研究T800碳纤维/环氧树脂基复合材料在海水环境中进行湿热腐蚀老化,将制备好的试件放置在人工制备70℃,3.5% NaCl溶液中腐蚀30,60,90d,通过质量变化、老化前后表面形貌、红外光谱、动态力学性能、压缩实验和层间剪切实验分析材料的力学性能变化。结果表明:T800碳纤维/环氧树脂复合材料在3.5% NaCl溶液中吸湿率分别为0.39%,0.47%,0.53%;未老化试样纤维与基体之间黏结良好,在3.5% NaCl溶液老化后纤维与基体界面破坏随时间的增加老化更加严重;玻璃化转变温度Tg下降,分别在老化30,60,90d后从189.16℃下降到177.54,171.88,168.06℃;经3.5% NaCl溶液老化后,老化30,60,90d试样的最大破坏载荷分别降低3.2%,8.4%,15.3%,压缩强度分别降低3.0%,8.2%,15.9%;层间剪切最大破坏载荷分别降低3.0%,9.2%,14.9%,剪切强度分别降低3.0%,9.7%,16.4%。 |

The hygrothermal aging of T800 carbon fiber/epoxy resin composites in seawater environment were studied.The prepared specimens were immersed in artificial seawater 70℃,3.5% NaCl solution for 30,60and 90days for corrosion.The mechanical properties of the materials were analyzed by mass change,surface morphology before and after aging,infrared spectroscopy,dynamic mechanical properties,compression test and interlayer shear test.The results show that the moisture absorption rate of T800carbon fiber/epoxy resin matrix composites in 3.5% NaCl solution is 0.39%, 0.47%,0.53%.Good adhesion between unaging sample fiber and matrix,and the damage of the interface between the fiber and the matrix become more serious with the increase of time after aging in 3.5% NaCl solution.The glass transition temperature(Tg)is decreased from 189.16℃to 177.54, 171.88℃and 168.06℃after 30,60and 90days aging.After aging with 3.5%NaCl solution,the maximum compressive failure load of specimens for 30,60and 90days is decreased by 3.2%,8.4% and 15.3%,respectively,and the compressive strength is decreased by 3.0%,8.2% and 15.9%, respectively. The maximum interlaminar shear failure load is reduced by 3.0%,9.2%and 14.9%, and the shear strength is reduced by 3.0%,9.7%and 16.4%,respectively. |
