摘要(Abstract)：

采用扫描电镜(SEM)、环向拉伸与硬度法观察并测试H_2S与CO_2环境下渗透后DN100玻璃钢试样的形貌以及力学性能。结果表明,与未渗透试样相比,渗透实验后玻璃钢管内表面缺陷较多,存在大量腐蚀坑;环向拉伸时,55℃渗透后玻璃钢管外层与中间层断裂比较整齐,但内层撕裂;85℃渗透后玻璃钢管外层与内层先开裂,中间层后开裂。渗透后玻璃钢中环氧树脂粉化严重,与纤维脱粘,缺陷孔隙深度增加,85℃时更为明显。55℃、85℃渗透后试样的环向拉伸峰值拉力、巴氏硬度保留百分数以及玻璃化转变温度分别为27.381 kN/26.643 kN、92.5%/86.25%、136.30℃、134.37℃。
