In addition, PP honeycomb board is also applied to the production of billboards and various strength packaging boxes to meet the needs of different fields.

[0003] The Chinese utility model patent with publication number CN221851407U discloses a PP board with impact resistance and high flame resistance.

[0028] In order to improve or solve the technical problems of poor structural strength and weak bearing capacity of the existing honeycomb composite board, the utility model provides a kind of honeycomb composite board. The honeycomb composite board comprises: first plate 1, second plate 2 arranged in parallel with first plate 1, and honeycomb core material 3 arranged between first plate 1 and second plate 2;Honeycomb core material 3 includes a plurality of arrayed and inclined structural tubes, and the direction of horizontal component force transmitted by adjacent two rows of structural tubes is opposite.

[0029] Figure 1 It is the overall schematic diagram of the embodiment of the utility model a kind of honeycomb composite board. As shown in Figure 1 In one or more embodiments, the utility model a kind of honeycomb composite board includes first plate 1, second plate 2 and honeycomb core material 3, and honeycomb core material 3 is arranged between first plate 1 and second plate 2.

[0030] Continuing to refer to Figure 1 In one or more embodiments, first plate 1 and second plate 2 are arranged in parallel. The material of first plate 1 and second plate 2 is glass steel. The strength of the honeycomb composite board depends on the strength of first plate 1, the strength of second plate 2 and the strength of honeycomb core material 3. The material of first plate 1 and second plate 2 is glass steel, which can enhance the structural strength of the honeycomb composite board. Alternatively, the material of first plate 1 and second plate 2 can also be set to other suitable materials. Further, first plate 1 and honeycomb core material 3, second plate 2 and honeycomb core material 3 are formed into adhesive connection. Exemplarily, first plate 1 and honeycomb core material 3, second plate 2 and honeycomb core material 3 are bonded by two-component polyurethane glue, and finally cured and formed.

[0031] Figure 2 This is a schematic diagram of the internal structure of an embodiment of a honeycomb composite panel of the present invention. Figure 3 yes Figure 2 The arrows in the figure indicate the direction of the horizontal force component transmitted by the first row of tubes 31 and the second row of tubes 32. Figure 2 and Figure 3 As shown, in one or more embodiments, the honeycomb core material 3 is a one-piece structure. The honeycomb core material 3 comprises a plurality of tightly connected structural tubes arranged in rows horizontally and columns vertically, thereby forming a honeycomb core material 3 that matches the shape of the first sheet material 1 and the second sheet material 2. Furthermore, the honeycomb core material 3 is made of polypropylene. Alternatively, the honeycomb core material 3 may be made of other suitable materials. In one or more embodiments, each structural tube extends obliquely from the first sheet material 1 toward the second sheet material 2. The horizontal force components transmitted by the structural tubes in two adjacent rows are in opposite directions. That is, when the first sheet material 1 is subjected to positive pressure, the vertical force components of the structural tubes in the two adjacent rows are in the same direction, while the horizontal force components are in opposite directions. Specifically, the structural tubes include a first row of tubes 31 and a second row of tubes 32. The horizontal force component of the first row of tubes 31 is in the opposite direction to the horizontal force component of the second row of tubes 32. The first row of tubes 31 includes a plurality of first inclined tubes extending obliquely along a first direction, forming a first angle 34 with the first sheet material 1. The first angle 34 is an acute angle. The second row of tubes 32 includes a plurality of second inclined tubes extending along a second direction. The second direction forms a second angle 35 with the second plate 2. The second angle 35 is also an acute angle. The first angle 34 and the second angle 35 have the same value. Furthermore, the first angle 34 and the second angle 35 have an angle range of 30° to 60°. For example, the first angle 34 and the second angle 35 have angles of 30°, 45°, and 60°. Figure 2 and Figure 3 This is a schematic diagram of a honeycomb composite panel when the first angle 34 and the second angle 35 are 45°. Furthermore, the structural tubes are quadrangular tubes to better fill the gaps between the honeycombs. Furthermore, a support plate 4 is arranged below the second plate 2 to support the honeycomb composite panel for testing and verification.

[0032] Table 1 below is a comparison of simulation data of honeycomb panels.

[0034]

[0035] Table 1

[0036] As shown in Table 1, when the plate size is 500*180*20mm, and the first plate 1 is subjected to a uniform pressure of 0.5Mpa / m 2When the first angle 34 is 45°, the tension is equal to the pressure, and the load-bearing mechanical properties are the largest; that is, when the first angle 34 and the second angle 35 are 45°, the optimal angle, the maximum deformation of the honeycomb composite board is the smallest, which is reduced by 19.7% compared with the ordinary six-rib honeycomb board, and the equivalent stress is reduced by 10.37%.

[0037] Figure 4 is another embodiment of the internal structure of the honeycomb composite board of the utility model, Figure 5 is Figure 4 the enlarged schematic view of B in the figure. Figure 4 and Figure 5 As shown in the figure, in another embodiment, the honeycomb core material 3 includes a plurality of rows of single-row pipes 33 stacked in sequence, and each row of single-row pipes 33 includes a plurality of structural pipes. That is, each row of single-row pipes 33 exists independently, and is stacked horizontally to form the honeycomb core material 3. The single-row pipes 33 arranged in rows independently transmit force when subjected to stress, and due to the action and reaction, the first plate 1 and the second plate 2 become carriers of the transmitted force, and form horizontal components with opposite directions and equal sizes on the first plate 1 and the second plate 2, which can better disperse the pressure and improve the stress performance of the honeycomb composite board in the horizontal direction. Figure 4 and Figure 5 The figure shows the honeycomb composite board when the angle value of the first angle is 60°.

[0038] From the perspective of mechanics, when the structural pipe is placed vertically, the structural pipe will transmit the pressure downward and to the second plate 2 when subjected to positive pressure, and the pressure is relatively concentrated in the vertical direction. The structural strength of the honeycomb composite board is related to the strength of the structural pipe and the strength of the first plate 1 and the second plate 2. When the structural pipe is placed obliquely, the first plate 1 is mainly subjected to pressure, and the second plate 2 is mainly subjected to tension. The more dispersed the force of the first plate 1 and the second plate 2, the stronger the ability of the honeycomb composite board to bear pressure. The structural pipe releases the pressure in the horizontal and vertical directions, so that the pressure is no longer concentrated in the vertical direction, thereby having better mechanical properties to bear more pressure.

[0039] The single oblique direction of the structural pipe will make the stress of the first plate 1 and the second plate 2 too concentrated, and the direction consistent with the oblique direction will cause all the horizontal components to converge together along the oblique direction. The horizontal component directions of the two adjacent rows of structural pipes are opposite, which avoids the horizontal components of the first plate 1 and the second plate 2 from converging to one side.

[0040] The technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
