Method for computer modeling of elastic characteristics of multilayer composite materials

Modern polymer composite materials are widely used in the aerospace industry. Creation of new materials with the required characteristics is one of the most important directions for the development of the industry, especially in connection with the need to quickly resolve the issues related to import substitution. The paper presents the results of calculation of the effective elastic characteristics of multilayer polymer composite materials with differently oriented layer reinforcement structure. The model of reinforced material based on the assumption that the composite material consists of quasi-homogeneous transversally isotropic perfectly connected layers is used. The obtained calculation results are in good agreement with both experimental data and the results of calculations of commercial packages and can be used to automate scientific and engineering calculations in the selection of components and methodology of their placement according to the given characteristics of polymer composite materials.
