One article to understand the application of carbon fiber in the field of rail transit

Relevant data shows that by 2025, China's high-speed rail mileage will exceed 38,000 kilometers, and there are more than 2,500 high-speed rail trains in service. The energy saving, environmental protection, comfort and convenience of trains have become the future development direction of high-speed trains. Because of its excellent performance, carbon fiber has attracted more and more attention and adoption by rail vehicle development companies, and its development potential is huge.
