The main objective of this research is to review and investigate the influence of carbon nanotube structure on the properties of\ncarbon nanotube and carbon nanotube-reinforced epoxy. Carbon nanotube and carbon nanotube-reinforced epoxy are currently\nbeing frequently used in many applications such as aerospace, automotive, and electronics industries due to their excellent\nproperties such as high tensile strength, high Youngâ??s modulus, and electrical and thermal conductivity. In this study, the\nobstacles to apply carbon nanotubes as fibers within the matrix have been introduced and discussed. Additionally, the epoxy\nproperties and application have been cited, and failure mechanisms of carbon nanotube-reinforced epoxy and geometries of\ncarbon nanotubes have been reviewed. Furthermore, with using experimental data and applying an analytical method, the effect\nof carbon nanotube diameter on interlaminar shear stress within the carbon nanotube-reinforced epoxy interface has been\nevaluated. Additionally, the effect of temperature variation on the value of interlaminar shear stress within the single-walled\ncarbon nanotube-reinforced epoxy interface has been discussed. Finally, the influence of the number of hexagons in the unit cell\non the Youngâ??s modulus of zigzag and armchair single-walled carbon nanotubes has been evaluated.
