winding layer cannot be detected.In this paper,the influence of inner defects on composite gas cylinders was analyzed.Three kinds of testing methods for inner defects of winding layer were compared to provide reference for periodic inspection of composite gas cylinders.
