ABSTRACT:
The invention provides a method of making a fiber ply for forming a preform of a composite part in the form of a body of revolution having a non-developable surface, the method being characterized in that it comprises the steps consisting in:defining an annular space (23) with first and second canvases (20, 21) respectively defining an inner periphery and an outer periphery thereof;placing fibers between the canvases (20, 21) by placing the fibers in the annular space in at least one direction and by holding said fibers on the canvases by stitching;implementing circular connection stitching in the vicinity of the inner periphery of the annular space (23); andcutting out the fiber ply as made in this way in the annular space (23) in order to extract it from the canvases.
