It is demonstrated that nanocomposites based on natural rubber with electrically carbon fillers exhibit high elastic properties, but an insufficient level of the electrical response. It is also shown that nanocomposites based on elastic polymer with mixture of dispersed nickel and carbon fibers exhibit the most appropriate response and electrical characteristics. They are promising for further investigation. It is shown that near the percolation point (which is the insulator- metal transition point) the electrical conductivity of the composite is changed up to six orders of magnitude due to changes in the effective density of carbon fillers during loading/unloading cycles. We found the hysteresis cycles existing due to inelastic processes under carbon filler packaging. The experiments on effects of radiation on nanocomposite propertied have been also carried out. It is shown that radiation increases adhesive and elastic properties of nanocomposites. But the electric response in cycles of loading/unloading remains almost unchanged. It is also found that only the first dose of radiation leads to changes in the position of percolation transition point. A review of the literature on the use of nanocomposites in space sensors and the estimation of the maximum absorbed dose of ionizing radiation, depending on the type of material and a satellite orbit have been made.
