This work is focused on the study of the evolution of damage mode and failure  mechanisms of woven composite bolted assembly carbon fiber/epoxy. In the present paper three configurations are studied [0°,45°,0°,45°], [0°,45°,0°,45°]s and [0°,45°,0°,45,0°]s. In order to analyze a global mechanical behavior of the assembly, monotonous tensile tests are performed. The damage evolution is followed simultaneously by acoustic emission (A.E) and digital image correlation (D.I.C). Acoustic signatures of four modes of damage are identified, matrix cracking, fiber-matrix debonding, delaminating and fiber breakage, then confirmed by microscopic observations in scanning electron microscopy (SEM). Keywords : woven composite- acoustic emission- bolted assembly- digital image correlation- damage. Analyse experimentale des mecanismes de rupture par emission acoustique des assemblages boulonnes en composite tisse Ce travail etudie l'evolution des modes d’endommagement et les mecanismes de rupture d’un assemblage boulonnee en composite tissee fibre de carbone/epoxy.  Trois types de configurations sont etudiees : [0°,45°,0°,45°], [0°,45°,0°,45°]s et [0°,45°,0°,45°,0°]s. Afin d’analyser le comportement mecanique globale de l’assemblage, des essais de traction monotone sont effectuees. L'evolution de l'endommagement est suivie simultanement par emission acoustique (A.E) et par la correlation d'image numerique (D.I.C). Les signatures acoustiques des quatre  modes d’endommagement sont identifiees a savoir la fissuration matricielle, la decohesion fibre-matrice, le delaminage et enfin la rupture des fibres puis confirmees par des observations microscopiques au microscope electronique a balayage (MEB). Mots-cles : composite woven, emission acoustique, assemblage boulonne,  correlation d'image numerique, endommagement.
