On the afternoon of December 9th, Zhang Jin, Deputy Secretary of the Huangpi District Committee and District Mayor of Wuhan, led a team to visit Jinggong Technology to conduct research on the industrial application of lightweight rail transit and carbon fiber composite materials. Industry experts such as Wang Chunsheng, Deputy Chief Engineer of CRRC Changke, and Lou Yufei, General Manager of Wuhan Changke, participated in the research. Sun Guojun, Chairman of Jinggong Technology, and Li Aijun, President, warmly received and exchanged ideas with other leaders.

Accompanied by Chairman Sun Guojun, Mayor Zhang Jin and his delegation visited the company's smart technology exhibition hall. From the technological breakthroughs of carbon fiber full chain equipment to the display of terminal products of composite materials in wind power energy, aerospace, automotive industry, sports and leisure fields, the research team had an immersive experience of the broad application prospects of carbon fiber composite materials and the industrialization strength of precision technology.

At the symposium, Chairman Sun Guojun introduced the technological accumulation and industrialization achievements of Jinggong Technology in the entire industry chain of carbon fiber "equipment materials application", the engineering progress and production plan of Jinggong Huazhong Intelligent Manufacturing Industry Base, and emphasized the company's practical path of promoting structural lightweight upgrading with the "carbon fiber+" strategy. He stated that in the future, Jinggong (Wuhan) Composite Materials will fully integrate into the Wuhan rail transit equipment industry chain, helping high-performance carbon fiber materials achieve large-scale and daily applications in the central China rail transit.

Mayor Zhang Jin highly recognizes the innovative achievements and industrial layout of Jinggong Technology in the field of carbon fiber. He pointed out that the Huangpi District Rail Transit Equipment Manufacturing Base has begun to take shape, and lightweight is an important direction for industrial upgrading. The application prospects of carbon fiber composite materials are broad. Huangpi will continue to optimize the business environment, support the accelerated construction and early production of the Jinggong Huazhong Intelligent Manufacturing Industry Base, promote the innovative application of carbon fiber new material technology in rail transit equipment on a large scale, and work together to create demonstration application scenarios for carbon fiber rail transit equipment.

During the symposium, industry experts such as Wang Chunsheng, Deputy Chief Engineer of CRRC Changke, and Lou Yufei, General Manager of Wuhan Changke, conducted in-depth discussions on the current application status, technical difficulties, and future trends of carbon fiber composite materials in rail transit.

The CR450 high-speed train prototype is undergoing operational assessment, source from People's Daily.

Currently, rail transit is developing towards high-end and material innovation driven direction, with material innovation being one of the core driving forces. The mass application of this material in rail transit equipment, from the "CETROVO 1.0 Carbon Star Fast Rail" in Qingdao to the "World's Fastest High Speed Railway" CR450 Fuxing high-speed train, has resulted in a weight reduction of over 10% and an increase in CR450 speed to 400 kilometers per hour. The demand for lightweight composite materials in this field has shown a significant annual growth rate and is becoming a new growth engine.

This research exchange has laid a solid foundation for substantive cooperation in the field of lightweight rail transit in the future. Next, Jinggong Technology will continue to rely on the technological advantages of the entire carbon fiber industry chain, fully promote the deep integration of carbon fiber technology with the rail transit industry, and make greater contributions to the high-end, lightweight, and green development of China's rail transit equipment.

In 2018, CRRC Changchun Railway Vehicles Co., Ltd. successfully developed the world's first all carbon fiber body, which adopts a thin-walled cylindrical overall load-bearing structure design to achieve a weight reduction of 35%. At the same time, it verified the feasibility of using domestic carbon fiber materials in the main load-bearing structure of rail vehicles. This technological breakthrough provides a replicable implementation path for large-scale industrial production of rail transit equipment.
