Carbon felt (CF) has a wide range of applications and my country’s research has made new progress

Carbon felt (CF), also known as carbon fiber felt, refers to a composite material made of carbon fiber. Carbon felt has the excellent properties of both carbon materials and carbon fibers, including good chemical stability, high strength, good electrical conductivity, lightweight, corrosion resistance, etc. It is widely used in aerospace, sports equipment, petrochemicals, automobile manufacturing, batteries and other fields .

Polyacrylonitrile (PAN)-based carbon felt is the mainstream product of carbon felt, which can be subdivided into PAN-based raw silk carbon felt, PAN-based acrylic carbon felt, PAN-based pre-oxidized fiber carbon felt, etc. PAN-based raw silk carbon felt has the advantages of good oxidation resistance and low production cost, but it consumes a lot of energy and has a complicated production process. PAN-based acrylic carbon felt is a mid-to-low-end carbon felt with a wide range of applications. There are many manufacturers in my country ; PAN-based pre-oxidized wire carbon felt has the advantages of good thermal insulation, good elasticity, and low ash content. It is a high-end product in the carbon felt market, but its operating cost is high and its market share is low.

According to the “2023-2028 China Carbon Felt (CF) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that carbon felt is widely used in aerospace, sports equipment, petrochemical industry, automobile manufacturing, batteries and other fields. In the field of aerospace, carbon felt can be used to make structural parts of aircraft and rockets; in the field of sports equipment, carbon felt can be used to produce bicycle frames, golf clubs, tennis rackets, etc.; in the field of automobile manufacturing, carbon felt can be used to make cars. Engine hood, suspension, body and chassis, etc.; in the battery field, carbon felt can be used to produce proton exchange membrane hydrogen fuel cells.

In recent years, my country’s carbon felt research and development enthusiasm has been high and many new developments have been made. In 2022, Liu Tao’s research team at the Dalian Institute of Physics and Chemistry successfully prepared an all-vanadium redox flow battery carbon felt electrode using pitch-based carbon fiber and PAN-based carbon fiber. In the future, with in-depth research and technological advancement, carbon felt will be widely used in the field of energy storage.

Liaoyuan Tianxiang Carbon Fiber Material Co., Ltd., Gansu Fulai Carbon Fiber Technology Co., Ltd., Liaoning Xinde New Material Technology Co., Ltd., Shenyang Yuheng Carbon Fiber Co., Ltd., Hunan Jinbo Carbon Co., Ltd., Jilin Shenzhou Carbon Fiber Co., Ltd., etc. are my country’s Major producers of carbon felt. At present, my country’s carbon felt market is dominated by small and medium-sized enterprises, lacking leading competitive companies, and the industry concentration is low. In the future, as downstream demand grows and technology levels improve, companies with independent research and development capabilities for high-performance carbon felt will occupy a larger space in the Chinese market.

Industry analysts said that as a new composite material, carbon felt has the advantages of high strength, good conductivity, and lightweight. It is widely used in many industries. Wide range of applications. In recent years, my country’s carbon felt research enthusiasm has been high and many new developments have been made. It is expected that the application scope of my country’s carbon felt will be further expanded in the future. In terms of market competition, my country’s carbon felt industry has a low degree of concentration. The market is dominated by small and medium-sized enterprises and lacks leading companies.
