The invention discloses a three-dimensional braided composite material propeller blade for an airplane and a manufacturing method of the propeller blade. The preparation method comprises the following steps: designing the blade mold appearance, comprising the operation of designing the specific reinforcing parts of different strength and rigidity requirements; performing integral braiding on the blade main body and the specific reinforcing parts of the blades by adopting a carbon fiber three-dimensional preform multi-part combined braiding technology, thereby obtaining a three-dimensional braided structure; performing secondary suture reinforcement treatment along the thickness direction of the three-dimensional braided structure after the preparation of the three-dimensional braided structure is finished, thereby obtaining a secondary suture structure; by taking thermosetting resin glue liquid as a matrix, finishing the resin compounding process of the three-dimensional stereoscopic braided structure by adopting the process of combining vacuum infusion and rapid thermocuring, and finally, manufacturing the carbon fiber composite material propeller blade. By utilizing the multiple three-dimensional stereoscopic braided structures, the secondary suture technology and the process of combining vacuum infusion and rapid thermocuring, the strength of the propeller blade is enhanced, and the production efficiency of the blade is effectively improved.
