description: This work is devoted to the experimental study of nonlinear elastic moduli of samples of nanocomposites based on polymers. Tasks that were solved during the study: 1. Creation of an experimental setup for measuring nonlinear elastic moduli. 2. Carrying out measurements in the study of several samples of pure polystyrene and polystyrene with the addition of nanoinclusions. 3. Development of the program and its application for processing experimental data and calculating the third-order elastic moduli in the studied samples. 4. Analysis of the obtained data and conclusions regarding the presence or absence of the effect of nanoparticles on the elastic properties of the polymer.The experiment was carried out using 5 samples, 2 samples were pure polymer and 3 samples were polymer with the addition of nanoinclusions. To calculate the nonlinear elastic moduli, an acoustic signal was passed through the sample under static pressure. The obtained signal was used to plot the pressure dependence of the speed of the soundsignal passing through the sample. In the course of the analysis of the obtained dependences, nonlinear elastic moduli and nonlinearity coefficients were calculated. Based on the results obtained, a conclusion was drawn about the elastic properties of thesamples and the effect of nanoinclusions on the properties of the nanocomposite.
