摘要

以Si、Al

、MoSi

微粉和生物竹材为原料，采用包埋烧结法分别制备出SiC多孔材料、Al

/SiC、MoSi

/SiC复合材料。采用XRD、SEM及波导法测试其物相组成、显微结构及吸波性能。结果表明：MoSi

/SiC复合材料的厚度为2 mm时有明显的吸波特性，有效吸收带宽在X波段的9.65~12.4 GHz频率范围内达2.75 GHz，且最低反射损耗为-38.27 dB。Al

/SiC复合材料孔道内的Al

与SiC晶须交缠，形成大量电偶极矩，产生介电损耗；MoSi

/SiC复合材料除介电损耗外还存在电阻损耗，使得复合材料电磁损耗增加，是较有前途的结构功能吸波材料。

Abstract

MoSi

powder and biological bamboo were used to produce SiC porous ceramic

/SiC and MoSi

/SiC porous composites by embedding and sintering method. The phase composition

microstructure and absorbing performance of the composites were measured by XRD

SEM and waveguide method

respectively. The results show that the MoSi

/SiC composite has obvious absorbing performance when the thickness is 2 mm. The effective absorption bandwidth is 2.75 GHz in the frequency range of 9.65—12.4 GHz in the X-band

and the minimum reflection loss is -38.27 dB. There are many SiC whiskers intermingled with Al

in the pores of Al

/SiC composites

and a large number of electric dipole moments

generated dielectric loss. In addition to dielectric loss

MoSi

/SiC composites also have resistive losses

and the sponge structure of the metal Mo

4.8

0.6

and MoSi

connecting rod formed in the tunnel constitutes a small conductive network to generate leakage loss to consume electromagnetic waves

so that the electromagnetic loss of the composite increases. So it will be more popular structural functional microwave absorbing materials in the future.
