The “Automotive Carbon Fiber and Its Composites Annual Development REPort 2020” is Officially Released
碳纖維複合材料因其優異的機械性能、防腐性、可設計性等表現，一直以來都頗受汽車製造商的青睞。自寶馬在其i系列車型成功使用碳纖維複合材料後，行業對於這一“黑色黃金”材料的應用研究也在不斷髮展。隨著國內前途K50和蔚來ES6兩款量產碳纖維複合材料部件車型的亮相，讓車用碳纖維在自主品牌車型上再一次華麗綻放。與此同時，碳纖維複合材料的應用範圍也不斷擴展。從車身、內外飾系統向底盤、動力總成系統延伸；從外覆蓋件材料向結構件材料或結構增強材料延伸。然而，碳纖維的批量化應用還面臨著成本、生產週期、成熟的工藝體系、有效的材料回收工藝等方面的問題。需要在解決材料、設計、回收等技術問題的同時，逐步完善相應技術體系和應用標準的建設，同時還需要建立涵蓋碳纖維原絲、樹脂、複合材料成型工藝及設備、結構設計、檢測與評價、材料回收與再利用等全面的成熟的穩定的產業供應鏈。這無疑需要全行業產業鏈的共同努力和進步。
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.
基於此，中國汽車材料網及汽車輕量化在線研究團隊通過行業調研，對年度車用碳纖維技術進展、最新應用案例等進行整理，《車用碳纖維及其複合材料年度發展報告》2020版即將發佈！在過去一年裡，車用碳纖維領域有哪些新技術進展？讓我們一起來了解一下吧~
