In this paper, the engineering constants of carbon nanotube based unidirectional carbon fiber reinforced composite lamina determined theoretically with two different approaches were obtained under concentrated and distributed load.Abstract:
Because of increased usage areas, and advances in characterization of the nanostructured materials, determination of the engineering properties of composites that includes carbon nanotubes has gained importance. It is possible to designate material properties of carbon nanotube based composites theoretically and experimentally. In this study, engineering constants of carbon nanotube based unidirectional carbon fiber reinforced composite lamina determined theoretically with two different approaches. Then, a composite plate whose laminas were stacked up as a [0°/+45°/-45°/90°]s layup was built up in ANSYS, ACP Module. Finally, three point bending analyzes were performed separately under concentrated and distributed load. The results showed that there were negligible differences between the engineering constants obtained from two different theoretical approaches. Engineering constants, E1, E2, G12 and G23, increased as the added carbon nanotube fraction is increased. Besides that, flexural rigidity of composite plate also showed ever-decreasingly increase, as carbon nanotube content is increased. The results of theoretical and numerical bending analyzes exhibited a good agreement with the maximum percentage relative error of 9.1.read more

Enhanced mechanical properties of nanocomposites at low graphene content.
TL;DR: Graphene platelets significantly out-perform carbon nanotube additives in terms of mechanical properties enhancement, and may be related to their high specific surface area, enhanced nanofiller-matrix adhesion/interlocking arising from their wrinkled (rough) surface, as well as the two-dimensional geometry of graphene platelets.

Influence of nano-modification on the mechanical and electrical properties of conventional fibre-reinforced composites
TL;DR: In this article, a filtering effect of nano-particles by the glass-fibre bundles was not observed, while the tensile properties were not affected by the nano-fillers, due to the dominating effect of the fibre-reinforcement.
