“…This result is supported by previous similar studies. According to Zonghong et al 14 scarfed the samples produced from carbon fiber fabric prepreg at 2°, 4°, and 6° angles and used external plies for repair. As a result of the study, it was observed that the failure strength value of the 2° scarf repaired sample was higher than the others.…”

Today, composite materials, which have the advantage of strength and lightness ratio, have gained great importance especially in the aeronautical industry and automotive sector. With widespread use of composites, the repair of damages caused by external factors has also become an important research topic. In this study, the effects of different repair methods and scarf angles on the mechanical performance of the material were investigated. Scarf angles of 20°, 30°, and 45° have been selected in order not to create too many scarf areas and to find a quick repair method. Also, a comparison of single scarf and double scarf repair was made to find a more robust solution. The samples were produced from carbon fiber prepreg and with the [45/0/90/0/45]2s fiber orientation. Tensile, compression, and flexural (3-point bending) tests according to ASTM standards were applied to composite samples prepared with single scarf and double scarf repair configurations at different angles. The stress–strain curves obtained as a result of the tests showed that the specimens repaired at 20° had the highest strength. In addition, it has been determined that the samples repaired with double scarf withstand higher forces compared to the samples repaired with single scarf at the same angle.

“…Therefore, adhesively bonded single scarf with 20°seems to be more suitable solution for a quick and durable but also reliable repair, as it is easy to apply and also does not need to create a large scarf area as compared with previous low scarf angle studies in the literature. 5,11,13,[14][15][16]…”
