摘要
单层吸波涂料一般吸波频带较窄,而多层吸波涂料吸波频带较宽。本研究采用三层结构设计,有效展宽吸收频带,在吸收频率为6～18GHz范围内,材料的反射率不大于-10dB,材料厚度为2.15mm,面密度4.5kg/m2,多层吸波涂料经过相应的环境试验后仍然能够保持较好的性能。
Single-absorbing coating generally absorbing a narrow band,and multi-layer absorbing a wide-band radar absorbing paint. Three-tier structure design,broadening the effective absorption band in the absorption frequency of 6~18GHz,the reflectivity of the material is not greater than-10dB,the thickness of the material for 2.15mm,density 4.5kg/m2.Multi-layer absorbing coating,after experienced through a series of environmental tests,still have good performances.
