China develops subway car made of carbon fiber
CRRC Changchun Railway Vehicles, a subsidiary of State-owned trainmaker CRRC, announced that it has developed subway train made of carbon fiber.
The company said the new subway car is 35 % 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, 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.
CRRC Changchun has more than 18,000 employees and annually manufactures more than 8,000 trains. Its products have been exported to more than 20 countries and regions, including the United States, Australia and Brazil.
The advance will lead to the mass application of carbon fiber as a material in the area of rail transit, noted the company. While it did not say when it plans to apply carbon fiber in mass production, it said its intellectual property rights guaranteed the mass adaptation of the material.
