夹芯型吸波结构耐老化性能研究
AGING RESISTANCE OF MICROWAVE ABSORBING SANDWICH STRUCTURE
摘要
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.关键词
