Research on the WB absorbing materials with porous lamination

LIU Xiao-hui,ZHOU Xue-mei,ZHOU Guang-hua,WEI Wen-zheng(No.59Institute of China Ordnance Industry,Chongqing 400039,China)  
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.
