Domestic coal-based general-grade pitch-based carbon fiber technology progresses and the industry is entering the pilot stage

pitch-based carbon fiber refers to a type of carbon fiber prepared from materials rich in condensed aromatic hydrocarbons such as pitch, through polymerization, spinning, infusibility, and carbonization. according to the difference in properties, pitch-based carbon fiber can be divided into general-purpose pitch-based carbon fiber and high-performance pitch-based carbon fiber. according to the composition of raw…
