The invention relates to the technical field of rail vehicles, and discloses a vehicle body structure of high-damping sound insulation composite materials for a rail vehicle, comprising a vehicle body, and a high-damping sound insulation structure arranged on the vehicle body and in close contact with the surface of the vehicle body, wherein the high-damping sound insulation structure comprises aplurality of damping sound insulation layers arranged in a superposed manner in the longitudinal direction, wherein the graphene material is added to each of the damping sound insulation layers. The vehicle body structure has the advantages that on the premise that the weight increase of the vehicle body structure is not obvious and the size of the vehicle body structure is basically unchanged; the sound insulation quantity of the vehicle body structure can be remarkably improved; the noise level in the vehicle can meet the limit value requirements, and the comfort degree of passengers can beimproved. The vehicle body
