Description
Technical Field
The present disclosure relates to a composite panel.
Background
At present, a flame-retardant wear-resistant decorative plate, also called a fire-proof plate, is generally prepared into a sheet shape by impregnating a central layer, a surface wear-resistant layer and the like with resin and then performing high-temperature hot pressing. These fire retardant and wear resistant decorative panels are commonly used as decking for table tops, furniture, countertops, and the like. At present, in order to save energy, reduce emission and reduce energy consumption, the requirement of the motion carrier on light weight is higher and higher. The composite formed board surface of the flame-retardant wear-resistant decorative board, the wood board, the laminated board and the like gradually cannot meet the light-weight requirement. The aramid fiber paper honeycomb has excellent performances of light weight, high strength, flame retardance, environmental protection, corrosion resistance, fatigue resistance and the like, is widely applied to high-end fields of aerospace, military industry and the like, and the sandwich structure can meet the requirement of mechanical property and greatly reduce the weight of a product, so that the requirement of light weight can be well met. However, when the flame-retardant wear-resistant decorative plate on the current market is directly compounded with aramid fiber honeycombs, foams and other core materials to form a plate surface, the overall mechanical property of the plate surface is often relatively weak, and particularly the impact resistance is difficult to achieve an ideal effect.
With the development of technology, rail transit vehicles have higher and higher requirements for light weight. At present, aramid paper honeycomb composite materials are gradually applied to rail transit vehicles. The product is mainly a sandwich structure compounded by aramid paper honeycombs and prepreg. The prior art of the aramid fiber paper honeycomb composite material for the wall plate and the partition plate between the rail vehicles is that the aramid fiber paper honeycomb and the prepreg are compounded into a composite board, and then the composite board and the fireproof plate are subjected to composite molding. Or the aramid paper honeycomb, the glass fiber fabric and the fireproof plate are formed in a composite mode. The former has higher product cost due to the use of pre-soaking materials and multiple forming. On one hand, the mechanical property of the glass fiber fabric is inferior to that of the prepreg, the product prepared by the method has weaker performance than the prepreg, and on the other hand, the product prepared by the method is easy to cause weight increase. The prior art is not beneficial to the popularization, application and development of the aramid paper honeycomb composite material.
