摘要：
A new type of five-layer sandwich composite panels was presented in detail. The upper and lower skins and center layer were designed as embedded co-cured composite structures with multilayer damping films. Between the upper skin and center layer as well as between the lower skin and the center layer, a layer of polymethacrylimide foam material with a certain thickness was put in. The dynamic performances of the specimen were analysed deeply by using the finite element simulation and experimental modal analysis. By making comparison between the relative results, the conclusion shows that the designed structure has very high damping and specific stiffness characteristics, and will provide a foundation to the design principle and application of light-weight, large-damping and high-precision composite materials instrument panels. © 2017, Editorial Office of Journal of Vibration and Shock.
