A Study on the Spinning Process of Pitches from Petroleum Residues for Manufacturing Carbon Fiber

In the paper, the spinning parameters of pitches from petroleum residues for manufacturing carbon fiber is investigated. The effects of the spinning temperature, pressure, speed and the pitch's structures and properties to spinning quality are discussed. The method of choosing the best spinning temperature with controlling melt viscosity at about 10 Pa·s, and the ability of enhancing the pitch's spinnability with raising spinning pressure are suggested.
