The invention discloses a continuous fiber thermoplastic composite plastic seat framework and a preparation method thereof. The seat framework is composed of a door-shaped groove rack and a support groove in the door-shaped groove rack, and the door-shaped groove rack is communicated with the support groove in the door-shaped groove rack to form a communicated groove. The preparation method includes that manufacturing an expanded view of the seat framework groove, and cutting a continuous fiber thermoplastic composite plastic sheet according to the expanded view shape; heating the sheared sheet; using at least one layer of heated sheet to cover a female die of the seat framework, wherein a groove of the female die is placed at the middle of the sheet; using a male die of the seat framework to press the sheet into the female die, and demoulding. The seat surface of the seat uses continuous fiber and long fiber, by means of the set, the arrangement and orientation of the fiber supplement each other, and the specific strength, specific modulus and impact resistance of the seat surface are greatly improved. A reinforcing rib uses long fiber, and the phenomenon that fiber is easy to break in the compression moulding process is avoided.
