The Manufacture of Pitch-Base Carbon Fibres

Making carbon fibres from low-cost petroleum pitch is the most attractive mcthod to produce commercial carbon fibres.
Isotropic carbonaceous pitch-base continuous and short carbon fibres have made successfully at both laboratory and pilot plant. The pretreatment of petroleum sludge to make precursor, the spinning process, infusibiliza tio n and carbonization treatment are described. The tensile strength of carbon fibres is about 686.5 MPa.
