CRRC Changchun Railway Vehicles has developed the first subway train in the world with carbon fiber composite materials. Compared to metal train, the weight of the new train is 35 percent lighter, while having significantly improved carrying capacity and energy consumption capability.
Carbon fiber composite materials train eliminates the dimensional deviation and shape deviation which due to metal welding improves the dimensional accuracy and appearance quality. Also, the train has tested more than 10 different material performances, and more than 6,000 components, typical elements and assembly parts.
Because of the antifatigue, acid and alkali corrosion and ultraviolet radiation and aging of the composite material, the service life of the new subway train has been extended to 30 years. The train is also said to be safer, more reliable and more economical.
The research and design of the new subway train was all independently done by CRRC Changchun Railway Vehicles.
