Lightweight vehicle has become a trend due to the requirement of using alternative energy.  Safe operation, cost reduction and efficiency improvement also become the top priority of industrial development. "The comprehensive solution with lightweight as the core is the best solution for safety and efficiency". Under this background, the two main materials involved in lightweight, high-strength alloy materials and composite materials, have been paid more and more attention, while high performance polymeric materials (adhesives and high-performance plastics) and high-performance composite materials (carbon fiber, glass fiber and other composite materials) have been paid more and more attention ）. 

The demand is growing rapidly. From the point of view of composite materials, taking carbon fiber as an example, the output in the last five years is 46.4% and the consumption is 49.1%. Even so, at present, China's output can only meet 30% of the market demand, most of which relies on imports. There is a big gap in the market. How to manufacture high-performance composite materials to meet the requirements of vehicle design and manufacturing involves professional knowledge of resin selection, fiber selection, layout and manufacturing process.
