摘要
碳纤维复合材料的屏蔽效能对系统抗电磁脉冲设计具有重要影响。本文通过理论分析建立了碳纤维复合材料的屏蔽效能模型,研究了频率、厚度等因素对碳纤维复合材料屏蔽效能的影响。结果表明,碳纤维复合材料具有较为良好的屏蔽效能,屏蔽效能在频率拐点以下随频率变化较小,在频率拐点以上随频率增大迅速增大,并通过了试验验证。
Carbon fiber composite matbrial is gaining wider use in aerospace systems. Its shielding effectiveness is limited due to the conductivity. The shielding effectiveness is theoretically modeled and its result is verified by ex- periments. The influence of frequency, thickness is analyzed on the basis of the model.
