<p><P>PROBLEM TO BE SOLVED: To provide a method and a means for efficiently performing especially a flame-resisting treatment for improving productivity of carbon fibers. <P>SOLUTION: The carbon fiber precursor fiber comprises: 100 pts.wt. of a polyacrylonitrile polymer and 0.01-5 pts.wt. of a carbon material having a microwave absorbing efficiency higher than that of the polyacrylonitrile polymer; and a relative dielectric constant [εr] of not less than 5 as an additive. The additive is preferably one or more substances selected from the group consisting of activated carbon, carbon nanotube (CNT), carbon nanofiber, fullerene, carbon black, graphite, silicon carbide, pitch coke, diamond, and diamond-like carbon. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
