Abstract

Analytical models were developed for the analysis of adhesively tapered scarf joint repair subjected to unidirectional tension. Stiffness and strength of the joints were analyzed, and the corresponding analytical equations were presented. Extra plies on repair patch were also considered in the models. A series of specimens with different scarf angles and extra plies were designed to conduct corresponding experiments, as to observe scarf angles and extra pies' influence on the performance of the joints and to validate the results of the models' predictions. The results show that reducing scarf angle and adding extra plies help enhancing the stiffness and strength of the joints within a specified range of scarf angles. The predicted results present a good agreement with the test results. The relative errors of stiffness are less than 5%, while that of strength are not more than 14%. The proposed analytical models could provide an efficient and accurate tool for parametric study and design of adhesively tapered scarf joints.
