NOVELTY - Preparation of two-dimensional nano-material-based modified carbon fiber comprises condensing carbon fiber tow, refluxing in an acetone solution, cleaning with deionized water, and vacuum drying; dispersing the two-dimensional nanomaterial in water or organic solvent and stirring; and spreading the carbon fiber tows on filter membrane, vacuum depositing, turning at over 180degrees, vacuum filtering, and vacuum drying. USE - The method is used for preparing two-dimensional nano-material-based modified carbon fiber. ADVANTAGE - The method solves the problem of reduced fiber strength, complex process, difficult operation, environment pollution, and high processing cost. The modified carbon fiber improves interface bonding strength of the composite material by 12.3% to 75.5%.
