Introduction Simulations and predictions of mechanical properties of various polymer matrix composites have been carried out [1, 5, 8, 12].
On fibers subjected to transverse tensile loading act different influences affecting the lamina’s mechanical behavior such as: stresses due to the loadings action; interference stresses; possible internal stresses and additional stresses that cause an increase in the matrix strain.
Moreover, at fibers volume fractions over 40%, the difference between these two factors increases.

The pull-in behavior of carbon nanotubes (CNTs), which is the sudden increase in the deflection of two interacting CNTs, affects the properties of CNT networks significantly, and thus becomes an important subject in applications.
Furthermore, the factors that affect the critical pull-in distance are also investigated.
Accordingly, the interactions between CNTs become a vital factor for the mechanical properties of CNT networks, including CNT reinforced composites, CNT fibers, and CNT-based devices.
Factors that affect the critical pull-in distance between CNTs The critical pull-in distance Dc presents the degree of interactions between CNTs.
