Rotationally symmetrical part made of composite material having an improved holding capacity

Abstract

A method for manufacturing a composite material revolution part for a propulsion assembly includes making a fibrous preform on a mandrel having a profile corresponding to that of the part to be manufactured, and densifying the fibrous preform by a matrix. Making the fibrous preform includes forming a strip-shaped fibrous blank including at least one layer of continuous fibers and at least one layer of discontinuous fibers, the fibrous blank being shaped on the mandrel, the layer of continuous fibers of the fibrous blank extending at least over a complete turn around the mandrel.
