Abstract (en)
[origin: EP3279394A1] There are provided a method for producing a composite material (10) from which a high-strength prepreg having CNT-derived properties fully exerted is obtained, comprising a step of immersing a carbon fiber bundle (12) including a plurality of continuous carbon fibers (12a) in a carbon-nanotubes-isolated dispersion containing a plurality of isolatedly-dispersed carbon nanotubes (14a) and applying ultrasonic vibrations at a frequency of more than 40 kHz and 180 kHz or less to form a structure comprising a plurality of carbon nanotubes (14a) on the surface of each of the plurality of carbon fibers (12a), wherein the structures are directly attached to the surface of each of the plurality of carbon fibers (12a) and form together a network structure in which the carbon nanotubes (14a) are directly connected to one another, and such a composite material (10) .
