The carbon fiber industry welcomes “dual carbon” development opportunities
Known as the “King of New Materials“, Carbon Fiber New chemical materials that are both “light” and “hard” have low specific gravity and high strength, making them widely used in wind turbine blades, aerospace, sports and leisure, automobiles and other fields. As my country moves towards its carbon peak and carbon neutral goals, carbon fiber is expected to be widely used in new energy, equipment manufacturing and other fields, and related chemical companies will usher in new opportunities for transformation and development.
“Under the ‘double carbon’ goal, the two main carbon emission fields of energy and industry have greater demand for new materials.” Xu Lianghua, a professor at Beijing University of Chemical Technology, said that carbon fibercompositesIt can play a leading role in the fields of wind power, photovoltaic, nuclear energy equipment and industrial lightweighting, and has broad development prospects.
Chen Xinwei, President of the China Chemical Fiber Industry Association, believes that my country’s carbon fiber industry has gradually entered a stage of healthy development. Under the “dual carbon” goal, wind power, photovoltaic, hydrogen energy and other industries have developed rapidly, and the demand for carbon fiber is strong. The carbon fiber market The space is vast.
Data shows that the total global carbon fiber application volume has maintained growth for many consecutive years. In 2020, affected by the epidemic, it still achieved a growth rate of 3%, reaching 106,900 tons. my country’s carbon fiber market is growing strongly and showing prosperity. In 2019, the output exceeded 10,000 tons, and the total application volume was 37,800 tons; in 2020, the output was 18,000 tons, and the total application volume was 48,900 tons, a year-on-year increase of 29%. At present, the annual growth rate of my country’s total carbon fiber application has exceeded 20% for four consecutive years. In 2020, the domestic carbon fiber market accounted for 38%, a year-on-year increase of 6 percentage points.
Jilin Chemical Fiber Group was founded in 1960. It was originally a chemical fiber company that produced textile raw materials. In 2006, it decided to develop domestic carbon fiber through market research. Relying on its acrylic production technology experience and an innovative team composed of university experts, the company produced the first batch of carbon fiber upstream product precursors in 2007 through more than 70 technical improvements, equipment modifications and hundreds of repeated tests. In the second year, it obtained two national invention patents and developed into an important enterprise in the domestic carbon fiber industry.
In the past two years, driven by the two wheels of technology and market, Jilin Chemical Fiber Group has increased its carbon fiber research and development efforts and project construction progress, with an annual output of 15,000 tons of carbon fiber projects, 150,000 tons of carbon fiber raw silk projects, and 12,000 tons of carbon fiber projects. The carbon fiber composite material project and other 200,000-ton carbon fiber industry chain projects have started construction and reached production one after another, and the carbon fiber production capacity continues to increase. At the same time, Jilin Chemical Fiber Group continues to expand the research and development and manufacturing of carbon fiber composite products. The products have achieved application in aerospace, green electricity and new energy such as wind power and photovoltaics, lightweight automobiles, rail transit and other fields, building reinforcement, sports and leisure and other fields. cover.
Song Dewu, chairman of Jilin Chemical Fiber Group, believes that under the “dual carbon” goal, the development trend of new energy, lightweight, energy saving and consumption reduction will be stronger. It is expected that the demand for carbon fiber will show a blowout growth in the next three to five years.
In 2020, while the domestic carbon fiber market demand is strong, more than 60% of the supply will still come from imports. In order to make up for the domestic production gap, large-scale carbon fiber projects in Shanghai, Jilin, Qinghai and other provinces have started or been put into production since this year. Chen Xinwei believes that after nearly 20 years of development and accumulation, domestic carbon fiber technology has been able to play an important role in my country’s economic and social development.
Among the total global carbon fiber applications in 2020, wind power, aerospace, sports and leisure, and automotive fields accounted for 29%, 15%, 14%, and 12% respectively. Among my country’s total applications, the above four items accounted for 29%, 15%, 14%, and 12% respectively. Ratios are 40.9%, 3.5%, 29.1%, and 2%. Wei Huazhen, chief engineer of the No. 53 Research Institute of China Ordnance Industry Group, analyzed that comparing the two aspects, the development of new energy has a decisive impact on the carbon fiber industry. Automobiles and civil aviation will be the application markets for my country’s carbon fiber with significant growth.
In the energy field, the application of carbon fiber composite materials in the new energy field has been relatively popular, and the proportion of applications is constantly increasing through technological progress, and will be It has become the “ballast stone” that drives the rapid growth of carbon fiber demand. Song Dewu said that about 60% of Jilin Chemical Fiber Group’s carbon fiber production capacity this year is used in the wind power field, and most of the rest is used in the photovoltaic and hydrogen energy fields.
In the automotive field, whether it is a traditional fuel vehicle or a new energy vehicle, important components such as body, frame, transmission shaft, etc. are in urgent need of new materials to reduce weight and consumption. Carbon fiber is one of the best choices and is mainstream at home and abroad. Automakers are increasingly using carbon fiber composite materials in high-end new models. Data shows that the global carbon fiber application volume in the automotive field in 2020 will be 12,500 tons, nearly 18 times that in 2004, and is expected to increase to 18,300 tons by 2024.
In addition, more products using carbon fiber composite materials have been launched in important transportation equipment such as civil airliners, drones, high-speed rails, and subways. Wei Huazhen said that the future low-cost technological revolution will greatly increase the demand for carbon fiber in the transportation field.
�� Chen Xinwei believes that although the overall technical level of my country’s carbon fiber has entered the international advanced ranks, the maturity still needs to be further improved. Some key equipment, important raw materials and supporting materials, as well as testing and evaluation links are relatively weak, which has become an important factor hindering the development of my country’s carbon fiber industry. ; In the future, the carbon fiber industry should improve product quality consistency, batch stability, and application process, and expand its use in aerospace, new energy, rail transit, high-end equipment, automobiles and other fields Applications.
