摘　　要：依据单层吸波体传输线理论，结合计算机辅助设计选配合适的吸波粉体，以铜镍镀层织物和金属纱线混纺织物为基布，以聚氨酯为基体，制备1．5mm涂层厚度的柔性纺织涂层复合面料。对吸波粉体的电磁特性进行测试和分析，考察分析了2．6～18．0GHz范围内吸波粉体与基体的不同混比及基布对反射损耗的影响及其机制。结果表明，在一定范围内随吸波粉体体积分数的增加，吸波效能提升，频段拓宽，反射损耗曲线的峰值向低频移动。以金属纱线混纺织物为基布的涂层面料的吸波效果优于铜镍镀层织物为基布的涂层面料。The appropriate absorbing powders were selected by taking advantage of the transmission line theory of single layer absorber in combination with computer-aided design （CAD）. A flexible coated composite fabric with a layer depth of 1.5 mm was manufactured with copper-nickel coating fabric （CNCF） and metallic yarn blended composite fabric （MYBF） as substrates, respectively and polyurethane as matrix. The electromagnetic properties of absorbing powders were measured and the effects of absorbing powders with different mixed ratios of the matrix on the reflection loss and absorption mechanism of the coated composite fabric were investigated in frequency range of 2.6 - 18.0 GHz. The results showed that within a certain range, with the increase of absorbing powder volume percent, absorbing performance improved, band broadened, and the peak of reflection loss curve moved to the lower frequency. The absorbing performance of the coating fabric based on MYBF was better than that based on CNCF.
