摘要: 在纤维增强树脂基复合材料中添加代号分别为S-5,S-1A,HT,XF-4b,SM,TX,XF-2微米级颗粒吸收剂,在保证良好隐身性能的前提下,赋予了材料一定的力学性能。对应于10 dB隐身水平,平板试样的有效吸收频带宽度大约在10 GHz。非标准试样的动态力学性能测试结果表明:本结构型隐身材料具有良好的抗冲击性能,然而,标准试样的静态拉、压、弯、剪等指标低于传统结构材料。

Abstract: By adding several micro-step absorbing particles, a satisfactory absorbing property can be obtained. According to the absorbing level of 10 dB, the effective absorbing band of a plane-boarded specimen is about 10 GHz. The test of the dynamic mechanical property of non-standard specimens shows that this kind of structural absorbing composite has a higher resist-impact property; however, the stationary mechanical property of standard specimens is low compared with traditional material.
