Abstract
A method for producing a composite material, includes: immersing a carbon fiber bundle, including continuous carbon fibers, in a dispersion in which carbon nanotubes are dispersed in water, alcohol, or organic solvent; applying a tensile force to the carbon fibers, which are linearly arranged, using flat rollers; moving the carbon fibers linearly, under the tensile force by the flat rollers, at a constant depth inside the dispersion at a traveling speed of 1 to 20 m/min, such that the carbon nanotubes in the dispersion are adhered to respective surfaces of the carbon fibers; and applying a sizing agent to cover at least a part of the respective surfaces.
