ANALYSIS OF MICROSTRUCTURE OF FUMED SILICA REINFORCED POLYESTER COMPOSITES

Fumed silica reinforced unsaturated polyester compo sites are developed by simple mechanical stirring and compression molding technique respectively. Investigation on morphological characteristics of fumed silica reinforced polyester composite is presented. The effect of fumed silica taken as different weight fractions and their interactive influences on the morphological characteristics of these composites h as been studied. The results showed that amorphosity is inversely proportional to crystallinity with increasing the filler loading. The study revealed t hat fumed silica particle addition in polyester composite has dramatic effect on the microstructure of polyester fumed silica composites.
