A two-layer plate frame type vibration damping base of a composite structure comprises an equipment installation rigid base, an upper layer composite material plate frame, a middle layer rigid vibration-isolation panel, a lower layer composite material plate frame and a rigid connection transition plate which are sequentially distributed from top to bottom in the vertical direction. The upper end and the lower end of the upper layer composite material plate frame are fixedly connected with the equipment installation rigid base and the middle layer rigid vibration-isolation panel respectively, and the upper end and the lower end of the lower layer composite material plate frame are fixedly connected with the middle layer rigid vibration-isolation panel and the rigid connection transition plate respectively. By means of the two layers of composite material plate frames, a hard-soft-hard-soft-hard elastic vibration-isolation structure is integrally formed, characteristics of a composite material can be fully used, the dual aims of reducing vibration and noise and reducing the weight of the base are achieved on the premise that the rigidity and strength requirements of the vibration damping base structure are met, and low-frequency noise reduction can be achieved.
