| 摘要: |
| 介绍了阻抗匹配设计原理。自制了三种导电纤维，分别织成正交平纹布，通过优化设计，采用简单层式结构，以酚醛为基体，制备出接近实用水平的多层结构吸波材料。该材料厚3.2mm，密度1.38g/cm3，面密度4.42kg/m2；在8.4GHz～18GHz反射率小于-10dB；弯曲强度173MPa，弯曲模量12.5GPa。 |

| Abstract: |
| The impedance matching design is briefly introduced. Three kinds of conductive fibers were prepared. Then the fibers were woven into tabby fabrics. A new kind of multilayer structural radar absorbing material was made with these conductive tabby fabrics. From 8.4GHz to 18GHz, the reflection attenuation of the material exceeds 10dB. The material is light (3.2mm thick and density 1.38g/cm3) and of good mechanical properties (flexural strength 173MPa，toughness 12.53GPa). |
