ABSTRACT
Modeling of the properties of multi-structured materials at various levels of its behavior has become the subject of considerable interest in the scientific and engineering community in years, which is explained by the development of modeling methods that predict the behavior of materials. When developing new composites, the reliable mathematical models allow an engineer to predict their properties over a wide range of concentrations and physical parameters of constituent components. The use of adequate phenomenological models of material properties allow purposeful search for promising composites for solving many applied problems. In engineering practice, among all composites, fibrous composite materials that combine ease with the strength and rigidity in given directions are used. Fibrous composite materials based on glass, carbon, boron, basalt, organic fibers are widely used in critical structures in engineering, aerospace engineering, industrial and civil construction. The right choice of components, taking into account their properties, relationships and structure, allows obtaining composite materials with specified properties.
