01 Introduction
New energy vehicles are gradually replacing traditional fuel vehicles. The range of new energy vehicles has become the biggest obstacle to development, and lightweighting is particularly important. With the increasing demand for environmental protection and energy conservation, the global automotive industry is seeking diversified lightweight solutions. The demand for weight reduction of unsprung mass is particularly prominent, and as an important component of unsprung mass, wheels account for a large proportion of the overall mass of automobiles. One effective way to reduce weight is to use carbon fiber wheels. With the decrease in raw material and manufacturing costs, carbon fiber wheels, which were originally expensive and only used for luxury or ultra luxury car models, are gradually "declining".
