The invention discloses a three-dimensional braided composite material propeller blade of a ship and a manufacturing method thereof. A design of a core mode for supporting of a preform is conducted according to the requirement of marine power, and the design comprises determination of a blade main structure and specific strengthening part structures; according to the structure of the core mode and the strengthening design requirement, the category of a high performance fiber and a key characteristic of hybrid fiber yarn are determined, and the manufacturing of the hybrid fiber yarn is performed; the hybrid fiber yarn is adopted and the three-dimensional braided technology is applied to conduct continuous braiding forming of the propeller blade hybrid fiber preform; thermosetting resin adhesive glue solution is taken as a substrate, a vacuum infusion technology and a thermosetting process are adopted to conduct resin impregnation and vacuum solidification treatment on the hybrid fiber blade preform, and the three-dimensional braided propeller blade of the ship is obtained. The application of the three-dimensional braided structure and the combined process of the vacuum infusion and the thermosetting improve the strength of the propeller blade, and the production efficiency of the blade is effectively improved.
