Carbon fiber is an important reinforcement material for manufacturing advanced composite materials. It has high strength, friction resistance and corrosion resistance, and can be widely used in aerospace, energy equipment, transportation, sports and leisure and other fields. Since its birth, advanced carbon fiber composite technology has been in the hands of developed countries for a long time. In order to get rid of the situation that the core technology is controlled by others, China began to vigorously develop the carbon fiber industry after 2000, and listed it as one of the strategic emerging industries. In addition, the 14th Five-Year Plan and the 2035 Vision Target Outline include pilot demonstration of collaborative application in the field of carbon fiber composites and strengthening the research and development of carbon fiber and its composite materials.

Under the guidance of the "double carbon" goal, the carbon fiber industry will usher in large-scale development, and the market application continues to expand. According to the 2016-2021 Global Carbon Fiber Composites Market Report of Cyo Carbon Fiber, China's carbon fiber demand increased from 19,600 tons in 2016 to 62,400 tons in 2021, with an average annual compound growth rate of 26.06% and a year-on-year growth rate of 27.69% in 2021. Domestic demand is expected to be 159,300 tons in 2025.

At present, hydrogen energy and photovoltaic are the main application fields of high-end carbon fiber products. Focusing on the demand of the downstream industrial chain such as Wind-wind hydrogen, carbon fiber enterprises are accelerating the maturation of manufacturing technology, improving the guarantee rate of raw materials in the field of new energy application, and strengthening the competitiveness of enterprises.

Under the traction of the expanding market demand, our carbon fiber industry is speeding up to the direction of more system, higher performance and lower cost. Recently, the construction project of Zhongfu Shenying Carbon Fiber Co., Ltd. with an annual output of 30,000 tons of high-performance carbon fiber has landed in Lianyungang City, Jiangsu Province. The project has built several sets of polymerization devices, raw silk production lines, carbonization production lines and supporting works. Zhang Guoliang, chairman of Zhongfu Shenying Carbon Fiber Co., LTD., introduced that the project will make full use of nuclear steam and photovoltaic power generation to realize the transformation of energy green and low carbon in the process of carbon fiber production. At the same time, it will adopt the most advanced 4.0 version of carbon fiber industrialization technology for the first time to design a new production base. To further enhance the large-scale application of Zhongfu Shenying high-performance carbon fiber products in aerospace, new energy and other fields, and create a green ecology of carbon fiber industry.

It is understood that Zhongfu Shenying in Lianyungang base as the center, the layout of Xining ten thousand tons base, Shanghai aviation application research and development base and Lianyun District new base. "The new base is based on the production technology of Xining 10,000 tons, and the intelligent level of production line and the comprehensive utilization rate of energy have been greatly improved, with a larger scale, higher level and stronger quality. The project is Zhongfu Shenying scale strategic layout to take a new step, to enhance the overall competitiveness of the company, expand market share has an important role in promoting." Zhang Guoliang said.

In recent years, with the efforts of policies and enterprises, China has continuously made new breakthroughs in the preparation and application of carbon fiber key technologies, and the related production capacity has continuously improved and the self-sufficiency rate has continuously increased. China's first 10,000-ton 48K large tow carbon fiber engineering production line in Shanghai petrochemical carbon fiber industrial base; Shanxi Steel has formed the production capacity to cover the main varieties of high performance carbon fiber in China. In order to ensure the autonomy and control of the key raw materials for domestic large aircraft, Zhongfu Shenying has continuously made breakthroughs in the production technology of T800 grade carbon fiber prepreg, and the main performance of the product meets the requirements of domestic large aircraft. Currently, the process performance evaluation and verification are being carried out...... Thanks to the continuous efforts of industry enterprises, the market share of domestic carbon fiber climbed from 31.7 percent in 2019 to 46.9 percent in 2021.

However, experts say there is room for improvement in the performance and quality stability of domestic carbon fiber, and the core equipment of carbon fiber will still need to be imported in the short term. To create an innovation matrix in key core technologies and accelerate the formation of operational capacity with international competitive advantages is the challenge faced by China's carbon fiber industry and also the long-term goal of high-quality development.

"Centering on major national strategies and the main battlefield of the national economy, central enterprises should give full play to the role of the 'national team' of science and technology innovation, make important contributions to improving the autonomy and controllability of the country's key materials and technologies, and maintain the security and stability of the industrial chain and supply chain." China Building Materials Group Party Secretary, chairman Zhou Yuxian said.

Zhou Yuxian said that Zhongfu Shenying is an important member of the new materials sector of China National Building Materials Group. China National Building Materials Group will, as always, support Zhongfu Shenying to seize the precious opportunities in the adjustment process of the global carbon fiber industry structure and layout, constantly open up new fields and win new tracks, and create a world-class carbon fiber enterprise with global competitiveness. "In the future, China National Building Materials Group will continue to support Zhongfu Shenying to grasp the new opportunities in the adjustment process of carbon fiber industrial structure and layout, accelerate the formation of green manufacturing new drivers, transform ecological and technological advantages into corporate development advantages, promote the deep coupling of industrial upstream and downstream, and build high-quality industrial clusters."
