The invention discloses a manufacturing process of a carbon-fiber hub. The carbon-fiber hub is manufactured by a hollow compression molding process. The manufacturing process specifically includes thesteps of firstly, calculating strength needed to be borne by the hub and the fatigue resistance of the hub according to the mechanical performance and bearing strength needed by the hub; secondly, using a computer to perform 3D effect finite element analysis on the hub to learn about the conditions of loading force borne by various parts of the hub, maximally optimize the stacking structure of the hub, reduce unnecessary carbon fiber yarn layers and achieve good weight control; thirdly, using a PU foaming agent to manufacture a rolling pre-section mould; fifthly, cutting carbon-fiber pre-impregnation yarn according to the designed stacking structure, and rolling according to the stacking sequence; sixthly, placing a rolled pre-model into a mould cavity, and performing solidification underthe high-temperature of 1
