Lightweight

Automobile lightweight is the core technology and important development direction of the automotive industry, and also the development strategy of the national manufacturing industry. With the rapid development of lightweight automobiles and new energy vehicles, composite materials have been widely recognized as a lightweight and high-performance material in the automotive industry. Currently and for a considerable period in the future, they will be the key to the development of new energy vehicles. If the production of new energy vehicles increases at a compound annual rate of 20% in the next decade, the composite material market size will exceed trillion yuan by 2030. Composite materials, as one of the most effective and reliable lightweight materials for automobiles, will undoubtedly play an important role in the lightweight process of new energy vehicles.
