Abstract:

Polymer-based composite reinforced with low contents of nanoparticles have received considerable attention. Many applications including biomedical used microfibers combined with nanoparticles to improve mechanical properties of materials. Various nanoparticles with different shapes and sizes are used to improve the mechanical properties of resin-based matrix. In this talk, we will demonstrate the mechanical advantage of nanoparticle reinforced composite in comparison with the microfiber reinforced composite through combined mean-field homogenization and finite element methods. The stresses in the microstructure were analyzed with the representative volume element. The effect of the interface between matrix and nanoparticle, the filler sizes, as well as the clustering and distribution of clusters on the mechanical of the composite are presented.
