The paper represents the results of the experimental determination of impact resistance and the principles of assessing the ballistic resistance of organoplastics. Organoplastics are presented as a composite material consisting of unsaturated polyester resin (matrix) and a reinforcing component of organic origin, mainly aramid fiber. Reinforcing components are fabrics of various weaves, canvases, and discrete fiber. The polyester resin contains an additive that provides biodegradability of the binding component. In the case of using a biodegradable reinforcing component or a mineral-based reinforcing component, the organoplastics will cause minimal damage to the environment after the exploitation period. Experimental data on the impact resistance of the material were obtained on a 3 m high impact coper on the basis of fixing the work of destruction of samples of organoplastics of a certain thickness. The essence of the ballistic stability assessment was to compile a system of differential equations describing the degree of change in kinetic energy when a bullet (fragment) hits the material and the nature of the decrease in the speed of their contact in the barrier. To solve the system of equations, initial data are required: time, bullet velocity, length of the non-working part of the bullet, cross-sectional area, and mass of the bullet (fragment). The solution of the problem determines the degree of decrease in the speed of the bullet (fragment) contact with the barrier. The obtained research results are suitable for protecting the object from the impact and designing light armor protection of vehicles and other means.
