Different material penetration analysis make and is worked out optimum strategy of simulations. material considered as Kevlar, plastic С-I19-55, E-glass, S-glass, steel i.e. that material, which characteristics available from open sources. The model of barrier consists of five layer cross armed composite material. The steel ball by mass 2g is directed in barrier at the speed of 2000 m/sec. The result of penetration of different material barrier is shown in graph.

Change of ball velocities during passing of cross-armed composite 5 layers package by thickness 2.4 mm each.

For comparison with steel barrier, there was is makes similar simulation, for five sheets of steel barrier and 13 sheets cross-armed composite. It is determined that in all events a splinter does not overpunch any barrier, but there is essential economy of weight of barrier.

The mass reduction in percent from similar steel barrier. Cross-armed composite 5 sheets on 2.4 mm each.

Thereby mass of barrier is reduced on greatly without loss of its efficiency.

Hit in steel monolith and in to layered composite.

Hit in steel shell and in to shell with filler.

Hit with destruction.

Hit on to frail and plastic material.

Hit by immediately five times pools on to one and three sheets.

Hit by various bullets.
