摘要/Abstract

摘要： 选取紫外辐照、湿热及盐雾等典型海洋环境因素,对设计的夹芯型吸波结构开展加速老化实验,对比考核夹芯型吸波结构与吸波贴片的耐老化性能。结果表明:紫外老化15 d后,夹芯型吸波结构面层Q-GFRP的介电常数降幅最大,导致其有效带宽向高频方向削减达0.41 GHz;盐雾老化30 d后,吸波贴片的氧化锈蚀最严重,致使其吸收峰值和有效带宽较老化前分别下降达-6.59 dB,削减达2.40 GHz;得益于Q-GFRP的保护,夹芯型吸波结构的耐老化性能明显优于吸波贴片,且经加速老化处理后,仍可满足水面舰艇在X波段、Ku波段的雷达隐身需求。

Abstract: In this study, the accelerated aging test of microwave absorbing sandwich structures is carried out, under the typical marine environmental factors such as wet hot and salt fog. The aging resistance of microwave absorbing sandwich structure and absorbing patch is also compared. Several conclusions have been drawn at last after ultraviolet aging for 15 days. The decline of Q-GFRP′s dielectric constant is most obvious, which lead to the effective bandwidth of microwave absorbing sandwich structure being reduced by 0.41 GHz. Salt-fog aging 30 days later, the oxide rust of microwave absorbing patch is most serious. At the same time, the absorption peak and effective bandwidth are reduced by -6.59 dB and 2.40 GHz, respectively. Besides, due to the protection of Q-GFRP, the aging resistance of microwave absorbing sandwich structure is superior to absorbing patch. And, after accelerated aging treatment, it can still meet the radar stealth requirements of warship in X-band and Ku-band.

Key words: microwave absorbing sandwich structure, microwave absorbing patch, accelerated aging test, aging resistance, radar stealth
