China develops subway car made of carbon fiber
China has developed subway train cars made of carbon fiber, reported local media on Sunday, citing a leading Chinese train car maker.
The new train car features lightness, energy saving and longer operation time, said experts from CRRC Changchun Railway Vehicles. It is about 35 percent lighter than traditional ones made of metal, decreasing the wear on the subway track. It can also effectively improve carrying capacity, and reduce energy consumption and operation cost.

As carbon fiber can better resist fatigue, corrosion, and UV radiation, subway cars made of such material are expected to have an operational life of at least 30 years, said experts with CRRC Changchun.
In addition, the thermal and sound insulation performance of carbon fiber is also better than traditional metal, which makes the new car more energy-saving and less noisy during operation.
During the development of the new car, CRRC Changchun relied totally on its own technological innovation, thus owning the full intellectual rights of the new product, said experts with the company.
A leading train maker in the world, CRRC Changchun has more than 18,000 employees and annually manufactures more than 8,000 train cars. Its products have been exported to more than 20 countries and regions, including the US, Australia and Brazil.
