Although carbon fiber due to its own cost factors, resulting in its difficult to enter the mainstream automotive market, and is currently used in the high-end market for decorative parts. With the accelerated pace of carbon fiber localization, carbon fiber composites R & D speed, is expected to 2025, carbon fiber composites will be expected to become the mainstream configuration of the global automotive market, to undertake more structural parts of the production.

Automotive door panel construction

Used to replace conventional aluminum alloy parts to achieve significant weight reduction. Toyota Purus tailgate inner panel, and Lexus LC500(h) door inner panel.

Wheels
The weight of a typical aluminum alloy wheel is about 15 kg, while carbon fiber wheels can be reduced to 8 kg, making carbon fiber wheels a genuine "weight-saving device.
In addition, compared with traditional fuel vehicles, new energy vehicles, more batteries, motors and electronic control of the "three electric systems", the vehicle quality is also higher than the same level of fuel vehicles by about 10%. Under the premise of unchanged working conditions, the increase in body mass of electric vehicles will significantly shorten the range. Therefore, body lightweight is an important way to improve range.

Battery Box
Battery box body, as a protective part of the power battery for electric vehicles, has high requirements for structural design and weight, etc. After the weight and size of the battery module are determined, there are more factors to consider when designing the battery box body. First of all, the battery box body is the bearing part of the battery module, and the battery module needs to be connected to the vehicle body through it. Secondly, the power battery is generally installed in the lower part of the body, taking into account the working environment of the battery module, the battery box needs to have the module protection function, need to consider the module of the waterproof and dustproof as well as the corrosion of the road environment on the battery box, the battery box needs to be considered to withstand the vibration and impact of the vehicle operation process.


Carbon fiber materials in the application of automobiles, not only lightweight, reduce energy consumption, but also to enhance the demand for automotive safety performance. Carbon fiber wheels compared with traditional aluminum alloy wheels, lighter quality, higher strength, no metal fatigue, noise reduction is obvious. China's automotive carbon fiber has a huge market potential, carbon fiber wheels are not pushed on a large scale, mainly based on carbon fiber cost considerations.
