The invention discloses a manufacturing method of a carbon fibre hub. The manufacturing method is characterized in that the manufacturing method comprises the following steps of preparing a special mould, wherein the special mould comprises an upper mould as well as a lower model and at least three side moulds; selecting a straight-form nylon air pipe the diameter of which is greater than that of a cavity of the carbon fibre hub to be manufactured, sealing the two ends of the straight-form nylon air pipe through a sealing joint strip, and ensuring a plastic guide pipe to be fixed at one end of the straight-form nylon air pipe, wherein the plastic guide pipe passes through a nylon air pipe port to ensure the straight-form nylon air pipe to be communicated with atmosphere, and the two sealing ends of the straight-form nylon air pipe are connected through same standard nylon sleeves; and paving layers and assembling dies, thus finishing the manufacture of the carbon fibre hub through a vacuum infusion method after. According to the invention, the pressure required by the nylon air pipe can not be considered, and due to the layer paving design, the problems that resin rather than fiber only exists at the hub part caused by shortage of the shape of the nylon air pipe, defects caused by fast flowing of the resin due to a gap between the fiber cloth and the mould, and the like, can be obviously improved..
