    Abstract

    While there is tremendous interest in the melt spinning of polyacrylonitrile (PAN) with presence of plasticizers, the behavior of plasticized PAN melt and the spinning process have not been adequately investigated so far. In this paper the melting and rheological behavior was studied for PAN plasticized with water or water and a second plasticizer. A lab scale pressurized fiber spinning system was developed and used to generate melt-spun fibers as carbon fiber precursors. The morphological and mechanical properties of the fibers were evaluated and compared with commercial wet-spun fibers. The melt- spun PAN fibers have surface and mechanical properties similar to those of commercial fibers.
