Performance evolution of carbon fiber composites under moisture absorption coupled four-point bending load

  • 摘要: 为研究吸湿耦合四点弯曲载荷条件下碳纤维增强环氧树脂基复合材料的性能演变规律,通过自行设计的夹具施加四点弯曲载荷,并耦合5倍浓度模拟海水吸湿环境以模拟复合材料承载结构在海水中的服役条件。通过裂纹观测系统原位监测复合材料在力学实验过程中的损伤萌生与扩展,对比分析不同预处理条件对复合材料剩余力学性能及损伤模式的影响,分别通过四点弯曲、三点弯曲及短梁剪切力学试验,对预处理中复合材料的加载区域、等弯矩段进行评估。结果表明,预处理后复合材料的四点弯曲性能降低,一端加载处出现损伤破坏后,随之继续发生多次载荷下降直至最终失效发生;复合材料的等弯矩段短梁剪切性能无明显变化,三点弯曲力学试验结果表明预处理条件对等弯矩段的应力集中作用不显著。从而,预处理条件对加载区域影响显著,使其在失效过程中呈现出多断口扩展,伴随有层间裂纹扩展现象,而对等弯矩段无显著影响。
