Sandwich structure of extra light dot matrix material

The invention discloses a sandwich structure of an extra light dot matrix material, and belongs to the technical field of material research. The sandwich structure of the extra light dot matrix material is composed of single cell element in a replication manner. The cell element is composed of seven square planes and comprises a top surface, four sides, a bottom connected with two adjacent sides and an underside at the side being opposite to the top surface. The cell element can form a sandwich structure in X direction and Y direction of a right angle coordinate system after duplicated for many times, the top and the bottom are pasted by the same material panel and the extra light dot matrix material can be achieved. The sandwich structure of the extra light dot matrix material is composed of the panels by punching and combining mode, is simple in form, easy to manufacture, stable in performance and applied to industry equipment technology, aviation technology and civil engineering industry and the like.
