In order to meet the requirements of “wide, thin, strong and light” for military stealth materials, it is of great practical value to study the absorbing characteristics of multi-layer MWCNTs/Fe3O4/NBR absorbing materials in space. First, we use the large-scale software COMSOL Multiphysics to simulate the absorbing characteristics of the composite thin plate in space. Then the four-port network matrix is used to calculate the absorbing characteristics of the composite plate in space. Finally, the Free-Space method is used to measure the reflection attenuation loss, and the results of the three methods are compared and analyzed. The results show that when the frequency is 10 GHz, the reflection loss of multi-layer MWCNTs/Fe3O4/NBR reaches the maximum value of −27.91, −27.01 and −22.56 dB by COMOSL numerical simulation, four-port network the matrix and Free-Space experimental measurement. The results of the three methods show that the reflection loss is less than −10 dB in the frequency band of 6–14 GHz.

多层MWCNTs/Fe3O4/NBR复合材料的空间吸收研究

为满足军用隐身材料“宽、薄、强、轻”的要求,研究多层MWCNTs/Fe 3 O 4 /NBR吸波材料在太空中的吸波特性具有重要的实用价值。首先,我们使用大型软件 COMSOL Multiphysics 来模拟复合材料薄板在空间中的吸波特性。然后利用四端口网络矩阵计算复合板在空间中的吸波特性。最后采用自由空间法测量反射衰减损耗,并对三种方法的结果进行了对比分析。结果表明,当频率为10 GHz时,多层MWCNTs/Fe 3 O 4的反射损耗通过COMOSL数值模拟、四端口网络矩阵和自由空间实验测量,/NBR达到最大值-27.91、-27.01和-22.56 dB。三种方法的结果表明,反射损耗在 6-14 GHz 频段内小于 -10 dB。
