| With the development of lightweight, high speed and automation of precision instrument and equipment, the vibration problem is increasingly prominent. Sandwich composite has become a hot spot in the field of aeronautics and astronautics due to high strength, high specific modulus, excellent damping performance, the characteristics of structural and functional integration. The damping mechanism from the matrix of composite, reinforcement and interface is elaborated, then the current popular research on the sandwich structures and the influence on damping performance from the core material, panel, bonding interface and interaction between them are introduced. The researches on damping modification of sandwich composite materials are summarized, finally the research direction on sandwich composite damping is prospected. |
