Abstract
Provided are carbon fibers which have a thicker single fiber fineness of the polyacrylonitrile-based precursor fiber bundles and lower production costs, and which have excellent mechanical properties. Also provided are: carbon fiber bundles having a single fiber fineness of 0.8-2.1 dtex, a strand strength of 4.9 GPa or greater, and a strand elastic modulus of 200 GPa or greater; carbon fiber bundles having a single fiber fineness of 0.8-2.5 dtex, a strand strength of 3.0 GPa or greater, and a strand elastic modulus of 240 GPa or greater; and an optimal method for producing said carbon fiber bundles. carbon fiber bundles having a single fiber fineness of 0.8-2.5 dtex, a strand strength of 3.0 GPa or greater, and a strand elastic modulus of 240 GPa or greater; and an optimal method for producing said carbon fiber bundles.
