Problems solved by technology

[0004] Composite panels are used as parts in aircraft, and they need to be made of the lightest and high-strength materials, such as honeycomb core structure panels. If the hexagonal honeycomb core deforms too much during structural adjustment, the hexagonal shape will easily be overstretched. elongation, etc., which affects the bearing capacity of the entire composite panel, and the composite panel is more susceptible to damage and fracture

Embodiment 1

[0041] Such as Figure 1-5 As shown, a multi-sandwich component composite board device for a transportation tool according to the present invention includes an upper layer board 1, a bottom board 2, and a sandwich composite part 3, and the upper end of the sandwich composite part 3 is connected to the upper layer board 1 , the bottom plate 2 is connected under the sandwich composite part 3;

[0042] The sandwich composite part 3 is provided with a heat conduction layer 31, a force layer 32, and a sandwich layer 33. The upper end of the heat conduction layer 31 is connected with an upper plate 1, and the bottom plate 2 is connected below the force layer 32. The heat conducting layer 31 is connected above the sandwich layer 33, and the force layer 32 is connected below the sandwich layer 33;

[0043] Wherein, the sandwich layer 33 is provided with a structural panel 331 and a cell 332, the cell 332 and the structural panel 331 are integrated and arranged through, and the struct...

Embodiment 2

[0048] Such as Figure 6-7 As shown: wherein, the heat conduction layer 31 is provided with a frame plate q1, a heat conduction sheet q2, and a flat surface q3. There is a heat conduction sheet q2, and the heat conduction sheet q2 is a circular ceramic material block structure, which has thermal conductivity, the bonding degree of the frame plate q1 is good, and the bonding degree between the structural layers of the frame plate q1 is good , so that its top and bottom can be better adhered to foreign objects, so that the heat conduction sheet q2 has a heat conduction effect on the sandwich layer 33;

[0049] Wherein, the force layer 32 is provided with a bonding plate w1, a force plate w2, and a buffer layer w3, the bonding plate w1 is fixed under the force plate w2, and the buffer layer w3 is located between the bonding plate w1 and the buffer layer w3. Between the load plates w2, the load plate w2 is a soft resin plate-like structure with a certain thickness, the buffer lay...

Abstract

The invention discloses a multi-sandwich component composite board device of a transportation tool. Belongs to the field of composite boards and comprises an upper layer board, a bottom layer board and a sandwich composite portion, the upper layer board is connected to the upper end of the sandwich composite portion, the bottom layer board is connected to the lower portion of the sandwich composite portion, the sandwich composite portion is provided with a heat conduction layer, a force layer and a sandwich layer, the upper layer board is connected to the upper end of the heat conduction layer, and the bottom layer board is connected to the lower portion of the force layer. By means of small-amplitude stretching adjustment after the hexagonal plate frame is stressed, the cell structure can be conveniently adjusted, external force can be borne in time, the drum block is compressed or extended, the size of a spherical structure is changed, the elastic supporting force on the drum block is different, the drum block is matched with the change of the drum block, the non-swelling state of the drum block is changed, and the angle change of the inner angle of the hexagonal plate frame is controlled in an auxiliary mode in cooperation with the drum block. The cells flexibly bear external force only through small-amplitude change, and the situation that the bearing effect is reduced due to the fact that the hexagonal shape is too large in change degree, deforms and loses reset force is avoided.

Description

technical field [0001] The invention belongs to the field of composite boards, and more specifically relates to a multi-sandwich component composite board device for transportation tools. Background technique [0002] In the prior art, a composite board is a board with different functions and layers of different materials. The composite board can be used as a structural part in transportation. The multi-sandwich board is a kind of composite board. Its core material contains two compound of two or more. [0003] Based on the above-mentioned inventor's discovery, the multi-sandwich composite panel of existing vehicles has the following deficiencies: [0004] Composite panels are used as parts in aircraft, and they need to be made of the lightest and high-strength materials, such as honeycomb core structure panels. If the hexagonal honeycomb core deforms too much during structural adjustment, the hexagonal shape will easily be overstretched. Changes such as elongation will af...
