Multi-layer honeycomb plate

Abstract

The invention discloses a multi-layer honeycomb plate, and belongs to the technical field of materials. The multi-layer honeycomb plate is formed by overlapping a panel, honeycomb plates and partitioning plates. The corresponding partitioning plate is arranged between every two adjacent layers of the honeycomb plates, the honeycomb plates are formed by connecting multiple honeycomb lattices, the honeycomb lattices are hollow, the sections are in a regular hexagon shape, the plate sections of the honeycomb plates are gaps in a regular hexagon shape, the gaps are connected with one another, and projections of side intersecting points, on the plate section of the adjacent layer, of the regular-hexagon-shaped plate section of any one honeycomb plate fall inside the regular-hexagon-shaped section of the adjacent layer plate. The multi-layer honeycomb plate is formed by overlapping the multiple layers of honeycomb plates and the partitioning plates in a spaced mode, gets closer to a real honeycomb with the multi-layer structure, and has good effects on mechanical properties, sound insulation and thermal insulation.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a multilayer honeycomb panel. Background technique [0002] Honeycomb (honeycomb), as a place for the survival and reproduction of bees, is in the shape of a regular regular hexagonal prism. The open end is a regular hexagon, and the closed end is a hexagonal pyramid composed of three identical rhombuses. At the beginning of the 18th century, the French scholar Malarchi found by measuring the honeycomb: the obtuse angle of these rhombuses is 109 degrees 28 minutes, and the acute angle is 70 degrees 32 minutes. , an answer that is completely consistent with the measured results was obtained. Studies have shown that this angle can achieve the purpose of saving the most materials under the condition of a certain volume. [0003] Honeycomb structure, as a bionic structure, is a kind of porous material. Liu Peisheng gave such a definition in his book: [0004] Continuous solids ...

AI Technical Summary

Problems solved by technology

[0006] At present, most of the research and application of honeycomb structure is single-layer structure, and a small amount will involve the research of double-layer honeycomb structure, but the layout of honeycomb structure is simple, and most of the upper and lower layers are completely overlapped. The structure is just an extra layer of panels between the layers, and its mechanical properties, sound insulation effect, and heat insulation performance are not good.
