摘　　要：基于成本控制背景下医院器械对纤维复合材料电磁屏蔽性能和热稳定性的需求,通过在纤维复合材料中加入不同含量石墨烯的方法,考察了石墨烯含量对纤维复合材料显微组织、微观结构和性能的影响。结果表明,石墨烯的加入改善了碳纤维与树脂基体的界面结合力,在承受相同外加载荷时,碳纤维不会出现大量拔出现象。在纤维复合材料中添加石墨烯有助于提升复合材料的热稳定性。在相同电磁频率下,纤维复合材料的总效能从高至低顺序为:G0.49、G0.78、G0.34、G0.15、G0,石墨烯含量为0.49%时复合材料具有最高的总效能和最佳的电磁屏蔽能力,适于在成本控制背景下医院器械复合材料中应用。Based on the demand for electromagnetic shielding performance and thermal stability of fiber composites in hospital equipment under the background of cost control,the effects of graphene content on the microstructure,microstructure and properties of fiber composites were investigated by adding graphene with different content to fiber composites.The results showed that the addition of graphene improved the interfacial adhesion between the carbon fiber and the resin matrix,and the carbon fiber would not be pulled out in large quantities when subjected to the same applied load.The addition of graphene to fiber composites could help improve the thermal stability of composites.Under the same electromagnetic frequency,the total efficiency of fiber composites from high to low was:G0.49,G0.78,G0.34,G0.15,G0,and when the graphene content was 0.49%,the composite materials had the highest total efficiency and the best electromagnetic shielding ability,which is suitable for application in hospital equipment composites under the background of cost control.
