摘要：
A multi-layered electromagnetic absorbing composite was proposed to have the structure composed alternately of absorbing prepreg layer and absorbing damping layer, thus the embedded cocuring composite with excellent electromagnetic absorbing property and high damping property as well as other excellent static and dynamic properties was developed. The theoretical expression of the electromagnetic reflection loss of the structure was deduced, and the absorbing performance of the structure was theoretically analyzed by using MATLAB program based on the theoretical expression. The electromagnetic absorbing test verified the validity of the theoretical results. Modal test, free decay test and interlinear shear test obtained the variation curve of modal parameters, damping performance and interlamellar shear performance with the content of electromagnetic absorbing material. The experimental data show that with the increase of the content of electromagnetic absorbing materials in the composite, of which the reflection loss and the modal natural frequency decrease, the electromagnetic absorption bandwidth, the modal damping ratio and the damping loss factor increase, whereas, the interlamellar shear stress enhances. © All right reserved.
