Özet
In this study, the effect of humidity and temperature on glass fiber reinforced epoxy composite plates with different fiber reinforcement angles and different widths were experimentally investigated. For this purpose, composite plates with fiber reinforcement angles of [0°]8 and [45°/-45°/0°/90°]s were prepared in 25 mm and 30 mm dimensions and kept in hot water at 40 °C, 60 °C and 80 °C for 15, 30 and 45 days. At the end of the duration, the moisture absorption rates and strengths of the specimens were obtained. The obtained data were compared among themselves and with that of dry specimens. In addition, the morphologies of the specimens were visualized with the help of Scanning Electron Microscope (SEM) and the effects of humidity and temperature on failure behavior were examined. It was determined that the strength of the [45°/-45°/0°/90°]s fiber orientations specimens was lower than the strength values obtained from the [0°]8 fiber orientations specimens. It has been determined that when the waiting time and temperature increase, the matrix/fiber structure of the specimens deteriorates and the strength values decrease accordingly.
