Abstract
The objective of this study is to examine the influence of carbon nanotube (CNT) pull-out from polyethylene (PE) matrix on the mechanical properties of CNT/PE composite. Materials Studio 8.0 has been used for carrying out the molecular dynamics (MD) simulation. The mechanical properties predicted are the Young's modulus and the interfacial shear stress (ISS). The effect of increase in strain on the Young's modulus of CNT has also been studied. A (5,5) armchair single walled carbon nanotube (SWCNT) of diameter 6.78Â Ã
and length of 49.2Â Ã
has been used. When the SWCNT was pulled out from the PE matrix by 10Â Ã
, there was 14.30% reduction in the longitudinal modulus (E33). When the displacement was increased to 50Â Ã
, E33 was reduced by 43.79% with respect to a fully embedded CNT. ISS was mainly distributed over the first and final 10Â Ã
of pull-out, in the stage I and stage III where the energy increments see a large change.
