Problem. In the past , many ballistic protection devices have been constructed with high strength materials such as aramid fibers, plastics, and other materials of relatively complex chemical makeup . One drawback of using these materials is their relative instability over their use life due to exposure to changing and various ambient conditions such as high humidity, high moisture , temperature fluctuation and solar exposure. Changes in material properties as a result of these conditions have the potential of reducing effectiveness .
Description. A personal ballistic protection device incorporates multiple removable test coupons . Each of the test coupons are retained with the ballistic device during its use until each coupon is removed for test purposes . Each test coupon has a construction identical to the protective portions of the ballistic device and is removable and configured to allow for destructive testing . Sufficient coupons are provided with the ballistic protection device to allow for periodic testing over a predetermined useful life of the ballistic protection device One embodiment of the device is a body armor vest.
