Thermal aging effect on the strength of single lap jointed composite plates

In this study, the thermal aging effect on failure loads of the single lap jointed composite plates was determined with experimental study. The composite plates were joined with different adhesive thickness 0,2 mm, 04 mm, 0,6 mm and these plates were exposed to the different temperature 75℃, 100℃, 150℃ and to the different times 2, 4, 6, 8 hour in an electrical oven. At the end of thermal aging process, these plates were loaded with axial tensile load. The failure load of thermally aged specimens results were compared to un-aged specimens results. As a result of these studies, the thermal aging effect on the strength of single lap joints was determined. According to the this study thermal aging effect increased the mekanic result of the single lap jointed composite plates. Best resullt of this study got from the 100℃ and 2 hours speciemens.
