China develops carbon fiber metro car

Chinese train car maker CRRC Changchun Railway Vehicles announced that it has developed a metro train made of carbon fiber, which is more durable and energy saving. 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.
The new metro car is 35 percent lighter than traditional metal ones, which can effectively improve its carrying capacity, save energy and operational cost, and reduce the wear and tear on the subway line.
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, according to experts of 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.
