| Abstract: | It has been proved by a great deal of experimental data that polymers can be simultaneously strengthened and toughened when nano fillers are properly incorporated into them. In this paper, various strengthening and toughening mechanisms of polymer based nanocomposites have been reviewed. These mechanisms include physical and chemical interaction mechanism, tiny crazing mechanism, crack craze translation mechanism, critical thickness mechanism and physical crossing point mechanism. Explanation of existing experimental results have been done using these mechanisms. Consequently, it have been expected that these mechanisms will play important guiding roles in design and application of polymer based nanocomposites. |
