Problems solved by technology

Although this structure has a significant effect in weight reduction, the performance of PVC material decreases at low temperatures, and there is a risk of brittle fracture; there are major problems in the installation process of the aluminum honeycomb sandwich structure, and special treatment is required for the screw installation part. to ensure sufficient nailing force
[0006] Therefore, considering the requirements of lightweight materials, environmental protection, and safety in the field of public transportation that is rapidly developing in my country, the current passenger car floors cannot fully meet the requirements for use.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of composite materials, mainly relates to the technical field of automobile interior decoration, and in particular relates to a passenger car floor with a sandwich structure. Background technique [0002] As the main load-bearing component, the floor of the passenger car requires high strength, light weight, impact resistance, wear resistance, long service life, and beautiful appearance. With the development of the national economy, people have more and more requirements for the comfort of travel vehicles. higher. In addition, the vehicle will be frequently affected by alternating loads and uncertain factors such as vibration and shock during driving, which put forward stricter requirements for the safety, environmental protection and energy saving of the new generation passenger car floor. The development strategy of advanced automotive material technology led by light weight—reducing the mass of passeng...
