Background

Researchers have found that hexagonal cells made by bees can be constructed into extremely firm honeycombs with minimal material consumption, and the arrangement of multiple wall surfaces and a series of continuous honeycomb-shaped net structures can disperse external forces from all parties, so that the resistance of the honeycomb structure to extrusion force is much higher than that of any original shape or square shape. Therefore, the honeycomb sandwich structure is a light structure and has high specific strength and specific rigidity. The honeycomb plate is made according to the honeycomb principle, and is a plate made by firmly bonding two thin panels on two surfaces of a layer of thicker honeycomb core material, and is also called as a honeycomb sandwich structure. In addition, the honeycomb panel also refers to a panel in which a large number of cut waveguides are welded together to form a cut waveguide array, thereby forming a large opening area and preventing electromagnetic wave leakage

However, the common honeycomb plate not only occupies a large volume and has low space utilization rate due to large honeycomb cavity, but also easily generates radiation heat transfer and local convection heat transfer, limits the heat insulation and preservation effect and has insufficient functionality. With the development of energy-saving buildings and the improvement of environmental protection consciousness of people, the heat insulation effect of the honeycomb plate still has a large space, and the existing honeycomb plate lacks the effects of water resistance, fire resistance, shock absorption and the like, so that the function of the honeycomb plate needs to be improved.
