摘　　要：根据电磁波传输线理论,将传统片状结构吸波材料设计为梯度渐变多孔层叠吸波结构,增加雷达波在涂层中的传输距离和损耗;采用轻质超高导电炭黑和短切碳纤维复合吸收剂技术,将电磁波损耗由吸收剂单一作用扩展到结构/功能填料吸波一体化,吸波材料随厚度的不同可实现在2～18GHz的雷达波反射率<-15dB,在26～100GHz的雷达波反射率<-20dB,大幅提高材料的宽频吸波性能,为实现雷达隐身材料的"薄、轻、宽、强"提供了新的技术途径。Accoding to the theory of transmission line of electromagnetic wave,made the traditional absorbing materials with laminated structure to gradient gradual porous lamination absorbing structure,increased the transmission distance and loss of radar in the coating.Use the light superhigh conductive carbon and carbon fibre compound absorbent technology,extending the single effect of absorbent of eletromagnetic loss to absorbing integration with structure or functional pigment.The absorbing materials with different thickness can realize that the radar reflectivity at 2-8GHz is less than-15dB,while the radar reflectivity at 26-100GHz is less than-20dB,which can improve the WB absorbing performance of materials.
