The invention discloses an amorphous alloy wire modified badminton racket shaft and a preparation method thereof. The method comprises the following steps: weaving carbon fiber dipped with epoxy resin and an amorphous alloy wire into cloth, and leaving the cloth for 24 to 48h to stand; clipping and performing crimping forming on the cloth, putting the cloth into a badminton racket shaft forming mold, ensuring that the cloth is subjected to solidification forming in a 120 to 130 DEG C heating condition, and taking out the formed badminton racket shaft after the badminton racket shaft is cooled. According to the method, the amorphous alloy wire and the carbon fiber dipped with epoxy resin are woven in a mixed way, so that a novel composite material is formed, the material can enhance the strength and the elastic energy storage of the badminton racket shaft by greater than 30 percent when being used for manufacturing the badminton racket shaft; meanwhile, a balance point of a racket can be adjusted by adjusting the proportion of the amorphous alloy wire in the cloth and the position of the cloth laid in the forming mold, and the batting effect is enhanced.
