Abstract

Single lap joint (SLJ) with the advantage of being lightweight has been utilized in composite structures. However, the crack usually initiates and extends before the unexpected failure in SLJ. If the crack could be detected in advance, the catastrophic failure can be prohibited. In this study, reduced graphene oxide (RGO) and epoxy were used as the adhesive for composite adherent single lap joint (SLJ). An electric field was applied to align the graphene in the adhesive along the thickness direction of the joint. The resistance variation of the single lap joint was measured in the monoclinic and cyclic tensile tests. The resistance variation during crack initiation and extension were measured, and the correspondence between the resistance variation and crack extension length were established.
