Abstract In this work, carbon fabric-reinforced epoxy (CF/EP) composites reinforced by graphene oxide-coated short glass fibers (GO/SGF) were manufactured and characterized. The interlaminar shear strength (ILSS) of CF/EP composites at room temperature (RT) and cryogenic temperature (77K) was compared, and the enhancement mechanism was revealed through the analysis of microstructure. The result shows that bonding via hydrogen bonding with GO improved the compatibility of the SGF in the epoxy matrix. The ILSS of the composite reached the maximum value at the content of 0.4wt% GO/SGF, and increased by 24.3% and 21.3% at RT and 77K, respectively. The improvement on the interlaminar shear performance is attributed to the bearing of transverse shear force by the SGF between the composite layers.

氧化石墨烯包覆玻璃纤维改善碳纤维/环氧树脂复合材料低温层间剪切性能研究

摘要 在这项工作中，制备并表征了由氧化石墨烯涂覆的短玻璃纤维 (GO/SGF) 增强的碳纤维织物增强环氧树脂 (CF/EP) 复合材料。比较了CF/EP复合材料在室温（RT）和低温（77K）下的层间剪切强度（ILSS），并通过微观结构分析揭示了增强机制。结果表明，通过氢键与 GO 键合提高了 SGF 在环氧树脂基体中的相容性。复合材料的 ILSS 在 0.4wt% GO/SGF 含量下达到最大值，在 RT 和 77K 时分别增加了 24.3% 和 21.3%。层间剪切性能的提高归因于复合层之间的 SGF 承受横向剪切力。
