The influence of the structure on the properties of the metal-polymer composite consisting of a polymer matrix in the form of epoxy resin (ED-20) with butadiene-styrene rubber (BSK), dispersedly filled with copper nanoparticles, is investigated. In the framework of fractal analysis, the real diameter of the aggregates of the initial filler particles was calculated for various concentrations and size of the filling particles and for different compositions of the polymer matrix. The concept of the structure of a polymer composite as a combination of two fractals (multifractals) was substantially used, which allows to determine the principles of the polymer matrix plasticity changes and to reveal the main factors affecting the degree of perturbation of its structure. Using fractal analysis methods, the influence of factors on the fractal dimension of the surface of initial filler particles aggregates and on the pattern of its dependence both on the degree of aggregation and on the fractal dimension of the frame of the particle aggregate is investigated The proposed approach enables prediction the fi nal parameters of aggregates of nanoparticles as a function of the size of the initial particles, their concentration and chemical properties of the surface of the polymer matrix.
