摘　　要：通过制作纤维缠绕标准容器试样,并对部分试样表面纤维制作人工损伤,与标准容器试样比较爆破压力,并进行有限元分析、研究其破坏机理,对强度影响程度进行评估。结果表明:表面纤维损伤会造成压力容器在应力水平较低情况下局部发生层间剪切破坏,损伤容器爆破强度平均值降低22.4%,损伤修复后的容器爆破强度降低12.2%。By making samples of the filament winding composite standard pressure vessels, we make contrived fiber damages on the surface of part of samples, and then we compare the bursting pressure with the uncontrived samples. We ana- lyze the mechanics of damage with FEA, and evaluate the damage level of strength. The results shows that the fibre damage on surface may induce the interlaminar shearing failure of the pressure vessels partially at the low stress level, and average bursting strength of the damaged samples is reduced by 22.4% ,bursting strength of the damaged samples that was repaired is reduced by 12.2%.
