The work shows that nanocomposites have great potential for their further development. It has been
established that when using homogeneous particles of polymers and metals, almost all the physical and
chemical properties of both the original composites and the nanocomposite as a whole change significantly.
The operation of sealing units is analyzed taking into account the compatibility of sealing materials with the
environment and criteria are selected for evaluating composite materials based on a set of physical and
mechanical parameters. Based on this, a relationship has been established between the ratio of hardness to
yield strength and the structure of nanocomposites. It has been shown that a decrease in the elastic modulus
due to the aggregation of filler particles with an increase in its content determines a decrease in the ductility
of the composite.
