摘要
研究了连续碳纤维表面化学镀镍工艺,并利用扫描电子显微镜(SEM),X射线衍射仪(XRD)分析了纤维的微观形貌、镍层成分和镍层结构。测试了镀镍碳纤维和镀镍碳纤维复合材料的导电性能。制备了镀镍纤维为增强材料的抗电磁脉冲复合材料。在场强大于20kV/m的环境下测试了复合材料在频率为1.3,2.8,4.3,9.4GHz处的高功率微波电磁脉冲屏蔽效能。结果表明复合材料的高功率微波电磁脉冲屏蔽效能均大于60dB,其中2.8GHz下出现最大值91dB。
In this paper,carbon fibers were plated with the chemical nickel plating method.The microstructure of the nickel-plated carbon fibers,the nickel layer composition and its structures were studied by the scanning electron microscope,energy dispersive X-ray spectroscopy and X-ray diffraction techniques.The conductivities of the nickel-plated carbon fibers and its composites were tested with broadband resistance voltage instrument.The high power microwave（HPM）shielding effectiveness of the composites were also measured with 1.3GHz,2.8GHz,4.3GHz,9.4GHz at the electric field intensity equal or greater than 20kV/m.The results reveal that the HPM shielding effectiveness of the nickel-plated carbon fiber composites is more than 60dB,and the maximum value is 91dB with 2.8GHz.
