| This paper reports the experimental results of a study investigating the effect of CFRP strengthening of metallic structures for increasing fatigue life. In the study, samples made form puddled steel and mild S235 grade steel strengthened with CFRP strips were examined. Samples were subjected to tensile fatigue loading with a stress ratio R of 0.115 and 0.130 (mild steel samples) and 0.13/1.25/0.15/1.07 (puddled steel samples). A total of 9 samples with CFRP/steel single overlap joints and 20 reference specimens were tested to determine their fatigue life and failure modes. Normal modulus CFRP strips with one cross section (20 x 1.4 mm) were used in this study. Laboratory test results showed that CFRP strengthening has visible effect on the fatigue life of the steel. The application of adhesively bonded CFRP laminates significantly prolongs fatigue life of the specimens. The increase in fatigue life of the steel samples strengthened with CFRP strips was 2 to 16 times (for mild steel) and 11.6 to 34.8 times (for puddled steel). |
