Lightweighting originated from racing. As energy conservation and environmental protection have become more and more widely concerned topics, the application of lightweighting in the field of ordinary automobiles has gradually increased. Realizing automobile lightweighting is also a headache for people. As an emerging material developed in recent years, the performance of carbon fiber is obvious to all. So what kind of contribution has carbon fiber made to achieving automobile lightweighting?
To achieve lightweighting, the most important thing is to reduce the weight of the body. The weight reduction of the body depends on the material. Carbon fiber is a very light material, mainly due to its low density. The body made of carbon fiber is 30%-50% lighter than that of metal. Under no-load conditions, about 70% of the fuel consumption is used in the body mass. Therefore, the lightening of the body is of great benefit to the fuel economy and vehicle control stability of the whole vehicle.
Secondly, to achieve lightweighting is a reasonable design. The clever body design also contributes to lightweighting. Carbon fiber has the softness of textile fiber and is processable. It can be laid reasonably and play an effective role. In addition, carbon fiber can be formed by an integrated molding process.
Lightweighting of automobiles is an inevitable trend, and carbon fiber is currently the best choice. Carbon fiber can not only achieve lightweighting of the car body, but its strength, aging resistance and corrosion resistance are all outstanding. Therefore, in the process of achieving lightweighting of the car body, carbon fiber will definitely shine.
