Abstract
In this study, several models for the tensile modulus and strength of polymer/carbon nanotubes (CNT) nanocomposites (PCNT) are expressed as a function of percolation threshold. The roles of the CNT aspect ratio α and percolation threshold Ïp in the mechanical properties of PCNT are plotted according to the original and developed models. Furthermore, the effects of Ïp and various interfacial/interphase parameters on the PCNT tensile strength are presented through contour plots. The tensile modulus and strength of PCNT show a threshold at low Ïp values, indicating the important effect of the percolation behavior on the mechanical properties. Poor mechanical performances are seen at high Ïp values and different ranges of interfacial/interphase parameters. However, the lowest Ïp values and the highest ranges of interfacial/interphase parameters result in the most desirable PCNT strength.
