The present invention relates to a method for producing a part made of a composite material, comprising a step of producing a needled preform (105) which comprises at least two needled sub-sets (103a) of plies stacked one on top of the other, each needled sub-set of plies being obtained by needling non-woven filaments applied to at least a first main face of a sub-set of superimposed plies (101a), wherein each ply is formed of continuous fibres, the needling being performed by a needling device (7) comprising a plurality of needles (71), each needle being provided with a notch, such that filaments are carried by the needles and arranged in a direction that is substantially perpendicular to the continuous fibres of the sub-set of plies, and a step of treating the needled preform to form the polymer matrix of the part made of composite material.
