Built-in type weft-direction reinforced metal honeycomb structure and manufacturing method thereof

Abstract

The invention relates to a built-in type weft-direction reinforced metal honeycomb structure and a manufacturing method thereof. The built-in type weft-direction reinforced metal honeycomb structure comprises a honeycomb core. The honeycomb core is provided with multiple parallel trapezoidal strips. Each trapezoidal strip is provided with at least two unit sections which are sequentially connectedin an end-to-end manner. Each unit section is composed of a first base plate, a first waist plate, a second base plate and a second waist plate which are sequentially connected in an integrated manner, wherein the first waist plate and the second waist plate are symmetrically distributed at the two ends of the second base plate. The first base plate and the second base plate of every two adjacenttrapezoid strips are fixedly connected, and the honeycomb core with multiple unit cells is formed. The built-in type weft-direction reinforced metal honeycomb structure further comprises built-in plates. The built-in plates extend in the weft direction and is perpendicular to the width direction of the trapezoidal strips and embedded into the unit cells which are sequentially distributed in the weft direction. The base plates corresponding to the unit cells which are sequentially distributed in the weft direction are fixedly connected with the built-in plates. The honeycomb structure is highin strength in all directions.

Description

technical field [0001] The invention relates to an embedded latitudinal reinforced metal honeycomb structure and a manufacturing method thereof, belonging to the field of composite plates / profiles. Background technique [0002] The honeycomb structure is the result of natural evolution, and its practical significance is to use the least material to obtain the strongest structure. This feature meets the demand for lightweight materials in the engineering field. Today, the artificial honeycomb structure with honeycomb panels as the main development direction has made great progress. In addition to light weight and high strength, this structure also has many excellent properties such as energy absorption, shock absorption, sound insulation, and heat insulation. [0003] Chinese patent specification CN102774042A discloses a honeycomb reinforced plate and its manufacturing method. The manufacturing method of the honeycomb core material is as follows: first cut the metal plate in...

AI Technical Summary

Problems solved by technology

In the brazing of the honeycomb core and the metal plate, the contact area between the two is less than 10% (generally 3-8%), that is to say, even if 100% of the contact area can be welded (the brazing difficulty of the honeycomb plate is much greater than Conventional plate), the welding area between the metal plate and the honeycomb core is also less than 10%, so the connection strength between the honeycomb core and the metal plate is difficult to reach a very high level, only 10% or less of the brazing strength of the usual plate
