All industrial structures and components should be designed within the scope of their operation during their operation. However, sometimes the existing environmental and destructive factors can have devastating effects on the life and health of the desired structure or component. Some of these effects can include germination and crack growth in the structure, if these disadvantages emerge after the event, they will bear heavy and sometimes irreparable costs. To this end, structural health monitoring systems are used to predict and prevent the occurrence of these disadvantages. In this research, the analysis of the failure and health of composite repair bonding on a 2024-T3 aluminum plate under the influence of fatigue load has been addressed. In this research, the wave propagation technique has been extracted from the behavior of a restored structural structure with a composite patch that is not damaged. Then possible damage between composite repair and aluminum structure is applied, and again using the wave propagation technique, the structural behavior of the fault is analyzed and compared with each other. Also, the characteristics of the Lamb wave are extracted from the finite element model of restored structure under the influence of fatigue load and compared with experimental results. The analysis of these results, the connection of composite repair and the effect of failure in lamb wave characteristics are investigated. To carry out this study, the standard aluminum billet samples were prepared after the contact surface preparation using patches made of glass/epoxy composites and unilaterally repaired and alternated, and then piezoelectric sensors were mounted on the samples and went under load.
