Abstract

The invention provides a composite board, a train body structure and a maglev train. The composite board comprises a supporting framework and a first carbon fiber layer which are located on one side of the supporting framework and fixedly connected with the supporting framework; a sound insulation layer which is located on the side, facing the supporting framework, of the first carbon fiber layer, and the sound insulation layer is connected with the first carbon fiber layer; and a second carbon fiber layer which is connected to the side, away from the first carbon fiber layer, of the sound insulation layer. According to the composite board, the train body structure and the maglev train provided by the invention, the carriage weight of the high-speed rail, the subway or the maglev train can be effectively reduced, the weight reduction of the train body is facilitated, and the improvement of the running speed of the high-speed rail, the subway, the maglev train or aerospace equipment is facilitated.

Description

technical field [0001] The application belongs to the technical field of rail transit, and in particular relates to a composite board, a car body structure and a magnetic levitation train. [0002] technical background [0003] With the development of high-speed rail, subway, maglev train technology and aerospace equipment and other technologies in recent years, it has brought great convenience to people's travel and life. People's travel is increasingly dependent on high-speed rail, subway and other means of transportation. , and also pose new challenges to the safety of high-speed rail and subway operations. [0004] At present, the car body of high-speed rail and subway usually includes an aluminum alloy frame and an aluminum alloy shell fixed on the aluminum alloy frame, and the aluminum alloy shell is fixed by bolts or screws. The aluminum alloy housing has high strength and can provide sufficient operational safety. [0005] However, the overall weight of the aluminum...
