Abstract

A metal honeycomb plate sandwich layer is of a hexagonal honeycomb structure, and is light in weight and strong in load. Although the hexagonal honeycomb can use the least materials to define a maximum effective space, the geometrical shape of the hexagonal honeycomb can be easily changed through an external force of a section axial plane in any direction. When an axial external force is applied on any point on the plane, the hexagonal honeycomb can be easily deformed, which is beneficial to deformation processing of a honeycomb plate, but is not good for achieving the aims of light weight and high strength. In addition, an adhesive can pollute the environment. The invention relates to an orthogonal card core metal honeycomb plate, the honeycomb plate sandwich layer thereof adopts an orthogonal plug-in card structure, the defined space is a regular square prism matrix, a honeycomb core is made of materials 1 / 4 more than that of traditional hexagonal honeycomb sandwich layer, but the orthogonal plug-in card honeycomb sandwich layer structure is compacted into an integral whole, especially the rigidity along a longitudinal and a horizontal direction of a plate strip is good, and the deformation degree is small under the action of the external force, so that the orthogonal card core metal honeycomb plate provided by the invention has an ultrastrong load capacity. The honeycomb plate provided by the invention is formed by adopting rivet with same metal materials to anchor or by welding, is long in service life compared with a bonding process, and cannot pollute the environment.

Description

[0001] 【Technical field】 [0002] The invention relates to a honeycomb sandwich structure board made of all metal materials, in particular to a metal honeycomb board whose sandwich layer is not a traditional regular hexagonal honeycomb structure but an orthogonal grid structure. The invention belongs to the field of lightweight high-strength new materials, and specifically relates to the fields of aluminum alloy honeycomb panels, magnesium alloy honeycomb panels, titanium alloy honeycomb panels and other lightweight high-strength alloys and alloy steel honeycomb panels. [0003] 【Background technique】 [0004] Lightweight and high-strength materials with light weight and high strength have been one of the goals that many industries such as the equipment manufacturing industry have been pursuing for many years. Under the premise that the raw materials are basically unchanged, it is one of the preferred structures to achieve the goal of high strength and light weight. [0005] T...
