In this research, CFRP scarf repair panels were tested to evaluate the tensile mechanical properties and impact characteristics. CFRP scarf repair panels were prepared to simulate the assumed three different situations. These situations consist of two different scarf repair methods and impact damage case which are autoclave repair, heat blanket repair, and impact damage case. As the result, these strengths are not recovered in all situations, however, stiffness was recovered in all situations. Moreover, the strength of heat blanket repair and impact damage case were reduced compared with autoclave repair.
