description In view of the problem of poor interfacial cohesiveness between aramid fibers and epoxy resin, the invention provides a method for modifying aramid fibers with multi-walled carbon nanotubes, and is characterized in that the method is used for graft modification of the aramid fibers with the multi-walled carbon nanotubes. The concentration of a H2SO3CL/CH2CL2 solution is 0.2 wt%, and the concentration of a chloroform solution of the multi-walled carbon nanotubes is 0.1 wt%. The method comprises the steps: adding the multi-walled carbon nanotubes into a modified solution, stirring, carrying outultrasonic dispersion, washing cleanly and drying; and removing impurities on the surface of the aramid fibers by ethanol, then drying, treating with the H2SO3CL/CH2CL2 solution, stirring in deionizedwater and drying; and carrying out graft modification of the treated aramid fibers in the chloroform solution of the multi-walled carbon nanotubes. The strength of the modified aramid fibers preparedby the method is enhanced
