Method for manufacturing automobile body through carbon fiber composite

Abstract

The invention discloses a method for manufacturing an automobile body through a carbon fiber composite. The method comprises the following steps that a flexible inner mold matched with the automobile body and used for manufacturing the automobile body is inflated to be in an automobile body shape, the outer surface of the flexible inner mold is coated with the pre-glued carbon fiber composite according to the requirement for the design angle and the number of layers, and then the automobile body is formed; the flexible inner mold coated with the carbon fiber composite is placed in an outer mold to be fixed, inflated and pressurized, and then the outer mold is placed in a curing furnace to be cured; and after the carbon fiber composite is cured, natural cooling is carried out, the flexible inner mold is deflated to reduce pressure, the outer mold is opened, and the cure-molded composite automobile body is taken out. Due to the fact that the automobile body made of the carbon fiber resin composite is adopted, compared with a traditional metal material automobile body, the weight is reduced by 60% or above, the corrosion resisting performance is improved, energy absorption of the automobile body is better, and running energy consumption is reduced.

Description

technical field [0001] The invention relates to a method for manufacturing an automobile body, in particular to a method for manufacturing an automobile body with carbon fiber composite materials. Background technique [0002] High-strength carbon fiber composite materials are widely used in aerospace, aircraft, racing cars and other structures due to their light weight, high strength, designable material properties, and easy processing. Carbon fiber and its composite materials are currently the fastest growing in the world. One of the high-tech materials. With the decline of carbon fiber prices and the increase of output, carbon fiber composite materials have gradually entered the civilian market, such as wind turbine impellers, racing bicycles, F1 racing cars, golf clubs, etc. More and more carbon fiber composite materials are used. With the rapid development of new energy vehicles and electric vehicles, carbon fiber composite car frames have been used in some electric ca...

Problems solved by technology

The above technologies all use carbon fiber as a reinforcing material and various resins as a matrix for composite car bodies. Due to differences in design methods, there are differences in the composite process and final performance. None of the composite manufacturing processes has been widely used. So far, except for the mass market of carbon fiber composite car bodies in foreign countries, there is no mass market of carbon fiber composite car bodies in China.
