Carbon fiber materials are widely used in composite materials, civil engineering, aerospace and sporting goods, such as light weight, good rigidity, good energy absorption, high plasticity and corrosion resistance. However, with the increasing environmental protection calls for energy conservation and emission reduction, reducing fuel consumption has become a top priority for many car companies to improve. Reducing the weight of the vehicle and reducing the engine load is undoubtedly the best way to save energy and reduce emissions. Moreover, car accidents occur frequently, the body is rigid, and the high plasticity can greatly reduce the casualties of personnel. Therefore, in the future, carbon fiber manufacturing will gradually become a trend in the development trend of automobiles.
 
At this stage, carbon fiber manufacturing is not a blank in the automotive field. Some automakers have applied carbon fiber composites to key components such as automotive driveshafts, springs, frames and brake pads, such as racing chassis, carbon fiber brake discs, carbon fiber hubs, and drive shafts. Due to the high cost of carbon fiber, only Lamborghini, Porsche, BMW, McLaren, Mercedes-Benz, Pagani and others have studied carbon fiber bodies. First of all, BMW became the first car manufacturer to eat crabs in the field of carbon fiber manufacturing. For safety and fuel economy, BMW invests much. When a small number of automakers use an all-aluminum body (Jaguar Land Rover, Audi), the main reason is cost savings and production processes. Just as these car manufacturers were immersed in the technology of aluminum body, the technology was leading other manufacturers, and suddenly found that BMW has adopted a "black technology" such as carbon fiber to build a car.
