6月26日，全球首列用于商业化运营的碳纤维地铁列车“CETROVO 1.0 碳星快轨”在山东青岛正式发布。

China has unveiled the world's first commercially operational metro train built with carbon fiber materials, marking a significant leap in eco-friendly urban transportation technology.

该列车较传统地铁车辆减重11%，具有更轻更节能等显著优势，引领地铁列车实现全新绿色升级。

车身更轻，更节能
预计年内投入运营

传统地铁车辆主要采用钢、铝合金等金属材料，受制于材料特性，面临减重瓶颈。碳纤维因具有轻质、高强度、抗疲劳、耐腐蚀等优点，被称为“新材料之王”，它的强度是钢铁的5倍以上，但重量不到钢铁的四分之一，是轨道车辆轻量化的绝佳材料。

The innovative train utilizes carbon fiber composites, revolutionary materials known for their strength-to-weight ratio. "By using this 'king' of new materials, the train achieves an impressive 11 percent weight reduction compared to traditional metal models," said Liu Jinzhu, a senior designer at CRRC Qingdao Sifang.

该车的车体、转向架构架等主承载结构采用碳纤维复合材料制造，实现了车辆性能的全新升级，具有更轻更节能、强度更高、环境适应力更强、全寿命周期运维成本更低等技术优势。

Despite its lighter frame, the carbon fiber construction doesn't compromise on strength. Liu said the components offer superior resistance to impact and fatigue compared to traditional metals, ultimately extending the train's life span. The reduced weight also translates to less wear on wheels and rails, minimizing maintenance requirements.

与传统金属材料的地铁车辆相比，该碳纤维地铁车辆的车体减重25%，转向架构架减重50%，整车减重约11%，运行能耗降低7%，每列车每年可减少二氧化碳排放约130吨，相当于植树造林101亩。

That translates to a lighter body, with the weight savings directly translating into a 7 percent reduction in energy consumption, leading to an annual decrease of 130 metric tons of carbon emissions. The environmental benefit is equivalent to planting roughly 6.7 hectares of forest.
