Abstract

The method consists in realizing densified layers of fibers, in forming a stack with said layers of fibers provided with holes and so arranged that the fibers of the layers extend within the stack in at least two directions designated as first and second directions which define the plane of the layers and that the holes form passages within the stack in a third direction, in implanting in said passages fibers which extend in the third direction, and in increasing the density of the assembly, for example by filling the gaps of the structure with a resin or a carbon matrix.
