摘要
在碳纤维织物表面接枝氧化石墨烯(GO)及经硅烷偶联剂(KH550)处理的氧化石墨烯(KHGO),采用真空辅助树脂传递模塑工艺(VARTM),制备碳纤维织物/环氧树脂复合材料,测试碳纤维织物改性前后的力学性能。结果表明KHGO改性能使碳纤维织物增强复合材料的弯曲强度和层间剪切强度分别提升9.9%和18.6%。
Graphene oxide(GO)and graphene oxide(KHGO)treated with silane coupling agent(KH550)were grafted on the surface of carbon fiber fabric.Carbon fiber/epoxy resin composites were prepared by vacuum assisted resin transfer molding(VARTM)process.The mechanical properties of carbon fiber fabric before and after modification were tested.The results showed that the bending strength and interlaminar shear strength of carbon fiber fabric reinforced composites modified with KH550GO were increased by 9.9%and 18.6%,respectively.
