Problems solved by technology

[0003] The strength of the honeycomb sandwich panel mainly depends on the material properties and structural properties of the honeycomb core layer. The traditional honeycomb is prone to instability due to thin-walled cells, resulting in low compressive strength and shear strength, usually less than 0.2MPa, and cannot be used as an industrial product. The use of load-bearing members
However, the new reinforced edge-reinforced honeycomb panel invented by the applicant before can reach the compressive strength of 0.5-0.7MPa (patent application number: 2017102577784: Honeycomb core panel with improved hexagonal structure and its forming method, 2017102581614: Hexagonal structure honeycomb core board and its forming method), but after the cells are stretched, adhesion and stretching distortion occur, the cells are seriously deformed, and the stress is unbalanced.

Embodiment 1

[0057] Figure 1 to Figure 6 It shows the first embodiment of the rib interlaced honeycomb core plate of the present invention (glue on one side), the core plate includes at least two original base bands 1, and a reinforcing band 2 is arranged between each original base band 1, Adjacent primordium strips 1 and reinforcing strips 2 are bonded at even intervals, and are pulled apart to form a honeycomb structure with a plurality of hexagonal unit holes 3. Each hexagonal unit hole 3 has a reinforced The S-shaped reinforcing ribs 4 formed by the belt 2, and the S-shaped reinforcing ribs 4 formed on the adjacent reinforcing belts 2 are arranged in a staggered manner with opposite twisting directions. In this structure, a honeycomb structure with a plurality of hexagonal unit holes 3 is formed between each primordium strip 1. Compared with traditional corrugated cardboard, wood, foam plastic and other materials, it has sound absorption and heat insulation, and the process is simple....

Embodiment 2

[0086] Such as Figure 8 to Figure 9 As shown, in the second embodiment of the present invention (double-sided glue coating), the two sides of each second bonding edge 21 are provided with a second bonding area 211, and each second bonding The area 211 extends to the second forming edge 22 in the same direction adjacent to it, and the second bonding area 211 on the adjacent two sides extends in the opposite direction. The second bonding area 211 is connected to the first bonding edge 11 and part of the first The profiled edge 12 is bonded. In this structure, each second bonding area 211 extends to the second forming side 22 adjacent to it in the same direction, and the second bonding areas 211 on the adjacent two sides extend in opposite directions. A bonding side 11 and a part of the first forming side 12 are bonded, and the setting of the extension section makes it easier to form a stable S-shaped rib 4 when it is pulled apart to both sides after bonding to ensure the compr...

Abstract

The invention discloses a honeycomb core veneer with staggered reinforcing ribs and a manufacturing method thereof. The honeycomb core veneer comprises at least two original base bands, reinforcing bands are arranged between the original base bands, adjacent original base bands and reinforcing bands are uniformly adhered in a spaced manner and stretch toward two sides to from a honeycomb structurewith a plurality of hexagonal unit holes, each hexagonal unit hole has an S-shaped reinforcing rib formed by the reinforcing bands, and the S-shaped reinforcing ribs formed on adjacent reinforcing bands are arranged in a staggered manner opposite to twisting directions. The manufacturing method comprises the following steps: S1, dividing the units; S2, arranging a coating area; S3, making a board; S4, coating; S5, adhering; and S6, forming. The honeycomb core veneer has the advantages of being simple in process, low in manufacturing cost, environment-friendly to use, high in compressive strength and capable of absorbing sound and insulating heat.

Description

technical field [0001] The invention mainly relates to the technical field of forming honeycomb sandwich panels, in particular to a rib-staggered honeycomb core panel and a manufacturing method thereof. Background technique [0002] At present, because the honeycomb sandwich panel has the advantages of low cost, high specific strength, easy processing and molding, etc., the honeycomb sandwich panel gradually exerts its advantages in the fields of packaging, transportation, furniture and construction, replacing other traditional corrugated cardboard, wood, and foam plastics. And other materials, the application prospect is very broad. The core layer of the conventional honeycomb sandwich panel adopts the natural honeycomb structure, and the base material is bonded with an adhesive to form several hollow regular hexagonal prisms, and the surface material is compounded on both sides to form a composite panel with a new sandwich structure. [0003] The strength of the honeycomb...
