Investigation of Low Velocity Transverse Impact Behavior of Metal Laminated Composites

In this study, transverse impact behavior of laminated metal composites was investigated. Four different configuration namely (Al)3, (St)3, (Al+St+Al) and (St+Al+St), were made by using St37 DKP and 1050-H14 Al alloy which all in 1 mm thick. Three layered composites were tested under various impact energies. The panels were cut in 150x150 mm dimensions and they were restricted from their four sides. Impactor that used in tests has mass of 6.35 kg and it has 24 mm semispherical tip. Each configuration was impacted 10 J, 20 J, 30 J, 40 J and 50 J. Retrieved data from the tests were investigatedin forms of force-time, velocity-time and force-displacement. Finally, failures were evaluated for each test.
