The invention discloses an integrally-formed three-dimensional weaving composite rotor wing blade and a manufacturing method thereof. The blade mainly consists of main parts of a root connecting joint, a blade up and down wing surface skin and a bearing main beam. The overall structure of the blade adopts is integrally formed by carbon fibers through a three-dimensional weaving process, and is integrally cured through an RTM process so as to finish blade processing. Compared with the conventional laminated composite blade, the blade in the scheme does not need secondary cementing and machining, the continuity of the bearing fiber inside the blade structure is ensured, the bearing efficiency of the structure is improved, meanwhile, the advantages of the three-dimensional weaving composite are fully played, the problems of lamination and cementing failures of the laminated composite are avoided, and the fatigue property and damage tolerance of the blade are improved.
