| Abstract |
The nanocomposites reinforced by carbon nanotubes (CNTs) exhibit great advantages in many fields. Many scholars focused on evaluating elastic properties of nanocomposites. There are somewhat disagreements between theoretical and experimental results. The waviness of the nanotubes is considered as one important factor affecting on the effective elastic modulus of nanocmposites. The present paper aims to develop a new model to replace the wavy carbon nanotubes with “effective fiber”. With the help of “effective fiber”, the effective modulus of nanocomposites with randomly oriented tubes can be predicted based on the micromechanics. In this study, the Mori-Tanaka effective-field method is modified, and the analytical expressions are derived for the effective elastic modulus of carbon nanotube-reinforced composites. The effects of waviness and agglomeration on the effective modulus are also analyzed. It is shown that they can reduce the stiffness of carbon nanotubes, significantly. Moreover, the effective elastic modulus of nanocomposites is very sensitive to the waviness and agglomeration. |
