Abstract
In many cases the level of personal protection especially during transportation by personal motor vehicles is dependent on burglar resistance of used car body materials. Currently commercially manufactured personal motor vehicles are modified by insertion offiller materials of high density (steel plates inserted into doors, steel reinforcements of vehicle floors). This approach causes not only increase in financial costs for procurement of such modified (armoured) vehicle, but also changes its driving characteristics. Particularly its financial cost affects its accessibility to wide public. Several cases of use of small firearms against the occupants of commercially manufactured personal motor vehicles have been investigated in recent years. The results of such attacks were casualties or grievous bodily harm. Considered materials were experimentally tested for the purpose of increasing burglar resistance mainly of commercially manufactured motor vehicle doors and increase of their burglar resistance against shots from small firearms. The result of experiments that were carried out was the recommendation for reinforcement of car body doors of personal motor vehicles using molten polycarbonate materials. The thickness of 24 mm resulted in such increase of door burglar resistance that used small firearm ammunition could not penetrate this barrier.

Summary
State of protection of persons and property level follows development of external and internal security environment in which they operate. Democratization of firearm ownership created relatively new phenomenon of security risk which until now correlated mainly with contracted attacks focused on lives and health of risk groups of persons (e.g. important political officials, members of the Government or Justice, ambassadors, members of criminal organizations, etc.). High cost of said types of personal motor vehicles, as well as the modifications, significantly lowers their availability to wider public (average price of reinforced personal motor vehicle moves around 200 000 €). For this reason, the target customers of modified (armoured) vehicles are mainly politicians, ambassadors, entrepreneurs or bosses of criminal organizations. Other concerned groups of persons are insufficiently protected against attacks with firearms from the viewpoint of burglar resistance of commercially used vehicles
