| 摘 要： | 分别研究了平铺排布的碳毡和单向排布的碳纤维类吸波复合材料的微波吸收特性。结果表明:单向排布的聚丙烯腈基碳纤维的吸波性能与纤维的排布间距和纤维含量密切相关。本实验条件下可获得有效带宽大于3 GHz,10 dB以下的反射衰减。平铺排布碳毡的吸波性能随碳毡含量的影响较大,含量0.27 wt%时,在8 GHz~18 GHz 频段获得90 %以上的吸收率。

| Abstract: | Microwave absorbing properties of carbon fiber felt and parallel-arranged carbon fiber composites were investigated respectively. The results show that the absorbing properties of parallel-arranged composites were affected greatly by the distance and content of carbon fibers. In this research, the composites obtained a reflection loss above 10 dB over 3 GHz bandwidth. The carbon fiber felt materials exhibited promising characteristics of absorption over the frequency range of 8 GHz~18 GHz with 0.27 wt% felt. The properties were affected mainly by the content of felt. |
