Pitch-based carbon fiber and process for preparation thereof |
| abstract |
A pitch-based carbon fiber having a microstructure consisting of strip-like structural units extended in the longitudinal direction of the fiber, wherein the fractal dimension D of the arrangement of the strip-like structural units in the cross-section of the fiber has a fractal structure satisfying the requirement of the following formula (2) relatively to the observation scale r satisfying the requirement of the following formula (1) with respect to the cross-section of the fiber: nE/2.5 > r > E/25 (1) n2.0 > D > 1.05 (2) nwherein E in the formula (1) stands for a smallest principal radius of gyration of cross-sectional area of the cross-section of the fiber. |
