Abstract: At present, the passenger car market is developing rapidly, and the number of cars also grows accordingly. With the convenience to travel, better energy saving, environmental protection and safety have also been made a new issue in the development of modern automobile.The lightweight design of automobile bumper, an effective way to reduce environmental pollution and improve the energy saving and environmental protection of products, has already been an important automobile research direction for sustainable development. This paper analyzes material use, material processing method and bumper modeling design, and explains the relation between the lightweight of the bumper and the three factors. Advance of the processing method affects the bumper modeling design to a large extent, while the lightweight bumper modeling design can directly influence the safety and energy saving during low-speed driving. From the traditional suppression and injection processing, to the perso-nalized customization of digital 3D printing incremental technology and the application of small batch production, technology development accele-rates the innovation of products, so as to improve the harmonious unity of the vehicle shape.The molding technology of carbon fiber composite material is an effective way to realize the automobile lightweight, which not only improves the vehicle's ability to absorb and mitigate external impact, but also plays a guiding role in the automobile appearance design and transformation in the future.
