Problems solved by technology

The dimensional accuracy of the formed corrugated sheet material is high, so the width of the formed sheet material is generally within 300mm, while the width of the stretched sheet material is generally 900mm. The process of forming / coating adhesive in the manufacturing process of the forming method is for To ensure dimensional accuracy and reduce the amount of springback after forming thin plate materials, the speed is generally within 3m / min, while the speed of stretching method can reach more than 36m / min, so the forming method is very efficient in manufacturing reinforced aramid paper honeycomb structure Low, and the forming method to manufacture reinforced honeycomb is basically not suitable for difficult-to-form materials such as aramid paper, and the materials used have a narrow range of application. Therefore, it is necessary to provide a new manufacturing method with high manufacturing efficiency and a wide range of material applications. Enables Fabrication of Enhanced Honeycomb Structures

Abstract

The invention provides a thin slab layer for formation of an enhanced honeycomb structure and a preparation method of the honeycomb structure. The thin slab layer for formation of the enhanced honeycomb structure and the preparation method of the honeycomb structure have the following beneficial effects: the problem that an enhanced honeycomb structure can only be manufactured by a forming method but cannot be manufactured by a tension method in the prior art is solved; a thin slab material at cell gluing positions in the forming-mode manufacturing is replaced with a strengthening layer of three cell wall width, and the position of binder line is changed between the thin slab material and the strengthening layer so as to realize tension-mode manufacturing; and materials which are not easy to form, such as aromatic polyamide paper, can be used to make the enhanced honeycomb structure, so as to expand the material application range and reduce manufacturing cost. Strength of the honeycomb structure obtained by the preparation method is similar to strength of a honeycomb structure prepared by a conventional forming method. The preparation method has high manufacturing efficiency.

Description

technical field [0001] The invention belongs to the technical field of honeycomb structure materials, in particular to a thin plate layer for forming a reinforced honeycomb structure and a preparation method of the honeycomb structure. Background technique [0002] The honeycomb structure is a series of hexagonal, quadrilateral and other shapes of porous solid materials made of metal materials, glass fibers or composite materials. The honeycomb structure has excellent properties such as light weight, sound insulation, fire prevention, non-fragile, strong rigidity, and environmental protection. , Widely used in building curtain walls and indoor and outdoor decoration, luxury car and ship interior decoration, high-speed trains, aerospace and aviation, etc. Due to the unique advantages of the honeycomb structure, the honeycomb has been developed in the long run. [0003] With the development of honeycomb technology, there are more and more types of honeycomb. The main constitue...
