Research on composite shields to protect vehicle crew from the effects of gunfire

The article deals with the problem of selection of materials for two-component armored shields of motor vehicles. It is indicated how the Florence model can be used for practical purposes in the design process of the vehicle protective system and reduce the number of material combinations in ballistic verification tests. The procedure in configuring the shield for the assumed “a priori” protective and mass properties relevant to vehicle mobility is discussed. The method of configuring the above-mentioned materials is presented on the example of two-component shields in the combination of ceramic substrate of aramid and ceramic substrate of polyethylene type UHMWP. The level of protection according to the Nato Stanag 4569 document and the surface density of the shield were assumed. The selected configurations were verified in ballistic tests by determining the value of the V50 parameter. This research confirmed the possibility of using the Florence model to design simple two-component shields and reduce the number of configurations in ballistic tests confirming the assumed protection level by determining the V50 parameter.
