A light-duty multifunctional engine cover for automobiles

Abstract

The invention discloses a light-duty multifunctional engine cover for automobiles, which comprises an inner panel and an outer panel, and a support panel is arranged between the inner panel and the outer panel, the support panel is arranged close to the lower surface of the outer panel, and the outer panel is made of carbon fiber composite material Production, the support plate is made of interpenetrating network structure resin composite material, the inner plate is made of aluminum alloy material, and the interpenetrating network structure resin composite material is CCF800H carbon fiber resin-based composite material. Compared with the prior art, the present invention has the following advantages: effectively realize the lightweight technology of automobiles; the advantages of high strength and high hardness meet the requirements of strength, rigidity and anti-dent performance of the engine cover during use; , which can protect the safety of drivers and pedestrians in the collision process to the greatest extent; perfectly solve the problem of thermal deformation of carbon fiber hood; the production process is simple, the production cycle is short, and a lot of mold development costs 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
