理想的隐身雷达罩通常是由E玻璃/环氧复合材料、聚氯乙烯泡沫和频率选择表面(FSS)组成的夹层结构。尼龙6/6和巴尔萨木材以其低介电性能而闻名。在这项工作中，现有隐身雷达罩的电磁波传输特性通过使用尼龙6/6纤维和巴尔萨木材以及E-玻璃纤维/环氧复合材料在不影响力学性能的情况下得到改善。利用自由空间测量技术测量了特定频率段(8.2-12.4 GHz)内的电磁波传输特性。通过三点弯曲试验研究了夹层结构的抗弯强度。
The ideally invisible stealth radomes are usually sandwiched constructions composed of E-glass/epoxy composite, polyvinyl chloride foam and frequency selective surfaces (FSS). Nylon 6/6 and balsa wood are well known for their low dielectric properties. In this work the electromagnetic (EM) wave transmission characteristics of the existing stealth radomes were improved by employing nylon 6/6 fibre and balsa wood, along with E-glass/epoxy composite without compromising the mechanical properties. The free space measurement technique was performed to measure the EM wave transmission characteristics in the X-band frequency range (8.2–12.4 GHz) for a specific FSS. The flexural strength of the sandwiched constructions were investigated with three-point bending test.
