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...
