Embodiment 1

[0019] See attached figure 1 , a high-strength and lightweight multi-layer carbon fiber special-shaped bulkhead panel. The carbon fiber special-shaped bulkhead panel includes an outer panel 1, a structural foam sandwich 2, and an inner panel 3 from the outside to the inside. The structural foam sandwich 2 is used to strengthen the cabin wall. The impact resistance of the panel increases the load ratio of the cabin, and also reduces the overall quality of the panel. The outer panel 1, the structural foam sandwich 2, and the inner panel 3 are bonded with each other by embedding resin through a vacuum introduction process, and the vacuum introduction process can make the airtightness between the outer panel 1, the structural foam sandwich 2, and the inner panel 3 Better, the cabin looks more beautiful. The outer panel 1 is formed by gluing and pressing four layers of carbon fiber cloth, and the inner panel 3 is formed by gluing and pressing three layers of carbon fiber cloth. Th...

Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 is that the outer panel 1, the structural foam sandwich 2, and the inner panel 3 are bonded to each other by gluing, and the first layer of the outer panel 1 is made of carbon fiber plain cloth. , the laying angle of the second layer of carbon fiber cloth of the outer covering plate 1 is -45°, the laying angle of the third layer of carbon fiber cloth of the outer covering plate 1 is 90°, and the laying angle of the fourth layer of carbon fiber cloth of the outer covering plate 1 is 45°, The laying angle of the first layer of carbon fiber cloth of the inner cover plate 3 is -45°, the laying angle of the second layer of carbon fiber cloth of the inner cover plate 3 is 0°, and the laying angle of the third layer of carbon fiber cloth of the inner cover plate 3 is 45°. The grade of carbon fiber cloth is M40.

[0024] Other structures are consistent with Embodiment 1.

Embodiment 3

[0026] The difference between this embodiment and Embodiment 1 is that the angle between the two adjacent layers of carbon fiber fabrics of the outer panel 1 and the inner panel 3 is 60°C after laying, and the carbon fiber fabrics of the outer panel 1 and the inner panel 3 The specific laying angle is:

[0027] The first layer of the outer panel 1 is made of plain carbon fiber cloth, the laying angle of the second layer of carbon fiber cloth of the outer panel 1 is 60°, and the laying angle of the third layer of carbon fiber cloth of the outer panel 1 is 0°. The laying angle of the fourth layer of carbon fiber cloth of mask 1 is -60°, and the density is 300g / m 2 , the laying angle of the first layer of carbon fiber cloth of the inner cover plate 3 is -60°, the laying angle of the second layer of carbon fiber cloth of the inner cover plate 3 is 0°, and the density is 400g / m 2 , the laying angle of the third layer of carbon fiber cloth of the inner panel 3 is 60°, and the densi...

Abstract

The invention discloses a high-strength and lightweight multi-layer carbon fiber special-shaped bulkhead panel. The panel includes an outer panel, a structural foam sandwich, and an inner panel from the outside to the inside. The outer panel, the structural foam sandwich, and the inner panel The plates are bonded with each other by gluing or vacuum introduction method, the outer cover plate is made of at least 4 layers of carbon fiber cloth, and the inner cover plate is made of at least 2 layers of carbon fiber cloth. As a result, the edges of each layer of carbon fiber cloth of the outer cover panel and the inner cover panel are overlapped and glued and pressed together. The panel of the cabin body manufactured by adopting the laying design of the present invention has the advantages of corrosion resistance, high load ratio, low density and light weight, and the laying design of the present invention is simple in structure and strong in operability.

Description

technical field [0001] The invention relates to the technical field of carbon fiber composite materials, in particular to a high-strength and lightweight multi-layer carbon fiber special-shaped bulkhead board. Background technique [0002] With the rapid development of carbon fiber composite materials, carbon fiber composite materials are widely used in aerospace, automobiles, wind power blades, sports and leisure and other fields due to their corrosion resistance, high specific strength, and light weight. [0003] Traditional shelters are generally assembled from polyurethane sandwich panels through connectors, and their wall panels are generally composed of aluminum alloy outer skin layers, steel skeletons (or aluminum skeletons), polyurethane foam sandwich cores, and aluminum alloy inner skin layers. The cabin wall plate made of metal skin has the problems of easy corrosion, large mass, low load ratio and low specific strength. [0004] In the prior art, there are many d...
