| 摘 要： | 基于所提出的屈曲排布模型制作了碳纤维屏蔽材料,探讨了辐射源频率、屈曲波幅和行间距对其在微波段电磁波(EMW)屏蔽性能的影响.结果表明,辐射源频率因素影响显著,且屈曲排布碳纤维屏蔽材料在1.4～2.0GHz频段内具有良好的屏蔽效果;屈曲波幅和行间距对屏蔽性能影响显著,屈曲波幅为2 H(H为厚度)和行间距为5mm的试样,在测试范围内屏蔽效果相对最优;碳纤维含量的增加对屏蔽性能的影响并不显著. |

| Abstract: | Based on a carbon filaments buckling waved arrangement model for electromagnetic wave (EMW) shielding materials, the effects of the frequency of radiation source, buckling wave amplitude of carbon filaments and space between the carbon filaments on the shielding property of this model in the microwave range were discussed. The results showed that the effect of frequency factor of radiation source was significant and there existed a better EMW shielding property of the shielding material in which the waved carbon filaments were arranged on the frequency of 1.4~2.0GHz.The effects of the structural parameters, including the amplitude of buckling wave and the space between carbon filaments were significant on EMW shielding, especially for 2H buckling wave amplitude and 5mm space. While there was no obvious change of EMW shielding property with the carbon filaments content. |
