Abstract

The invention discloses a composite material for a high-speed railway top board. The composite material comprises an outer aluminum plate, a reinforced composite material and an inner aluminum plate,wherein the reinforced composite material is arranged between the outer aluminum plate and the inner aluminum plate, the reinforced composite material includes a surface reinforcing material and a core material, the surface reinforcing material includes a sound-insulating flame-retardant layer, a prepreg layer, an impact-resistant layer, a strength layer, and a rigid structural layer, and the corematerial is a honeycomb core material. The structural design of the material is reasonable, and the selected novel reinforced composite material not only reduces the weight of a vehicle body, reducesenergy consumption, increases the impact resistance and sound insulation and flame retardant performance of the high-speed railway top board, and enhances the safety and comfort performance of a high-speed railway.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a composite material for a roof plate of a high-speed train. Background technique [0002] With the progress of social civilization and the improvement of living standards, urban rail transit has developed rapidly in recent years in order to meet the growing traffic needs of the people. China has entered the era of high-speed rail. While people have higher requirements for the convenience and speed of high-speed trains, they also have higher and higher expectations for the safety, comfort and reliability of high-speed trains. [0003] The roof of the high-speed rail car not only needs to resist the stress and high wind pressure caused by the vibration of the high-speed rail car body at high speeds, but also needs to have good flame retardancy and noise reduction and sound insulation performance. The roof of traditional high-speed trains uses FRP. Although FRP can ensure the st...
