Özet

The objective of this study is to investigate the impact behavior of laminated glass/epoxy composite plates with [0/90/0/90](S) and [0/90/45/-45](S) stacking sequences at room (approximate to 20 degrees C) and high temperatures (60 degrees C and 100 degrees C). The maximum contact force between the impactor and the composite plate, the maximum deflection at the maximum contact force at the center of the composite, and the contact time history were plotted as a function of impact energy. In order to determine the energy absorbing capability of the plates, energy profiling method was used. The results show that the perforation threshold increases with increasing temperature.
