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.

隨著信息化技術(shù)的快速發(fā)展以及對醫(yī)療系統(tǒng)成本控制要求的提高，尤其是當成本控制參與到醫(yī)院的決策過程中時，醫(yī)院器械的整體質(zhì)量和服役性能將決定醫(yī)院的決策效率和服務(wù)質(zhì)量，這就對醫(yī)院器械（直接或者間接用于人體的儀器、設(shè)備、器具等）的各項性能提出了更高的使用需求，如纖維復合材料醫(yī)療器械除需要滿足傳統(tǒng)材料已有的物理和化學性能外，還需要具有良好的電磁屏蔽性能和熱穩(wěn)定性等。（剩余5159字）
