On Young’s modulus of multi-walled carbon nanotubes

Abstract

Carbon nanotubes (CNTs) were discovered by Iijima in 1991 as the fourth form of carbon. Carbon nanotubes are the ultimate carbon fibres because of their high Young's modulus of ≈ 1 TPa which is very useful for load transfer in nanocomposites. In the present work, CNT/Al nanocomposites were fabricated by the powder metallurgy technique and after extrusion of the nanocomposites bright field transmission electron microscopic (TEM) studies were carried out. From the TEM images so obtained, a novel method of ascertaining the Young's modulus of multi-walled carbon nanotubes is worked out in the present paper which turns out to be 0⋅9 TPa which is consistent with the experimental results.

Mechanical performance of styrene-butadiene-rubber filled with carbon nanoparticles prepared by mechanical mixing

“…In these models, the effective Young's modulus of MWCNT was considered to be 1000 GPa according to [23,53,54] while for the unfilled SBR, the Young's modulus was determined to be 1.37 MPa. In this work, effective filler volume fraction, illustrated in Fig.…”

Effects of carbon fillers on tensile and flexural properties in polypropylene‐based resins

“…In previous modeling research on nylon 6,6 and polycarbonate composites,52 the modulus of Thermocarb TC‐300 used was 827 GPa and the modulus of Ketjenblack EC‐600 JD was 827 GPa. The modulus of carbon nanotubes is available in the recent literature53, 54, 72, 73 and in the range of 900–1060 GPa. As such, we use 1000 GPa for our modeling work.…”

Comparative study of dielectric and mechanical properties of HDPE-MWCNT-SiO 2 nanocomposites

“…(8), d represents the ratio of filler modulus (taken to be 1 TPa for MWCNT [31]) to matrix modulus. The third model includes an adhesion parameter 'j' which varies from 0 to 1.…”
