Influence of micro- and nanonatural fillers on mechanical and physical properties of foamed sma composites

Abstract

This study is to investigate the reinforcing effects of fillers on mechanical and physical properties of foamed styrene-maleic anhydride (SMA) composites. According to the results, the best foaming was determined for starch reinforced SMA composite. The best result of expansion ratio was found as 22.75% to SMA/starch composites. Stereo light microscopy results demonstrated that the foamed cell distribution is heterogeneous and composed of two sections. The minimum density was found as 0.64 g/cm3 for foamed SMA/starch composites. Mechanical properties of all foamed composites were found to be low as compared to neat SMA composite
