Abstract：Basedon the demand for electromagnetic shielding performance and thermal stability offiber composites in hospital equipment under the background of cost control，the efects of graphenecontent on the microstructure， microstructure and properties offibercomposites were investigated by adding graphene with diferent content to fiber composites.The results showed that the addition of graphene improved the interfacial adhesion between the carbon fiberand 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 compositescould help improve the thermal stabilityof composites.Under the same electromagnetic frequency，the total eficiency of fibercomposites fromhigh to low was： G0.49，GO.78，GO.34，GO.15，GO，and when the graphene content was 0.49% ，the composite materials had the highest total eficiencyandthebestelectromagneticshieldingability，which issuitableforapplicationinhospitalequipment composites under the background of cost control.
