This paper first introduces the structure and properties of carbon nanotubes

and then points out the advantages and disadvantages of carbon nanotubes. Carbon nanotubes

as a novel one-dimensional nanomaterial of carbon structure

have excellent optical

electrical

mechanical and thermal properties. However

the surface of the carbon nanotube lacks active groups

poor dispersion

and is difficult to process

which limits its application. Then the types and properties of aramid fiber are introduced

and the mechanism of modification of carbon nanotubes by aramid fiber is introduced. Three physical methods and a chemical method for modifying carbon nanotubes by aramid fiber are reviewed. The performance of the new materials obtained was also analyzed. Finally

the development of fiber and carbon nanotube composites is prospected.
