Abstract
The effective elastic moduli for carbon nanotube-based nanocomposites are derived and investigated. The conducted analyses based on the numerical homogenization procedure employ a spatial periodically arranged in a square array representative volume element and the finite element method. The transversely isotropic material having aligned and uniformly distributed long carbon nanotubes is considered. The perfect bonding between the carbon nanotubes and the matrix are assumed. Related to the transversely isotropic nanocomposite the five elastic material constants are needed to completely describe the elastic behavior. Based on the calculated material constants for the nanocomposite, the results are given and compared with the other values presented in the literature. In general, the increase of the effective material constants normalized by the matrix modulus is observed in comparison with pure polymeric matrix.
