The invention relates to a method for assembling a first metal part with a second part made of a composite material comprising at least one matrix and fibers arranged inside the matrix. The method comprises at least:



a step of forming the first part, consisting in producing a plurality of teeth projecting from a contact face of the first part, two adjacent teeth being separated from each other by an interstitial space, the teeth having an end protuberance; and
a step of pressing the second part against the first part,

in such a way that the fibers of the composite material can penetrate inside the interstitial space defined between adjacent teeth and that the fibers are retained by the end protuberances of the teeth.
