초록
In this paper, the composite damping sheet with electromagnetic wave absorption was developed and studied. The damping sheets with Ni-Zn ferrite, Mn-Zn ferrite and PZT were prepared by mixing, molding and drying. From the characterizing results, the optimal portion of the composite is 1:1:0.1 of Mn-Zn ferrite:Rubber:PZT. The maximum absorption was -30 dB at 860 MHz in the single structure and over -15 dB at 180 MHz and 860 MHz in the two or three layers.
