Abstract
A method of fabricating a turbine engine blade out of composite material includes three-dimensionally weaving yarns to make a preform including root and airfoil portions that are connected together by oblique side faces for forming bearing surfaces enabling the root to bear against an assembly slot in a rotor disk. The method also includes compacting the preform in a mold having a cavity with first oblique side faces corresponding to the above-mentioned side faces of the preform, and second oblique side faces bearing against the root portion of the preform and at angles of inclination opposite to those of the first oblique side faces. Further, the method includes vacuum injecting a resin into the mold and polymerizing the resin.
