摘要

摘要: 采用粉末叠层方法和热压工艺制备了还原氧化石墨烯改性碳纤维/聚苯硫醚(RGO-CF/PPS)复合材料，考察了复合材料在室温干态和湿热处理两种条件下的层间剪切性能和微观形貌及RGO对复合材料界面性能的影响。结果表明，室温干态0.1%RGO-CF/PPS的层间剪切强度(ILSS)比CF/PPS的提高了18.4%；湿热处理后RGO-CF/PPS的ILSS发生了下降，且湿热处理RGO-CF/PPS的ILSS强度保持率均低于CF/PPS；复合材料的动态热机械行为结果表明，RGO有助于改善复合材料的界面黏结性能；微观形貌分析表明RGO使复合材料中裂纹更易发生偏转从而提高室温干态复合材料的ILSS。

Abstract: Reduced graphene oxide(RGO) modified carbon fiber/polyphenylene sulfide composites (RGO-CF/PPS) were prepared by powder lamination methodand hot pressing process. Interlaminar shear properties and micromorphology of the RGO-CF/PPS composites at room temperature and hygrothermal environment were investi-gated. Meanwhile, the effect of RGO on the interface performance of the composites was analyzed. Results show that the interlaminar shear strength (ILSS) of the 0.1%RGO-CF/PPS composites in the dry state at room tempera-ture is 18.4% higher than that of the CF/PPS composites. After hygrothermal treatment, the ILSS of the RGO-CF/PPS composites are decreased and the ILSS strength retention rate of the RGO-CF/PPS composites is lower than that of the CF/PPS composites. Dynamic thermomechanical behavior results of the composites show that the RGO is helpful to enhance the interface bonding performance of the RGO-CF/PPS composites. Micromorphology shows that the RGO effectively improves the ILSS of the RGO-CF/PPS composites in the dry state at room temperature.
