Effects of the surface form and aging to impact performance of the composite plates

In this study, it has been investigated that dynamic response of the aged composite of E-glass/epoxy layers under low-velocity impact with experimental. Single direction reinforced layers were put in order like to [55/55/0]s and 4 layers samples were obtained. Four different surface form samples were produced. The impact tests were conducted with a vertical drop weight testing machine. The impactor has 24 mm in diameter and its mass is 4.926 kg, and it has a geometric figure of a semi globe point. The impact speeds that tests were done with 4.58 m/s velocity and 20 j energy. In the studies, the samples that 100 mm x 100 mm dimensions and four different surface form had been tied to mould which have 100 mm diameters and were applied the impact tests. End of the experiments, It has been investigated absorbed energy, quantity of damage, power of contact and deformations.
