In recent years, the Chinese government has successively issued a series of favorable policies to promote the development of the wind power industry, and has achieved good results. The newly installed capacity has ranked first in the world for ten consecutive years.

As a new material with excellent mechanical properties, carbon fiber not only has the inherent characteristics of carbon material, but also has the soft and processability of textile fiber. It is a new generation of reinforcing fiber, and its composite material performance is also at a higher level. As a subdivision of carbon fiber composite materials, resin-based composite materials have the advantages of low density, light weight, high strength, high modulus, fatigue resistance, long life, low thermal expansion coefficient, and good chemical corrosion resistance. The product application range The most extensive, mainly concentrated in many high-tech fields such as wind power blades, aerospace, automobiles, rail transit, electronic appliances and so on.

Carbon fiber composite material is a structural material made of carbon fiber and resin, metal, ceramic and other matrix composites. According to the different matrix, it can be subdivided into resin-based carbon fiber composite material, ceramic carbon fiber composite material, metal carbon fiber composite material, concrete and other carbon fiber composite materials. material. In 2019, the global carbon fiber composite material industry market size exceeded 21 billion U.S. dollars, of which the resin-based carbon fiber composite material market size was approximately 17.23 billion U.S. dollars, occupying the largest market share of the carbon fiber composite material industry, close to 80%.

According to the "In-depth Investigation and Analysis Report on the Market Supply and Demand of the Resin Matrix Composites Industry and Industry Operation Indicators for 2020-2024" issued by the New Sijie Industry Research Center, in recent years, with the continuous development of downstream industries such as wind power, aerospace, and automobiles , The application demand of resin-based carbon fiber composite materials has been continuously expanded. From the perspective of demand, from 83,000 tons in 2014 to 2019, the global demand for resin-based carbon fiber composite materials reached about 161,000 tons, with an average annual compound growth rate of approximately 14.2%. Among them, wind power blades and aerospace application demand accounted for the largest proportion, with 41,000 tons and 35,000 tons respectively, which together accounted for more than 45.0% of the total output.

From the perspective of downstream applications, taking wind power blades as an example, as countries around the world pay more and more attention to issues such as energy security, ecological environment, and climate change, the development of the wind power industry has become a universal consensus on promoting energy transformation and development and coping with global climate change. And act in concert. Of course, our country is no exception. In recent years, the Chinese government has successively issued a series of favorable policies to promote the development of the wind power industry, and has achieved good results. The newly installed capacity has ranked first in the world for ten consecutive years. Wind turbine blades are necessary equipment for wind turbine operation. With the rapid development of my country's wind power industry, its market development potential is huge. As the main raw material of wind turbine blades, resin-based carbon fiber composite materials are expected to achieve rapid development under this background.

Industry analysts from Xinsijie said that in recent years, resin-based composite materials have been widely used in the market due to their advantages of low density, light weight, high strength, high modulus, fatigue resistance, and good chemical corrosion resistance. Mainly concentrated in wind power blade manufacturing, aerospace, automobile manufacturing and other fields. With the continuous and stable development of these downstream industries, the application demand for resin-based carbon fiber composite materials continues to expand, and the future development space is broad.
