Abstract
The effective material constants for CNT-based polymeric composites are studied. The analysis is based on the elasticity theory involving a spatial square representative volume element and the finite element method. The transversally isotropic body having aligned and uniformly distributed long carbon nanotubes is assumed. The perfect bonding between the carbon nanotubes and the matrix are considered. For such a material the five elastic material constants is needed to completely describe the elastic behavior. Related to the calculated material constants, the results are given and compared with the other models presented in the literature. Generally, the increase of the effective material constants normalized by the matrix modulus is observed.
