In this study, we investigated the fatigue characteristics of silane-treated aluminum/CFRP composite material. Three different specimens of cracked aluminum, cracked aluminum repaired with CFRP patch, and silane-treated aluminum repaired with CFRP patch were used in the fatigue tests. Load ratio and the frequency applied in the fatigue tests were 0 and 10 Hz, respectively. The results showed that the specimen repaired by composite patch showed three times more improved fatigue life than aluminum specimen. Furthermore, the silane-treated specimen repaired by composite patch showed four times more improved fatigue life than the non-treated specimen.
