主　　题：Low Velocity Impact E-Glass/Epoxy Composite Buckling 

摘      要：The work described herein consists of experimental measurement of the post-impact buckling loads of E- glass/epoxy laminates. Composite samples with stacking sequence of [+45/?45/90/0]2s were subjected to low-velocity impact loading at energy levels of 36, 56.13, 79.95, 110.31 and 144 J. The impact tests were conducted with a specially developed vertical drop weight testing machine. Impact parameters like peak load, absorbed energy, deflection at peak load and damage area were evaluated and compared. Damaged specimens were subjected to compressive axial forces and buckling loads of the specimens were obtained. The relation between energy levels and buckling loads is investigated.
