摘要:
织物组合方式影响多层织物的屏蔽效能。选取4种具有不同吸收反射性能、不同结构参数的电磁屏蔽材料,采用法兰同轴法测试单层织物的屏蔽效能,再将不同种类面料的织物以不同的叠放顺序两两组合,测试其屏蔽效能; 以单层织物屏蔽效能为基础,分析双层织物屏蔽效能的变化规律,探讨组合方式对多层电磁屏蔽织物屏蔽效能的影响。研究结果表明:在测试频率范围内,相较单层织物,双层织物的屏蔽效能提高了10～40 dB,在2 000～3 000 MHz频段内比30～1 000 MHz频段内提高更多; 吸收型双层织物在30～1 500 MHz范围内的屏蔽效能峰值大于在1 500～2 000 MHz范围的,反射型双层织物则相反,即吸收型双层织物屏蔽效能在高频段增幅小于反射型双层织物; 双层织物屏蔽效能会因为其叠放顺序不同有所变化,外层反射型面料里层吸收型面料的双层组合屏蔽效能最佳。
Abstract:
Fabric combination mode affects the multi-layer fabric shielding effectiveness. This paper selects four electromagnetic shielding materials with different absorption, reflection performance, and different structural parameters. The flange coaxial method was used to first test the single-layer fabric shielding effectiveness, and then different fabrics were combined in pairs based on fabric type and stacking order, and their shielding effectiveness were tested. Then, the variation rules of double-layer fabric shielding effectiveness was analyzed based on the single-layer fabric shielding effectiveness, and the influence of combination way of the shielding effectiveness of multi-layer electromagnetic shielding fabric was explored. The research results show that, in the test frequency range, the shielding efficiency of double-layer fabric is much improved by 30～40 dB,and more better in the range of 2 000 to 3 000 MHz than the range of 30 to 1 000 MHz; the shielding efficiency value of absorption double-bilayer fabric within 30 to 1 500 MHz is greater than 1 500 to 2 000 MHz, that is, the shielding efficiency rate of absorbed double-layer fabric is less than that of reflective double-layer fabric; double-layer fabric shielding effectiveness will be different due to its stacking order, and the combination of the outer layer of reflective fabric and the inner layer of absorbing fabric double-layer shows a best shielding effect.
