With the improvement of the speed technology and equipment for rail transit vehicles , the modern vehicles has improved the requirements of light weight and noise reduction on the original design. In order to ensure the beauty and comfort, the interior accessories that are made from plywood are unable to meet the development of the modern vehicle interior decoration. As a result, a large number of light-weight new materials have emerged.
Honeycomb panels have the advantages of light weight and high rigidity, and have excellent properties for sound insulation and thermal insulation. The decorative films can be attached on the decorative surface by means of sticking or vacuum adsorption. The decorative effect is very good. Aluminum honeycomb panels have been widely used in the interior decoration of rail transit vehicles, floors, roofs, partitions, and various door panels etc.
Taking aluminum honeycomb floor as an example, the weight of plywood floor for a 25-type passenger train is about 1.5T, while the weight of aluminum honeycomb floor for a high-speed EMU is only about 0.8T, and the weight loss is extremely obvious.
