Embodiment 1

[0035] Embodiment 1 Manufacturing and processing of a certain engine cover

[0036] 1. Material preparation:

[0037] The carbon fiber cloth used in the experiment is 3K220g carbon fiber plain cloth provided by Lianyungang Yingyou Group, and the experimental resin is R-3895 epoxy resin provided by Xiamen Weiman Material Technology Co., Ltd.

[0038] 2. Parts manufacturing process

[0039] Through the CAE analysis of the strength and stiffness of the hood, the reinforced area of ​​the hood is designed, and the 3-layer carbon fiber cloth is cut into the shape of the reinforced part.

[0040] Cut 3-5 layers of carbon fiber cloth into the expanded size of the engine hood.

[0041] Stack the multi-layer carbon fiber cloth according to the order and size, and use a small amount of spray glue to bond and fix the two layers of carbon fiber cloth.

[0042] Lay a layer of flow guide net and a layer of release cloth on the mold, and then put the stacked multi-layer carbon fiber cloth ...

Abstract

The invention relates to the technology of machining manufacturing of automobile parts made of carbon filer composite materials, in particular to a manufacturing method of an automobile engine cover made of the carbon fiber composite materials. The manufacturing method is mainly applied to machining manufacturing of the engine cover made of the carbon fiber composite materials of different thicknesses. The process procedure includes the steps of clipping carbon fiber cloth, laying the carbon fiber cloth, arranging the multi-layer carbon fiber cloth into a die, conducting resin vacuum pouring, conducting vacuum heating and heat preservation, conducting demolding, taking out a workpiece and conducting trimming. The manufacturing method is characterized in that the carbon fiber cloth is clipped and designed, and the laid carbon fiber cloth layers in different shapes are put into the die and then subjected to resin pouring; and due to the fact that the thicknesses of the compositely formed engine cover made of the carbon fiber composite materials are different, the requirements for strength and rigidity of the engine cover are met, and the weight can be reduced.

Description

technical field [0001] The invention relates to a manufacturing technology of carbon fiber composite material automobile parts, in particular to a method for manufacturing a carbon fiber composite material engine cover, which is mainly applied to the processing and manufacturing of carbon fiber composite material engine covers of unequal thickness. technical background [0002] In recent years, the problems of environmental pollution and resource consumption have become increasingly serious. With the rapid development of the automobile industry, automobile exhaust emissions and fuel utilization are increasingly concerned by the society, and automobile lightweight has become the development trend of the automobile industry. Lightweight materials represented by high-strength steel, aluminum alloy and carbon fiber composite materials are used in automobile parts Applications in the field of advanced manufacturing are increasing day by day. [0003] Due to the high strength, hi...
