Abstract
A method of making a three-dimensional fiber preform for fabricating an annular part out of carbon-carbon composite material, the method including stacking layers of a fiber sheet made up of carbon yarns or tows, needling the layers one by one as they are superposed so as to bond them together, and locally modifying the electromagnetic properties of the fiber preform by increasing the fiber density of the layers of the fiber sheet that are situated at half-thickness of the fiber preform.
