The lightweighting of automobiles originated from racing, and with energy conservation and environmental protection becoming increasingly popular topics, the application of lightweighting in the field of ordinary automobiles has gradually increased. However, achieving lightweighting in automobiles is also a headache for people. Carbon fiber, as a new material developed in recent years, has obvious performance. So, what role does carbon fiber play in achieving lightweighting in automobiles?

To achieve lightweighting of automobiles, the main approach is to reduce the weight of the body, which relies on manufacturing materials. Carbon fiber is an extremely lightweight material that mainly depends on its low density. The body made of carbon fiber is 30% to 50% lighter than metal. Under no-load conditions, about 70% of the fuel consumption is used for the body mass. Therefore, a lighter vehicle orientation is of great benefit to the fuel economy and vehicle control stability of the entire vehicle.

Secondly, achieving lightweighting is a reasonable design, and clever body design also contributes to lightweighting. Carbon fiber has the softness of textile fibers and processability, which can be laid out reasonably and play an effective role. In addition, carbon fiber can adopt integrated molding technology.

Automobile lightweight is an inevitable trend, and carbon fiber is a good choice at present. Carbon fiber can not only achieve lightweight, but also its strength, aging resistance and corrosion resistance are outstanding. Therefore, carbon fiber will certainly play a great role in the process of realizing vehicle body lightweight.
