Problems solved by technology

Although the engine hood is made of carbon fiber reinforced composite materials to meet the requirements of lightweight, but because the engine hood is a one-piece structure, the inner panel is canceled, so it is impossible to set the corresponding reinforcement structure on the upper or lower panel, which will lead to its overall strength is lacking

Abstract

The invention discloses a carbon fiber composite material automobile front cover. The carbon fiber composite material automobile front cover comprises an external plate and an internal plate which arebonded with each other; the external plate and the internal plate are made of a carbon fiber composite material of an integral course; a net-shaped reinforcing part is arranged at the middle part ofthe internal plate; a lock catch reinforcing plate and a hinge fixing support are bonded on the internal plate; and a reinforcing course is clamped in the integral course on which the lock catch reinforcing plate and the hinge fixing support are arranged. Light weight is realized on the premise of satisfying performance requirements.

Description

technical field [0001] The invention relates to the field of automobile composite materials, in particular to a carbon fiber composite automobile front cover. Background technique [0002] With the increase of car ownership in the world, a series of problems such as energy shortage and environmental pollution have become increasingly prominent. Lightweight vehicles can reduce vehicle quality, improve fuel efficiency / cruising range, and reduce costs. However, the fuel consumption regulations of traditional fuel vehicles and the cruising range of new energy vehicles are increasingly urgent, and the lightweight of automobiles ushers in a new round of development opportunities. [0003] The front cover of the car is one of the important parts of the car body. At present, the front cover of the car is generally made of metal materials such as steel or aluminum alloy through sheet metal stamping and welding processes, and the number of parts is large. The steel front cover has t...
