With the extensive application of advanced composite materials on civil aircraft, it is particularly important to study the repair technology of composite structures. The bonding scarf patch repair of laminate plate is a kind of mature repair method. Among them，the bonding inclined surface scarf patch repair method is simple and widely used in civil aircraft. It can be used to repair defects such as delamination, debonding and superfluous holes of parts with damage range less than 15%. Static strength calculation method is generally used in engineering to evaluate the strength performance of repaired parts. The repair and strength calculation of composite laminate part have been carried out and the results show that the repair and static strength evaluation method is feasible in engineering application.
