Özet

The postimpact buckling loads of E-glass/epoxy laminates have been measured. Composite samples with the stacking sequence [+45/-45/90/0] 2s were subjected to low-speed impact loadings at various energy levels. The tests were conducted on a specially developed vertical drop-weight testing machine. The main impact parameters, such as the peak load, absorbed energy, deflection at the peak load, and dam age area, were evaluated and compared. The damaged specimens were subjected to compressive axial forces, and their buckling loads were determined. The relation between the level of impact energy and buckling loads is investigated. © 2009 Springer Science+Business Media, Inc.
