The invention belongs to the technical field of composite materials, and discloses a passenger car floor of a sandwich structure. The passenger car floor of the sandwich structure is provided with a surface layer (2), a core layer (1) and a surface layer (2) which are arranged from top to bottom; the surface layer (2) is a glass fiber fabric reinforced resin-based composite material layer with the thickness of 0.5-2.5mm and the density of 1800-2200kg/m<3>; the core layer (1) is formed by combining a reinforcement formed by a fiber, or a fiber fabric, or a compound of the fiber and the fiber fabric, and a base body which is hard polyester foam obtained by foaming polyethylene resin; the core layer (1) has the thickness of 7-20mm, and the density of 200-500kg/m<3>. The passenger car floor has sufficient mechanical performance, installation reliability and excellent medium resistance, the pressing resistance and light weight of the passenger car floor are guaranteed, and meanwhile the effects of temperature preservation, sound insulation and noise reduction are achieved.
