During the recent years, various solutions and techniques have been presented to improve the defects in composites but the best method is done with nano technology. In fact, two important effects of the nanoscale, which is the increase in the ratio of the particle's surface to its volume and the entry of the particle into the realm of quantum effects, change many of the physical and chemical properties of the nanoreinforcers. The use of nanoreinforcers in polymer-based nanocomposites, to a large extent, solves the weaknesses in the composites.
In this research, multi-scale modeling of hybrid nanocomposite with epoxy background and single-walled carbon nanotube and carbon nanoparticle reinforcements is presented. In this modeling, on the nano scale, the molecular dynamics method is used, and on the micro and macro scale, taking into account the influence of the intermediate phase, the analytical relations of micro mechanics and finite element simulation are used separately.
A good agreement between the results of these two methods was observed. The obtained results show that the simultaneous use of carbon nanoreinforcers and nanoparticles, hybrid nanocomposite, leads to more favorable properties
The results show the improvement of the elastic modulus of nanocomposite with the increase in the volume fraction of nano-reinforcers.
