AUBE OU PALE D'HÉLICE AVEC PIED COMPOSITE ENROULÉ
The invention relates to a propeller blade or airfoil (10) for a turboprop engine, made from composite material and comprising a matrix-densified fibrous reinforcement, the propeller blade or airfoil comprising, in a longitudinal direction (DL), a root (12) and an aerodynamic profile (11). The fibrous reinforcement comprises a fibrous preform (200) having a three-dimensional weave with a root preform portion (121) present in the root (12) and an aerodynamic profile portion (211) present in the aerodynamic profile (11), the root (212) and aerodynamic profile (211) perform portions being joined to one another by the three-dimensional weave. The root preform portion (212) includes two woven skins (2121, 2122) wound around an insert (130).
