The maintenance is generally not good, so it can only be replaced. Advantages of carbon fiber composites
High strength is the best material for light-duty and high-strength automobiles. Its weight is only one fourth of that of steel, while its strength is more than four times that of steel;
Small coefficient of thermal expansion and cold contraction, high dimensional stability in extreme weather conditions, not easy to deform;
When encountering strong impact force, it will be broken into countless small pieces, which can absorb a lot of impact energy and has high safety.
The price of carbon fiber car body is very high. The cost of making a car body is nearly 60000 yuan, but the advantages are also very obvious, as follows:
Lightweight, after carbon fiber is applied to automobile, the biggest benefit to automobile manufacturing is automobile lightweight, which directly affects the improvement of automobile energy saving, acceleration and braking performance;
Safety: lightweight body can make the center of gravity of the whole vehicle move down, improve the handling stability of the vehicle, and make the vehicle run more safely and stably. Carbon fiber composite has excellent energy absorption performance, and its collision absorption capacity is three to four times higher than that of steel and three to four times higher than that of aluminum, which further ensures the safety of the vehicle;
Comfort: carbon fiber composite has high vibration damping. It takes 9 seconds for light alloy to stop vibration, and 2 seconds for carbon fiber composite to stop vibration. Therefore, the application of carbon fiber in automobile makes great contribution to the improvement of vehicle NVH, which will greatly improve the driving comfort of automobile.
