Embodiment Construction

[0010] A lightweight component of an automobile using a composite material molding process, using the following process,

[0011] The sheet or roll of long glass fiber is formed by blister equipment to obtain the surface layer of the component. The blister mold is a single-sided mold structure. The blister mold is equipped with water channels, air channels and vacuum chambers. The water channels are used for mold temperature control. Control, air circuit and vacuum cavity are used for vacuum adsorption forming of plates. During plastic forming, mold temperature machine setting temperature: 1st and 4th quarters: 95±5°C; 2nd, 3rd quarters: 90±5°C; heating time: 65°C ±10s; Secondary vacuum (molding time): 50s; Air cooling delay: 30s; Air cooling time: 20s; Mold temperature: 80±5°C (within 3min after the device is turned on);

[0012] The surface layer of the component and the polyurethane fiberglass material are foamed and molded through the foaming mold and foaming equipment. Th...

Abstract

The invention discloses an automobile lightweight component adopting the composite formation technology. According to the automobile lightweight component adopting the composite formation technology,after blister formation is conducted on long glass fiber, foamed hot-press forming is conducted on a formed surface layer and polyurethane glass fiber, and then the automobile lightweight component isobtained. The automobile lightweight component adopting the composite formation technology has the characteristics of overall appearance, high rigidity, light weight, low investment cost, flexible production manner and the like. The automobile lightweight component has good thermal stability and excellent mechanical performance. The automobile lightweight component, as a molded piece, can achievemore excellent mechanical performance and good appearance.

Description

technical field [0001] The invention relates to the technical field of automobile lightweight, in particular to a lightweight automobile component. Background technique [0002] Some parts on the car, such as the shroud, deflector, side shield, etc. on the heavy truck, are generally made of SMC materials after molding. This kind of exterior trim produced is not strong enough, relatively heavy, and the application effect is not very good. Contents of the invention [0003] The invention provides a light-weight and high-strength automotive lightweight component using a composite material molding process. [0004] The technical scheme provided by the invention is: [0005] A light-weight component of an automobile using a composite material molding process, using the following process, [0006] The sheet or roll of long glass fiber is formed by blister equipment to obtain the surface layer of the component. The blister mold is a single-sided mold structure. The blister mol...
