Abstract
  • Today nano scale materials are being used for wide range of applications. One promising topic in nano scale materials is using them for reinforcement of different polymeric materials to reach desirable stiffness properties. The stiffness of these materials is mostly found experimentally because the nanocomposite community lacks a decent analytical model that can provide a reliable prediction. Modeling can be done using both numerical and analytical methods. Numerical methods can be time-consuming, expensive and need the expertise to implement right assumptions and extrapolate useful data. But they can be more reliable, if done correctly, compared with the analytical method. Analytical methods use a mathematical equation that has been derived considering the physics of the problem. Analytical methods are equations that predict properties on nanocomposites based on properties of components at different conditions (e.g., temperature, and more) and are more desired. For this work, we used a new Monte Carlo finite element analysis (FEA) method as a numerical method to model the stiffness of different nanocomposites and compared them with different analytical models to find the most accurate model that can predict the stiffness of nanocomposites as a function of its components? properties. We then com- pared different models with experimental results using cellulose nanocrystal composites.
