Abstract
A spinnable pitch was developed from the tetrahydrofuran-soluble fractions (THFS) of hyper coal (HPC)and used to prepare carbon fibers. THFS-derived pitch from bituminous coal-derived HPC showedexcellent spinnability and the obtained carbon fibers had a tensile strength of over 800 MPa with adiameter of 13 mm following heat treatment at 800 8C for 5 min. Thus, HPC was shown to be a usefulalternative precursor for the preparation of low-cost and general-performance carbon fibers.
