Composite materials are widely used in modern production processes. Polymer composite materials, especially from the ABS group with different physical and mechanical properties have great potential in the field of electronic industry. To date, additive technologies are actively used, which requires a new approach to modeling the physical properties of various polymers, passing into a new state at the time of homogenization. For products made of polymeric materials with the use of additive technologies is characterized by the dependence of the final mechanical properties not only on the design, but also on the technological modes of manufacture, as in the manufacturing process is formed by a complex spatial structure of the layers, which leads to heterogeneity of the properties of different parts of the product. The structure of polymers is related to the properties of the final product and the level of quality.

In most practical cases, rotor systems are complicated mechanical objects. In solving a number of problems, such as investigated of dynamics and determining the technical state of elements of a rotor system, it is necessary to measure the spectral characteristics of vibration of some connection joints. As a rule, this is not always possible to do directly and leads to the need for a structural analysis of vibration processes. This analysis includes some questions such as partitioning complicated mechanical system on elementary systems, estimating relationships of coordinates and determination of unobservable parameters by observable. The graph method of connections is one of the most promising techniques of structural analysis. This method determines typical models of the dynamic processes of rotor systems with regard to characteristics of individual elements.
