Abstract
This work presents a simple and sensible equation for interphase strength in carbon nanotubes (CNT) reinforced nanocomposites by polymer medium strength, CNT size and interfacial/interphase items. Two models for tensile strength of nanocomposites based on Pukanszky and Kelly–Tyson approaches are linked to express the advanced equation. The calculations of this equation for some samples are evaluated and the roles of all factors in the interphase power are analyzed. The rational calculations of all interfacial/interphase items validate the equations. A high CNT aspect relation (reedy and long CNT) increases the interphase strength, while thick and short CNT cannot reinforce the interphase district. Additionally, thick CNT (R > 15 nm) significantly minimize the interphase power, but both interphase depth and interfacial shear power straightly control it. The high predictability of the established equation enables the prediction and optimization of interphase strength in the nanocomposites.
