Polymer composite materials have high resistance to mechanical and chemical influences. These properties depend on the quantity and properties of the filler. We used boron carbide and tungsten nanopowder as a filler to obtain radiation-protective material. Mechanical properties of the composite decrease with the addition of the filler and  it’s density increases. Knowledge of the relation of physical and radiation-protective properties of all possible compositions is required for efficient practical use of composites. The results of physical and mechanical tests represent the whole spectrum of possible compositions of composites based on ultrahigh molecular weight polyethylene. The presented results of mechanical tests allow to optimize the composition of under certain tasks. According to the results of mechanical tests of layed samples can be judged on the degree of degradation of the material in time.
