The application of carbon fiber composite materials in the automotive industry is mainly to meet the needs of sufficient rigid performance of automobiles, and to achieve the lightweight of automobiles, carbon fiber can not only meet the global demand for energy conservation and emission reduction, but also solve the problem of energy saving and fuel saving that consumers are concerned about, so carbon fiber composite materials can be used as the mainstream material of automobiles in the future.
The density of carbon fiber is close to 1/5 of that of steel materials, and the current conventional mass of the car body is 400~500kg, while the body mass of an all-carbon fiber sports car is less than 100 kg. For every 10% reduction in vehicle mass, fuel consumption can be reduced by more than 6%, which greatly improves the endurance and reduces emissions by more than 5%. Because of its wide application prospects, carbon fiber is known as the “black gold” that is about to blow out in the 21st century. Studies have shown that car manufacturers spend more money on reducing the weight of a vehicle by 1 kg than by adding 1 horsepower.
