摘　　要：通过薄壁金属内衬的外压强度试验、不同缠绕张力NOL环以及复合材料气瓶的力学性能试验,采用声发射的检测方法研究缠绕张力对薄壁金属内衬复合材料气瓶的疲劳以及爆破性能的影响。结果表明,薄壁金属内衬的外压强度较小,缠绕张力对复合气瓶的疲劳以及爆破性能影响较大,采用声发射信号以及气瓶的性能试验研究可以指导制定最优化的缠绕张力制度。In order to study the influence of winding tension to the mechanical properties of metal inner lining composite gas cylinder,the NOL ring samples and composite gas cylinders were fabricated by different winding tensions. The fatigue and abruption tests were carried out,which were followed by acoustic emission test. Moreover,the external pressure of the thin wall metal inner lining was also tested. The results indicated that external pressure of the thin wall metal lining（ 1. 4mm） was low. Winding tension presented great impact on the fatigue properties and blowing up pressure of the composite gas cylinders. Water pressure experiments and acoustic emission test could be used to frame the best winding tension of the gas cylinders.
