國產全碳纖維複合材料地鐵車體亮相

A leading Chinese train car maker said that it has developed subway train made of carbon fiber, which is more durable and energy saving.

國內頂尖列車製造商中車長春軌道客車有限公司日前表示，他們已研發出更耐用、更節能的碳纖維製造的地鐵車體。

CRRC Changchun Railway Vehicles Co 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.

中車長春稱，新型地鐵車體比傳統金屬車體的重量輕了35%，可有效提高運載能力、節約能源和運營成本，並減少對地鐵線路的磨損。

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.

中車長春的專家稱，由於碳纖維具有更好的抗疲勞、耐腐蝕、耐紫外線的性能，這種材料製成的地鐵列車的使用壽命至少將達30年。

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.

此外，碳纖維的隔熱、隔音性能也比傳統金屬優異，這使得新型列車運行時更加節能且噪音更小。

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.

該公司的專家表示，在開發新車型的過程中，中車長春完全依靠自己的技術創新，因此擁有新產品的全部知識產權。

A leading trainmaker in the world, 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.

作爲世界領先的列車製造商，中車長春有超過18000名員工，每年生產8000多輛列車。其產品已出口到包括美國、澳大利亞和巴西在內的20多個國家和地區。
