Vehicle light-duty multi-functional engine hood

Abstract

The invention discloses a vehicle light-duty multi-functional engine hood. The vehicle light-duty multi-functional engine hood comprises an inner plate and an outer plate, a supporting plate is further arranged between the inner plate and the outer plate, the supporting plate is attached to the lower surface of the outer plate, the outer plate is made of carbon fiber composite materials, the supporting plate is made of interpenetrating network resin composite materials, the inner plate is made of aluminium alloy materials, and the interpenetrating network resin composite materials are CCF800Hcarbon fiber resin composite materials. Compared with an existing technology, the vehicle light-duty multi-functional engine hood has the following advantages that the vehicle lightweight technology is effectively achieved; the advantages of high strength and hardness are achieved; requirements of strength, stiffness, concave resistance and the like in the using process of the engine hood are met;in the process of being subjected by external force and collision, the safety of drivers and pedestrians in the process of collision can be furthest protected; the problem of thermal deformation of acarbon fiber hood is perfectly solved; and production process is simple, production cycle is short, and the costs of development of a lot of moulds are saved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile light-duty multifunctional engine cover. Background technique [0002] As the main component of pedestrian head collision impact, automobile hood not only affects the shape of pedestrian protection, but also its material and structure have an important impact on the safety performance of pedestrian head collision. Carbon Fiber Composite (CFC) composite material is a high-strength composite material, mainly composed of carbon fiber as a reinforcing material and a thermosetting resin as a basic material, so it has high specific strength, specific stiffness and obvious lightness. Quantify the effect. The car hood made of carbon fiber composite materials can effectively reduce pedestrian head injuries, and at the same time ensure the integrity of its own structure and reduce maintenance costs. [0003] Due to the poor toughness of carbon fiber composi...

AI Technical Summary

Problems solved by technology

[0003] Due to the poor toughness of carbon fiber composite materials in the tangential direction, in the event of a collision between vehicles or a collision between a vehicle and a wall, it will not absorb energy in the form of collapse, and it is easy for the material to be broken in a large area and penetrate into the cockpit. Driver safety phenomenon, in addition, carbon fiber composite materials will become brittle after long-term use, which also seriously affects its performance in terms of pedestrian protection. The above defects have become an important bottleneck in its application in the field of passenger vehicles
