Abstract
A method of needling a fiber layer, includes first needling the fiber layer by a needling head, during which the fiber layer is caused to move in translation relative to the needling head, wherein needles of the needling head are distributed uniformly over a surface of the needling head; after the first needling, shifting the fiber layer relative to the needling head along a shift direction through a distance d equal to N·x·p, where N is an integer not less than 1, x is a coefficient greater than 0, and less than 1, and p designates the pitch of two consecutive needles of the needling head along the shift direction; and second needling the fiber layer, after the shifting, and during which the fiber layer is moved in translation relative to the needling head, the needles not penetrating, during the second needling, into the holes formed during the first needling.
