Rezumat: As a subject of research was chosen the epoxy resin Primer-204 as a matrix and different types of dioxide silica nanopowder «Aerosil» with various average size and specific surface area of particles. With increase of the concentration the Young modulus of heterogeneous material increases. So at a volume concentration of 0.5% increase in Young's modulus of a mixture of powders A-200 and A-300, A-380 was 4.4%, 3.8% and 2.3% respectively. For the effect of the size epoxy filler concentrations up to 1% have been identified due to small differences in the values of variables. The mathematical model of the two-phased heterogeneous mixture was constructed and the equations expressing the Young module of a mixture from mechanical characteristics and volume concentration of components were obtained, according to hypotheses of equality of stress and strain. Prediction of the Young module of a heterogeneous material based on epoxy resin with filler is possible by means of the received mathematical model of identical stresses up to this volume concentration.
