The present invention provides a carbon fiber reinforced polyamide/polyphenylene ether alloy material and a preparation method thereof, comprising: Step S1, putting 20–30 parts of polyphenylene ether resin, 0.2–1 part of antioxidant, 1–8 parts of compatibilizer, 2–15 parts of toughening agent and 0.3–1 part of lubricant into a high-speed mixer to obtain a granular-powder mixture; Step S2, adding the granular-powder mixture into a main feeding hopper of a twin-screw extruder; Step S3, adding the particles obtained in Step S2 and 50–70 parts of nylon resin into the twin-screw extruder from the main feeding hopper, adding 5–20 parts of chopped carbon fibers into the twin-screw extruder from a side feeding hopper, and extruding and pelletizing to obtain the carbon fiber reinforced polyamide/polyphenylene ether alloy material. Beneficial effects: improving the antistatic property and conductivity of the material, while having excellent mechanical strength, heat resistance, wear resistance and other characteristics; in addition, improving the mixing and extrusion process of PA/PPE alloy material, solving the problem of poor dispersion of PPE resin, and avoiding defects such as delamination, peeling and material spots.
