摘要

通过对碳纤维环氧复合材料试样进行不同湿热环境下的拉伸和压缩实验，分析其吸湿特性、拉压力学性能、破坏后断口形貌以及动态力学性能，探讨湿热对该复合材料的拉伸和压缩性能的影响。结果表明：碳纤维环氧复合材料的吸湿过程满足Fick定律，饱和吸湿率约为0.86%。吸湿后材料表面变得光滑，有少量纤维拔出和树脂破坏发生，但吸湿后没有发生化学反应和新物质生成。吸湿后在130℃下，复合材料的拉伸性能保持率为96%，而压缩性能保持率仅为69%。吸湿后玻璃化转变温度比干态时下降了33℃。

Abstract：

The tensile and compressive tests on woven carbon fiber epoxy resin composite specimens in different hygrothermal environments were carried out. The moisture absorption, tensile and compressive properties, fracture morphology and dynamic mechanical properties were analyzed. The influence of hygrothermal environments on tensile and compressive properties was investigated. The results show that the absorption process of carbon fiber epoxy composites satisfies Fick's law, and its saturated moisture absorption rate is about 0.86%. After moisture absorption, the surface of specimens becomes smooth, the phenomenon of few fibers pull-out and resin damage occurs, but no chemical reaction and no new substances is generated. After moisture absorption at 130℃, the retention rate of tensile properties is 96%, but the retention rate of compression properties is only 69%. The glass transition temperature of composite laminates after moisture absorption decreases by 33℃ compared with that in dry state.

Key words： carbon fiber epoxy resin composite hygrothermal environment tensile and compress stren-gth moisture absorption failure mode dynamic mechanical property
