| 摘要: |
| 为了研究不同铺层对TG800/E207碳纤维环氧树脂复合材料吸湿特性和拉伸性能的影响，制备了[0]16，[90]16，[±45]4s和[+45/0/0/-45/-45/0/0/+45]s 4种铺层的复合材料层板，分析了复合材料在80℃，90%RH环境中的吸湿动力学曲线、吸湿损伤形貌、破坏形貌、载荷位移曲线及其强度退化。结果表明：TG800/E207复合材料层板的吸湿曲线呈现多阶段现象。当吸湿时间达到1 608 h时，吸湿趋于平衡；[90]16的吸湿量最低，其最终吸湿量仅为0.806%；[+45/0/0/-45/-45/0/0/+45]s的吸湿量最高，其最终吸湿量为0.876%。与室温干态（RTD）条件下相比，室温湿态（RTW）条件下这4种铺层复合材料层板破坏载荷分别降低了13.80%，27.36%，10.70%和25.60%。[90]16的最终吸湿量最低但其拉伸强度退化最为严重。 |

| Abstract: |
| [0]16,[90]16,[±45]4s and[+45/0/0/-45/-45/0/0/+45]s were fabricated to study the influence of the different ply lay-up on the moisture absorption and tensile properties of TG800/E207 carbon fiber epoxy resin composite laminates at a hygrothermal environment of 80℃ and 90%RH. Moisture absorption curves, damage morphology after moisture absorption, fracture morphology, load-displacement curves and strength degradation were analyzed. The results show that the moisture absorption curves of TG800/E207 composite laminates present multi-stage phenomenon. The moisture adsorption reached equilibrium at a moisture absorption time of 1 608 hours. The equilibrium moisture content of[90]16 is the lowest and its saturated moisture content is only 0.806%; the equilibrium moisture content of[+45/0/0/-45/-45/0/0/+45]s is the highest and its saturated moisture absorption rate is 0.876%. The failure load of[0]16,[90]16,[±45]4s and[+45/0/0/-45/-45/0/0/+45]s samples decreased by 13.8%, 27.36%, 10.7% and 25.6%, respectively. The saturated moisture absorption of[90]16 is the lowest, but its tensile strength degradation is the most serious. |
