摘要

摘要: 为了提高碳纤维增强环氧树脂（CF/EP）复合材料在低温（77 K）循环条件下的抗微裂纹性能，采用共沉淀法制备了具有良好顺磁性的Fe₃O₄修饰氧化碳纳米管（Fe₃O₄-O—MWCNTs），并研究了Fe₃O₄-O—MWCNTs在环氧树脂（EP）基体中的有序排列对EP及CF/EP复合材料低温性能的影响。结果表明：Fe₃O₄-O—MWCNTs的有序排列可有效提高EP基体的低温力学性能及降低EP基体的热膨胀系数，相对于纯EP，Fe₃O₄-O—MWCNTs改性EP的热膨胀系数降低了41.6%；相对于CF/EP复合材料，Fe₃O₄-O—MWCNTs改性CF/EP复合材料在低温环境下的微裂纹密度降低了56.2%。

Abstract: In order to improve the micro-cracks resistance of carbon fiber reinforced epoxy (CF/EP) at cryogenic temperature (77 K), Fe₃O₄ modified O-MWCNTs (Fe₃O₄-O-MWCNTs) with good paramagnetic properties were prepared by co-precipitation method. The effects of the addtions of aligned Fe₃O₄-O-MWCNTs on the properties of epoxy (EP) and CF/EP composites at 77 K were studied. The results show that the aligned Fe₃O₄-O-MWCNTs can effectively improve the mechanical properties of EP matrix at 77 K and reduce the coefficient of thermal expansion (α) of EP matrix. It can also obviously improve the micro-crack resistance of CF/EP composites at 77 K. Comparing to the neat EP, α of aligned Fe₃O₄-O-MWCNTs modified EP composite decreases by 41.6%. Comparing to CF/EP composite, the micro-crack density of aligned Fe₃O₄-O-MWCNTs modified CF/EP composite at 77 K decreases by 56.2%.
