Abstract

The invention provides a thin slab layer which enhances through a strengthening layer such as carbon fiber or a functional material and is used for formation of a honeycomb structure, a honeycomb structure and its preparation method. According to the honeycomb structure, a strengthening layer of cell wall width is glued at the place where the honeycomb cell walls are glued with each other, so as to achieve the following effects: under the circumstance of not increasing the honeycomb structural cell density, plane compression strength / modulus and in-plane shear strength / modulus of the honeycomb structure are greatly raised, honeycomb structure compression amount during the honeycomb structure forming process is greatly reduced, and process window for honeycomb structure formation is expanded so as to ensure that the appearance of a honeycomb structural product is more accurate; and under the circumstance of not increasing the honeycomb structural cell density, functions of the honeycomb structure are increased: if the strengthening layer is carbon fiber cloth, heat-conducting property of the honeycomb structure is enhanced; and if the strengthening layer is a wave-absorbing material, absorbing property of the honeycomb structure is improved.

Description

technical field [0001] The present invention relates to a thin plate layer for forming a honeycomb structure, a honeycomb structure and a preparation method thereof, in particular to a thin plate layer for forming a honeycomb structure, a honeycomb structure and a honeycomb structure reinforced by a reinforcing layer such as carbon fiber or functional material its preparation method. Background technique [0002] The honeycomb structure is a series of porous solid materials with hexagonal, quadrilateral and other shapes of cells made of metal materials, glass fiber fabrics or composite materials. [0003] So far, the improvement of honeycomb mechanical properties can only be achieved by increasing the density of the honeycomb structure. This method obviously loses the effect of weight reduction. How to improve the mechanical properties and / or Or functional characteristics, is the main problem to be solved by the present invention. Contents of the invention [0004] Embod...
