Abstract:
本文以片状羰基铁吸收剂作为硅橡胶基吸波材料的主吸收剂，通过混炼分散、模压硫化的方式制备出硅橡胶基吸波材料，并对制备的硅橡胶基吸波材料的电磁参数和雷达波反射率进行了表征。通过对电磁参数和雷达波反射率的实验结果分析可以发现：通过模压的方式制备的橡胶基吸波材料具备介电损耗和磁损耗双复型损耗特性，通过对橡胶基吸波材料的雷达波反射率的仿真模拟可以发现，基于片状羰基铁粉体的橡胶基吸波材料的低频雷达波反射率吸波效果较好。本文同时对双复损耗型吸波材料的雷达波吸收机理进行了分析。
In this paper flake carbonyl iron absorbent was used as the main absorbent of silicone rubber-based microwave absorbing material to prepare silicone rubber-based microwave absorbing material by mixing dispersion and molding vulcanization. The electromagnetic parameters and radar reflectivity of the prepared silicone rubber-based microwave absorbing material were characterized. Through the analysis of the experimental results of electromagnetic parameters and radar wave reflectivity, it can be found that the rubber-based absorbing material prepared by molding has the characteristics of dielectric loss and magnetic loss dual complex loss. Through the simulation of the radar wave reflectivity of the rubber-based absorbing material, it can be found that the rubber-based absorbing material based on the flake carbonyl iron powder has better low-frequency radar wave reflectivity and absorption effect. At the same time, the radar wave absorption mechanism of the dual-complex loss absorbing material is analyzed.
