Alumina (Al_2O_3) ceramic with the properties of good hardness, thermal shock resistance, and chemical corrosion resistant features as aluminum based ceramic plate is sandwiched by two layers of Kevlar composite plates. The multilayer composite plates manufactured were tested by low velocity impact testing machine and damage analysis was made. Minimum impact energy level and its fragment-velocity equivalent were studied to be determined. The data obtained through impact testing were finally verified by Ansys /Autodyne FE analysis.
