The “Automotive Carbon Fiber and Its Composites Annual Development REPort 2020” is Officially Released
碳纤维复合材料因其优异的机械性能、防腐性、可设计性等表现，一直以来都颇受汽车制造商的青睐。自宝马在其i系列车型成功使用碳纤维复合材料后，行业对于这一“黑色黄金”材料的应用研究也在不断发展。随着国内前途K50和蔚来ES6两款量产碳纤维复合材料部件车型的亮相，让车用碳纤维在自主品牌车型上再一次华丽绽放。与此同时，碳纤维复合材料的应用范围也不断扩展。从车身、内外饰系统向底盘、动力总成系统延伸；从外覆盖件材料向结构件材料或结构增强材料延伸。然而，碳纤维的批量化应用还面临着成本、生产周期、成熟的工艺体系、有效的材料回收工艺等方面的问题。需要在解决材料、设计、回收等技术问题的同时，逐步完善相应技术体系和应用标准的建设，同时还需要建立涵盖碳纤维原丝、树脂、复合材料成型工艺及设备、结构设计、检测与评价、材料回收与再利用等全面的成熟的稳定的产业供应链。这无疑需要全行业产业链的共同努力和进步。
Carbon fiber composites have always been favored by car manufacturers for their excellent mechanical proPE rties, corrosion resistance, designability and other performance. Since BMW successfully used carbon fiber composite materials in its i-series models, the industry's research on the aPPlication of this "black gold" material has also continued to develop. With the appearance of the QIANTU K50 and NIO ES6, both of which have been in mass production, carbon fiber has once again blossomed on its own brand models. At the same time, the scope of application of carbon fiber composite materials is also exPAnding. It extends from the car body, interior and exterior trim systems to the chassis and powertrain system; from the outer cover material to the structural material or structural reinforcement material. However, the batch application of carbon fiber also faces problems in terms of cost, production cycle, mature process system, and effective material rECOvery process. It is necessary to gradually improve the construction of the corresponding technical system and application standards while solving technical problems such as materials, design, and recycling. At the same time, it is also necessary to establish a comprehensive mature and stable industrial sUPply chain covering carbon fiber strands, resins, molding equipment, structural design, testing and evaluation, material recycling and reuse. This undoubtedly requires the joint efforts and progress of the entire industry chain.
