摘要/Abstract

摘要： 利用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了测试和分析，考察分析了2.6GHz-18GHz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理。结果表明在一定范围内吸波粉体体积百分数的增加，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。

Abstract: 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). The flexible textile coating fabrics based on copper-nickel coating fabric (CNCF) and metallic yarn blended composite fabric (MYBF) with polyurethane as matrix were prepared, and the thickness of coatings was 1.5mm. The electromagnetic properties of absorbing powder were measured and analyzed. The effects of absorbing powder and matrix of different mixed ratio and fundamental fabrics on reflection loss and absorption mechanism were investigated and studied in frequency range of 2.6GHz-18GHz.The results showed within a certain range absorbing powder volume percent increase, absorbing performance improved, band broadened, the peak of reflection loss curve moved to lower frequency. The absorbing performance of coating fabric based on MYBF was better than that based on CNCF.

Key words: acetylene carbon black, carbonyl iron powder, substrate, coating, absorbing capacity
