Mechanical properties of carbon nanotubes, their experimental measurements and applications.Keywords: Carbon nanotubes, mechanical properties, composite materialsCarbon nanotubes (CNTs) present current and potential applications in construction materials such as polymer composites due to their excellent mechanical properties. The unprecedented values ​​of Young's modulus, stiffness, strength and resilience make it a perfect material in mechanical applications such as polymer composites. The use of CNTs to improve the mechanical properties of plastic is one of the current areas of study. These excellent mechanical properties imparted to materials are to some extent the result of their nanoscale. Fibers are classically used to improve the properties of materials. However, these fibers have dimensions ranging from a few microns to a few millimeters, which reduces the surface area per unit of mass available for interaction with materials. In the case of CNTs used as filler material, they offer a comparatively higher surface area per unit mass to interact with the material and, therefore, provide better mechanical properties. THE...
