Abstract

Abstract: In this study, the mechanical behaviours of adhesively bonded composite joints were investigated applying different mechanical tests such as vibration and axial impacts. In the first step of this study, the vibration tests were applied to adhesively bonded composite plates with different cycles (1.5 × 10 5, 3 × 10 5, 12 × 10 5 and 24 × 10 5 ) via vibration motor. After the vibration tests, as a second step of the study, these plates were cut as a single lap adhesively bonded composite joints and axial impact tests with different impact energy values as 5, 10, 15 and 20 Joules were applied to these joints. Subsequently, quasi-static tensile tests were implemented to adhesively bonded composite joints. According to experimental results, the strength of adhesively bonded composite joints decreased with the increasing of axial impact energy and vibration cycles. The experimental results showed that the strength was higher only at 10 J energy when compared to other impact energy values.
