On December 9, the Hay Think team was at SDYH`s high thermal conductivity carbon fiber and composite material industrialization project site. The world’s 4th and China`s first high-performance mesophase pitch-based carbon fiber aerospace-grade production line is running efficiently and continuously producing A silky finished product that is thinner than a hair. The asphalt-based carbon fiber will be widely used in cutting-edge technology fields such as aerospace, nuclear industry, rail transit, and electronic information.
As a major provincial project in 2020, the high thermal conductivity carbon fiber and composite material industrialization project invested by SDYH is a comprehensive park integrating the research and development, production, sales and production of high-performance mesophase pitch-based carbon fiber, and the establishment of carbon fiber industry technology research hospital.
High-performance mesophase pitch-based carbon fiber is an important material for aerospace and high-end equipment. After more than 10 years of cooperation with the Institute of Carbon Fiber and Composites, Beijing University of Chemical Technology, in 2018, SDYH finally passed the last step from R&D to application. Standard “threshold”, the carbon fiber joint R&D center was formally established. Its original polymerization, continuous high-efficiency spinning and continuous pre-oxidation, carbonization, and graphitization technologies, and self-developed production equipment, make high-performance mesophase pitch-based carbon fibers available in batches Production capacity.
"High-performance mesophase pitch-based carbon fiber is characterized by high modulus, high thermal conductivity, light weight, corrosion resistance, etc., which can replace many traditional materials and has a wide range of applications." SDYH General Manager Wang Xiangdong told Hay Think, mobile phone heating and heat conduction line It is directly related to the use of carbon fiber materials, and the heat can be quickly discharged; high-speed rail and aircraft brake modules also have extremely high requirements for heat dissipation. Carbon fiber materials can maximize heat conduction requirements and are durable and not deformed.
"From the extraction of raw materials to the production of composite materials, SDYH has formed an industrial chain around high-performance mesophase pitch-based carbon fibers. By 2025, SDYH can achieve an annual output value of 2 billion yuan of pitch-based carbon fibers and composite materials.
