Abstract

The invention discloses an aviation plywood, which comprises: a bottom plate, which can be bent to form an accommodating space; a plate core, which is arranged in the accommodating space in a filling manner, and is connected with the bottom plate through an adhesive; a panel, which is bent to cover the bottom plate, so that the accommodating space forms a closed space, and the panel is connected with the plate core and the bottom plate through an adhesive; wherein surface structures are formed on the surfaces of the bottom plate, the plate core and the panel, and lines of the surface structures of the mutual contact surfaces of the bottom plate, the plate core and the panel are arranged in a crossed manner; the adhesive comprises high-density polyethylene and low-density polyethylene. The aviation plywood has good strength and water resistance.

Description

technical field [0001] The present application relates to the field of panels, in particular to an aviation plywood. Background technique [0002] Plywood is formed by laminating multiple layers of plate-like materials, usually glued together by glue, and plywood is used in aviation manufacturing. Currently, the strength of plywood on the market is low, and it will deform or even break when subjected to a large force In addition, when the plywood is in a humid environment, moisture will enter the interior of the plywood and degumming will occur, resulting in cracking and delamination of the plywood, reducing its strength. Contents of the invention [0003] The technical problem mainly solved by this application is to provide an aviation plywood to solve the problem of insufficient strength and poor water resistance of the plywood in the prior art. [0004] In order to solve the above technical problems, a technical solution adopted by the present application is to provide...
