Mechanical Properties of Carbon Nanotubes Reinforced Composites: Experiment and Analytical Modeling

Abstract

New technology has been developed to obtain composite materials reinforced with pristine Multi-Wall Carbon Nanotubes (MWCNTs). Introduction of metallic magnetic particles upon the open tips of MWCNTs has been performed in order to induce, with the assistance of a magnetic field, an out-of-plane orientation of MWCNTs in a composite material. Micromechanical modeling of such composites is compared with the results of tensile and compressive tests and good agreement is observed. Results of the compressive tests show that the elastic energy accumulated in through-the-thickness direction reinforced composites is about two orders of magnitude higher than one in the pure matrix material.

A Simple Effective Flaw Model on Analyzing the Nanofiller Agglomeration Effect of Nanocomposite Materials

“…Nanocomposite materials have extensive applications in the fields of science, engineering, and medicine [1][2][3][4][5][6][7][8]. In general, mechanical properties of nanocomposites have been found to increase with increasing volume fractions of nanofillers.…”

The Effect of Surface Stresses on the Critical Debonding Stress Around Nanoparticles

“…Since the matrix mechanical stiffness properties are low, much attention, in the recent literature, has been paid to nanoscale reinforcements to significantly increase polymer stiffness, strength and toughness with low reinforcement concentrations (see, among the others, Wetzel et al, 2003, Wichmann et al, 2006, Cortes et al, 2010, Ayatollahi et al, 2011. Accordingly, an interest in the subject of the filler size effect at the nano meter scale has been arisen.…”

Ionic and electronic conductivities in carbon nanotubes – ionogel solid device

“…Applications of these composites may be found in the field of structural materials, transparent conducting films, sensors or electrodes. [10][11][12][13] Indeed, one of the key issues regarding the MWNTs based composites is the dispersion of the nanotubes in the matrix. Several strategies are used to achieve a good dispersion but a very promising one is the use of ILs as a dispersant.…”
