The aluminum honeycomb sandwich panel structure is one with good sound insulation effect and good use performance, and is formed by respectively using aluminum veneers as a panel clamping plate and a bottom plate clamping plate and clamping a honeycomb aluminum core in the middle, and the aluminum honeycomb sandwich panel is manufactured by using stainless steel veneers instead of the aluminum veneers according to use requirements.
The type and the surface density of the splint material are main factors influencing the sound insulation of the aluminum honeycomb sandwich plate for the high-speed railway motor car floor.
