Problems solved by technology

This material has the following problems in production and use: one, because the manufacture of this material needs to be formed by inserting and cross-linking each other with many wedges with uniform distribution and high precision requirements, so producing this material is very difficult. with great difficulty
Second, because this paper-based material uses many parallel and equidistant wedges, it can only arrange the triangular cavity in one direction, and the angle of the triangle cannot be changed according to the object of use to adjust the angle of resisting external force. Therefore, the improvement of strength and stiffness is also limited.
[0004] The 99120077 patent application provides a triangular cavity structure composite material, but because the contact between the folded plate and the lining plate is almost a line contact, the bonding force between the two is affected, and the production is difficult, so it is not very suitable for some occasions

Embodiment Construction

[0023] The material of the present invention comprises at least one layer of trapezoidal cavity shell layers arranged side by side and complementarily arranged, and the embodiment using paper as raw material is now described:

[0024] First process a folded middle layer 1, that is, press creases on a cardboard according to the design parameters such as the width of the upper bottom and the height of the trapezoid. , The lower lining layer 2 is bonded and fixed to form. The middle layer 1 also can adopt paper sheet to be made into the shape as shown in Figure 1 on special equipment. During the bonding process, the joint surface of the folded plate and the lining plate is pressed at a certain distance to fit the fitting marks 4 . Simultaneously soak with adhesive curing agent. The adhesive curing agent can be epoxy resin, which can be cured by various organic and inorganic adhesives, such as urea-formaldehyde resin, unsaturated resin, cement, gypsum, etc. It can also be prepa...

Abstract

The present invention relates to a kind of trapezoidal cavity structure material, including lots of trapezoidal cavity tube bodies. Said material at least has a layer of side-by-side complementary arranged trapezoidal cavity tube body layer. The side-by-side arranged trapezoidal cavity tube body layer includes a zigzag intermediate layer and a lining layer adhered with trapezoidal bottom of two sides of zigzag intermediate layer. When structure includes at least two layers of side-by-side arranged trapezoidal cavity tube body layer, the adjacent trapezoidal cavity tube body layers are mutually adhered together by means of shared lining layer, and the arrangement of adjacent two layers of trapezoidal cavity tube body layers is parallelly-arranged, also can be vertically-arranged. The zigzag intemediate layer and lining layer material is made up by using paper through the processes of adhesion and hardening treatment by hardening agent, so it possesses extensive application.

Description

field of invention [0001] The present invention relates to a material with a trapezoidal cavity structure. Specifically, the trapezoidal cavity structure is used to increase the duty ratio, reduce the self-weight of the material, obtain higher specific strength and specific stiffness, and obtain heat insulation performance A trapezoidal cavity structure material. technical background [0002] Before the present invention was proposed, a composite material was disclosed in the prior art. Its structure is that a wave-shaped interlayer is bonded between two layers of plate materials. This material is mostly used for packaging materials, mainly for shock absorption and resistance. The effect of external impact. The main structure used to resist external forces is the corrugated interlayer. However, this wave-shaped interlayer is only effective for small impact loads, and under a large load, the wave-shaped interlayer will collapse and lose the ability t...
