Polymer-matrix composite materials are highly resistant to mechanical and chemical influences, as well as specific properties determining the quantity and type of filler material. To make the composite radiation-protective properties, used boron carbide powder and tungsten nanopowder fillers. With the addition of the filler deteriorating of the mechanical properties of the composite occurs and increasing its density takes place. For efficient practical use of composites is necessary to know the relation of physical and radiation-protective properties of all possible compositions. This paper presents a calculation of specific radiation-protective properties for a series of composites based on the excess of high molecular weight polyethylene with the addition of tungsten and boron carbide. The results presented here allow to optimize the composition of the materials on the efficiency radiation protection and mechanical properties and specific weight. The paper presents the results of an experimental study of radiation-protective and mechanical properties for a range of compositions of investigated composites.
