A finite element model of scarf repaired laminates in tension is built in this paper. The ultimate strengths of the repaired structures are calculated with progressive damage analysis method. The predicted results agreeing well with the experimental results which means the model is effective. The failure model of these structures is adhesive failure which is obtained by analyzing the failure process of these structures. The effects of scarf ratio and scarf depth on the ultimate strength are analyzed which indicates that the ultimate strength can be improved by both decreasing scarf ratio and decreasing scarf depth .The results of this study can provide some references for the design of scarf repaired composite laminates.
