| 摘 要： | 实验研究了二维编织环氧树脂基玻璃纤维复合材料层压板在室温和湿热条件下的冲击后压缩性能。结果表明,该体系复合材料平衡吸湿量平均达到2.2%。吸湿过程中材料性能发生退化,退化程度与试件厚度有关。材料达到平衡吸湿后,室温环境下的冲击能量平均下降19.2%。摄氏70℃,相对湿度85%环境下,冲击后压缩破坏应力平均下降54.3%。

| Abstract: | Compress after impact(CAI) of glass-fiber woven reinforcement epoxy laminates was investigated experimentally at room temperature and hygrothermal environment. The results of experimentation indicated that balanced moisture content of this composites was up to 2.2%, and property degradation which depended on specimen thickness took place during moisture absorption. After composites obtained balanced moisture content, average impacted energy decreased by 19.2%, and average ultimate failure stress of CAI decreased by 54.3% at 70 with 85% relative humidity. |
