STUDY ON INSULATION OF COMPOSITE PANELS AND THEIR COMBINED STRUCTURES FOR URBAN RAIL VEHICLES

Abstract

Abstract: Fiber reinforced composites, polymer composites, sandwich panels and other basic panels and their combined structures have been widely used in urban rail vehicles. Due to their unique performance and function, as well as the diversity of the combination scheme, it is often difficult to judge whether to accept or reject during using process. Based on the experimental test data, the paper analyzes the sound insulation, such as several typical single-layer composite plates, glass fiber composite and carbon fiber composite plates, aluminum honeycomb, foam sandwich panels, and various material combinations. At the same time, a lightweight requirement is considered. Finally, the basic principles of composite selection of urban rail vehicles are proposed, which can provide reference for the selection of composite materials for urban rail vehicles.

Key words: rail vehicle, composite material, interior decoration, sound insulation
