This paper presents data on the development of polymer composite materials based on thermoplastic elastomers. As starting materials for the synthesis of the matrix components were selected as follows: isotactic polypropylene and ternary ethylene-propylene-diene elastomer (EPDM). Diene component in EPDM are ethylidene norbornene composition in an amount of 4-5%. Dynamic vulcanization was carried out using the elastomer element sulfur. The filler polymer composite materials used silica gel with dimethyl polysiloxane. Synthesis was carried out by filling the sol-gel technology. The filler content in the composite varied from 10 to 80% by weight. Mixing of filler and the matrix was performed in a laboratory twin-rotor mixer, type "Brabender". It is found that the maximum possible filler content of the matrix used was 80%. With the introduction of more filler mixing of the components it has been difficult. When the filler content from 10 to 70% of parameters such as tensile strength, flexural strength and modulus of longitudinal elasticity increasing and administered at higher filler and 80 wt%. markedly reduced. Thus, it can be concluded that the content of filler in the composite is 70%. Further research should be directed to the evaluation of the radiation resistance of the developed composite materials.
