A carbon fiber metro prepare, dubbed CETROVO 1.0, started passenger service on Friday within the port metropolis of Qingdao in east China’s Shandong Province.
This metro prepare contains a carbon fiber composite physique and body, which reduces the load of the automobile physique and bogie body by 25 p.c and 50 p.c, respectively, making the full car weight 11 p.c lighter in contrast with standard trains.
Liu Jinzhu, chief designer of the prepare with CRRC Qingdao Sifang Co., Ltd., mentioned the vitality consumption of every prepare might be diminished by 7 p.c throughout operation, resulting in an annual drop of about 130 tonnes in carbon dioxide emissions — which is roughly the identical as planting 101 mu (round 6.7 hectares) of bushes.
Notably, using carbon fiber supplies additionally reinforces the car’s physique, boosts its affect resistance and extends the sturdiness of its construction.
The inside of this prepare’s cabin is wealthy in carbon fiber components, starting from glossy black carbon fiber seats and armrests to the motive force’s console — all contributing to a futuristic, high-tech really feel. Because of using carbon fiber composites, the car additionally boasts enhanced vibration damping and sound isolation, making certain a smoother journey and a extra comfy expertise for passengers.
As well as, a digital twin-based clever upkeep platform, SmartCare, has been developed for the carbon fiber prepare. This platform permits sensible fault detection, real-time well being monitoring and upkeep optimization — thereby lowering total restore prices.
