Abstract:Broken hold of the skin is one of the most typical forms of aircraft battle damage. At present, the repair methods mainly include rivet repair and adhesive repair, which are insufficient in repair effect or repair time. In this paper, a method of adhesive-rivet hybrid repair was proposed to the skin broken hole. The fatigue test and finite element analysis were used to compare the fatigue properties of four kinds of specimens with prefabricated circular broken hole damage:without repair, riveting repair, adhesive repair and adhesive-rivet hybrid repair. The results showed that compared with the other two repair methods, the adhesive-rivet hybrid repair method has the best repair effect, and the fatigue life is 2.396 times that of the specimen with broken hole; The rivet function in the hybrid connection could effectively improve the bearing capacity of the adhesive layer and inhibit the peeling of the adhesive layer. Compared with the adhesive repair, the peak shear stress of the adhesive layer was increased by 6.3%, and the peak peeling stress was reduced by 23.1%. The adhesive-rivet hybrid repair method has better fatigue performance than riveting repair, and the repair time is shorter than that of gluing repair. It has a good application prospect in the battle damage repair of metal skin perforated structures.
