| 中文摘要: |
| 采用中性盐雾条件模拟海洋大气环境进行了加速老化试验， 研究了碳纤维环氧复合材料在海洋气候中的耐久性。分析了该复合材料经盐雾老化试验后的质量、 层间剪切强度和弯曲强度的变化， 结合湿热老化机理， 研究了其老化规律。结果表明， 随着试验时间的增加， 复合材料的吸湿量增加， 力学强度下降，表现出塑性特征。在吸湿最初阶段对力学性能影响最大， 纵层间剪切强度和弯曲强度分别下降了10.3%和9.8%。 |

| Neutral salt fog spray of carbon fiber epoxy composite material was carried out to study the durability of the carbon fiber epoxy composite material in marine climate. The change mass, interlaminar shear strength and bending strength of the material after salt fog spray test was analyzed combined with heat aging mechanism. The results showed that with the test time increases, the moisture absorption of the material increases, mechanical strength decreases, and the material shows plastic characteristics; moisture absorption has significant influence on mechanical properties at primary phase; the interlaminar shear strength and bending strength decreased 10.3%, 9.8% respectively. |
