Abstract/Description: Many researchers have studied the interfacial shear stress (ISS) in nanocomposites through theoretical calculation, computational simulation or sophisticated nanomanipulation experiment measurement. In this research, we attempt to directly calculate ISS values in actual nanocomposites based on a modified Cox's model using tensile test results of various macroscopic carbon nanotube (CNT) nanocomposites. Young's modulus, tensile strength and strain of CNT ropes rather than individual CNT properties were applied into the model. The effects of functionalization, CNT rope length, volume fraction and CNT type (SWNT, DWNT, MWNT) on interfacial shear stress were studied. It was found that the functionalization increased the mechanical properties of both interfacial bonding and DWNT and MWNT rope themselves; however, it decreased the mechanical properties of SWNT ropes. The major failure mode of the CNT nanocomposites was identified to be CNT rope rupture. The calculation results revealed that the ISS values in the nanocomposites are comparable with the ones reported in literature.
