编者按:轻量化是汽车工业实现可持续发展的重要途径,尤其是近年来,各国针对汽车行业推出了愈加严苛的燃油经济性、排放、回收等标准,在此背景下,轻量化势在必行。目前轻量化技术主要有两个方向,一是汽车结构和材料加工工艺的优化设计,二是使用能够满足要求的更轻质的替代材料。其中,采用轻量化的替代性材料是业内普遍认同的前景最为可观的汽车轻量化路径。
Editor’s note: Lightweighting is an important way for the automotive industry to achieve sustainable development. In particular, in recent years, various countries have introduced more stringent standards for fuel economy, emissions and recycling for the automotive industry. In this context, Will do. At present, there are two main directions for light-weight technology. One is the optimization of automobile structure and material processing technology, and the second is the use of lighter alternative materials that meet the requirements. Among them, the use of lightweight alternative materials is widely recognized in the industry’s most promising car lightweight path.
