Response of laminated composites to the impact loading

The purpose of this thesis is the examination of damage and deformation of fiber reinforced laminated composites with varying stacking sequences under impact loading in order to figure out the best combination.Specimens were built in the Composite Research Laboratory at Dokuz Eylül University with vacuum infusion method. After the manufacturing process the thickness of the composite was measured as 2.2 mm and cut into as 100 x 100 mm dimensions. Specimens were placed inside the Fractovis Plus test machine to apply the impact loading with various impact energies.Conclusions were made according to Contact Force ? Time, Energy ? Time, Deflection ? Time, Contact Force ? Deflection graphs. Further, visual inspection was undertaken by photographs. Results indicated that fiber and ply orientation effects the resistance under impact loading.
