Acoustic analysis of ballistic protective plates
Ballistic protective plates constitute an important element for the personal security of the Swiss Armed Forces. These are ceramic plates for the highest protection classes, which can experience a reduction in the intrinsic protective effect due to external influences, in addition to the actual ballistic impact, such as handling. Just dropping a plate can lead to fractures which considerably reduce ballistic protection, even if the defect is invisible to the naked eye. To ensure the safety of members of the Armed Forces, it is important to have a test procedure with which the condition of the protective plates can be assessed reliably and quickly.
