Carbon fiber material, carbon fiber material manufacturing method, and material containing the carbon fiber material

摘要

The object of the present invention is to provide carbon fiber material having high electrical conductivity at a low cost. A manufacturing method of carbon fiber material comprises a dispersion liquid preparation step, a centrifugal spinning step and a denaturation step. The dispersion liquid preparation step is a step in which dispersion liquid containing resin and carbon particles is prepared. The centrifugal spinning step is a step in which nonwoven fabric made of a carbon fiber precursor is formed from the dispersion liquid. The denaturation step is a step in which the carbon fiber precursor denatures into carbon fiber.

主权项

1. A method of manufacturing a carbon fiber material, the method comprising:
centrifugally spinning a dispersion liquid comprising a resin, carbon particles, and a solvent, to obtain a nonwoven fabric comprising a carbon fiber precursor; and denaturing the nonwoven fiber comprising the carbon fiber precursor, to obtain a nonwoven fabric comprising carbon fiber having a large diameter part extending a first length and a second smaller diameter part extending a second length.
