Effects of Carbon Nanotube on Mechanical Properties of Composite plates - A Review Paper

Abstract

his review paper presents the findings of the re

searchers about the mechanical properties of compo

site materials by more detailed discussion of theoret

ical and mechanichal properties for the entire range of

the deformation amplitudes. Carbon nanotubes

(CNTs), due to their superlative mechanical and

physical properties, have shown a high potential to

improve properties of composite materials. Adding

CNTs into conventional composite materials at very

low weight fractions can improve mechanical proper

ties of the resulting nanocomposites. Among these

properties are an extremely high tensile strength and

stiffness. Scientists have estimated these values us

ing force fields to model the atomic interactions and

by using tools such as the atomic force microscope to

actually measure the elasticity and tensile strength.

Estimates of the stiffness of single walled carbon

nanotubes generally fall in the range of 0.9 – 1.5 TPa

with a tensile strength of approximately 100-150 GPa.
