Abstract: The present invention relates to a link arm for connecting a first unsuspended mass to a second suspended mass, and its manufacturing method. The invention applies in particular to a suspension system for a motor vehicle, wherein the arm is able to equip a wheel suspension by having triangular housings to receive a stub axle of the wheel and two connecting links to the chassis of the vehicle. This arm (1) comprises housings (14, 15, 16) to receive a first linkage joint (14a) to the first mass, and at least a second linkage joint (15, 16) to the second mass, and comprises: a stiffening portion (2) which comprises a first thermoplastic or thermosetting matrix composite material reinforced with fibers and which comprises a peripheral rim (8) of the arm, and an anti-buckling portion (3) interposed in the stiffening portion and extending from the rim over substantially the entire arm. According to the invention, the fibers are continuous and united in the form of a main skein of first fibers extending along the rim, which encloses the anti-buckling portion.
