| 本文利用非晶铁磁纤维的应力阻抗效应,对基于玻璃包裹非晶铁磁纤维(CoFeNiSiB)的电磁复合材料的吸波性能,采用自由空间透射法进行了一系列实验研究,重点在于探究该电磁复合材料吸波性能的影响因素,特别是外加应力对吸波效果的调谐性研究。实验结果表明,非晶铁磁纤维电磁复合材料的透波率与纤维方向、密度、长度等因素有密切的关系,在电磁复合材料基体刚度较小的情况下,非晶铁磁纤维电磁复合材料的吸波性能具有较明显的应力调谐性。该研究在智能隐身材料、微波无损检测等领域都有着潜在的重大应用价值。 |
| 英文摘要: |
| A series of experimental investigations on electromagnetic dispersion characteristics of glass-coated amorphous ferromagnetic filled composite was performed based on free space transmission method and stress impedance effect of amorphous ferromagnetic fiber. The tested amorphous ferromagnetic fiber filled composite is(CoFeNiSiB)with glass-coated wire inclusions and epoxy resin. The investigation was focused on the factors effecting wave absorbing properties of this composite, especially the effect of acted stress on the adjustability of wave absorbing. Experimental results show that microwave transmission coefficient of the composite depends on fiber length and fiber array, including orientation and density etc. Tentative experiments about adjustable wave absorbing behavior based on amorphous ferromagnetic fiber were also carried out by applied tension stress and taking into account its Stress-Impedance(SI) effect. Stress adjustable behavior of the composite was demonstrated and interpreted. Above results can be used for microwave non-destructive testing and smart stealth technilogy. |
