Manufacturing process for automobile engine hood assembly of carbon fiber composite

Abstract

The invention discloses a manufacturing process for an automobile engine hood assembly of a carbon fiber composite. The manufacturing process for the automobile engine hood assembly of the carbon fiber composite is characterized by comprising the steps that (1) carbon fiber materials, PVC foam and resin are selected; (2) an RTM mould is cleaned and coated with a releasing agent; (3) the RTM mould is coated with a gel coat; (4) carbon fiber fabric comprising an automobile body outer covering part layer and an automobile body structural layer is laid, and a PVC foam layer is evenly added between the two layers; (5) the mould is closed and clamped; (6) the resin is injected into the mould; (7) curing is conducted; (8) the mould is opened, demoulding is conducted and the molded automobile engine hood assembly is taken out; and (9) the taken-out automobile engine hood assembly is polished and brightened. According to the manufacturing process for the automobile engine hood assembly of the carbon fiber composite, an inner plate of a conventional steel work is removed, the inner plate and an outer plate are integrated, one-time forming is simple in step and low in cost, it is also guaranteed that performance requirements are met at the same time, and the manufacturing process for the automobile engine hood assembly of the carbon fiber composite has relatively good application prospects.

Description

technical field [0001] The invention belongs to the technical field of automobile parts production, and more specifically relates to a manufacturing process of a carbon fiber composite material automobile engine cover assembly. Background technique [0002] With the development, people have higher and higher requirements for the shape and performance of cars. Reducing the mass of the car itself is one of the most effective measures to reduce fuel consumption and reduce emissions. The report of the World Aluminum Association pointed out that every 10% reduction in car mass can reduce fuel consumption by 6% to 8%. Most of the existing car hoods are metal structures, the overall body weight is heavy, and the power demand is large, so the requirements for the driving engine and the suspension are high, and the risk of impact and collision is high. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and to...
