汽车轻量化用碳纤维复合材料国内外应用现状

摘要

在节能减排、开发清洁能源汽车的背景下，车用材料轻量化是目前全球汽车工业技术研发的主要目标之一。本文对国内外主要汽车制造商在汽车轻量化用碳纤维复合材料的应用现状进行概述，指出了我国汽车轻量化技术发展存在的问题。%To meet the requirements of energy-saving, emission reduction and developing new energy vehicles, lightweighting of automotive materials is one of the most important targets for technological R&D in global auto industry. In this article, recent progress on using carbon fiber reinforced composites for automobile lightweighting has been systematically reviewed based on case study of leading auto manufacturers from home and abroad. Finally, the choke points for the development of automobile lightweihting in China are summarized.
