碳纤维增强聚合物基复合材料频率选择表面的电磁传输特性
Electromagnetic transmission characteristics of frequency selective surfaces with carbon fiber fabric/epoxy composite
摘要
Abstract
There are problems,such as thermal residual stress and second bonding layers,in radome which is prepared by metal FSSs (frequency selective surfaces).To avoid these disadvantages,carbon fiber fabric /epoxy composite which has good compatibility with radome wall structure of polymer composite was adopted to prepare FSSs;the free space method was carried out to evaluate the electromagnetic transmission characteristics of the composite FSS specimens;the numerical analysis model was employed to analyze the electromagnetic transmission mechanism and influencing factors of FSS.Results show that:the composite FSS with carbon fiber can realize the function of frequency selection,while the transmission loss at the position of resonance frequency is great;the electromagnetic transmission performance of composite FSS can be adjusted by changing the aperture-to-cell ratio,thickness,conductivity and dielectric constant.关键词
