The purpose of the Force Indicator for Ballistic Armor Vests is to obtain an approximate value for the impact a bullet delivers through a trauma pad after the Kevlar layer stops the initial bullet. This approximation will be applied in the field to assist in medical treatment of gunshot wounds. The indicator is made from a pressure-sensitive film located behind the Kevlar layer and trauma pad, and it can be easily removed in the field for examination. The impact vest and force indicator are self-contained for ease of implementation. The device will be tested with 9mm, .22 Long Rifle, and .357 Magnum ammunition to visualize the differences in impact pressure between different bullet calibers. This result will be used to create a device by which injuries resulting from the impact of a bullet can be predicted, as well as to verify this device’s functionality in testing.
