Effect of Different Types of Nano-particles on the Morphology and Mechanical Properties of EPDM Foam

Foams are attractive materials because of their unique properties and applications in aerospace, transportation, isolation and engineering fields. Nanocomposites can be employed to achieve unique characteristics. It is convenient to use nano-particles for controlling the cell structure of foams and also to modify their mechanical properties. To further assess this effect, a variety geometrical shapes of nano-filler were employed in nanocomposites in order to investigate the effect of final foam micro structure and mechanical properties. Both Box-Behenken and factorial methods were chosen in this study for designing the samples. The performance of Box-Behenken experiment designs were evaluated. It was revealed that foam structure and presence of nano-particles in the structure is more effective than reinforcement of foam constitutive material.
