     delamination of the composite structural members is one of the prevalent damage modes which can grow among the layers of composite materials and decreases the performance of the member considerably. in this paper, an existing delaminated region will be assigned for two type composite beams and propagation of the predefined delamination will be examined during the fatigue loading. the delamination growth in the components was characterized for the defective beams in comparison with the perfect models. then using frp jackets, the delaminated region was wrapped regarding the predefined configuration of the composite jacket. then influence of the applied repair on the increase of fatigue delamination growth life was presented in comparison with the un-repaired models. delamination propagation of the models was performed using mvcct. these results provided useful guidelines for design engineers to apply the proposed repair technique for delaminated members under various fatigue loading conditions.
