Abstract
A method for manufacturing a fibrous preform for a blade or propeller part of a turbomachine, includes at least one fixing base extended by a mounting portion of an aerodynamic profile, the method including the winding of a fibrous texture, obtained by contour weaving, on a substrate of changing section having at least a first region of extra thickness in the shape of the fixing base and a second region in the shape of the mounting portion of the aerodynamic profile.

A method for manufacturing a fibrous preform for a blade or propeller part of a turbomachine, the fibrous preform comprising at least one fixing base extended by a mounting portion of an aerodynamic profile, the method comprising:
- winding a fibrous texture, obtained by contour weaving, on a substrate of changing section having at least a first region of extra thickness in a shape of the fixing base and a second region in a shape of the mounting portion of the aerodynamic profile, wherein the substrate has the shape of the preform to be obtained and wherein the fibrous texture matches the shape of the substrate during the winding without being deformed.
