Tuning of final performances of unsaturated polyester composites with inorganic microsphere/platelet hybrid reinforcers

Physical properties of fly ash/mica hybrid reinforced unsaturated polyester composites in both uncured and cured state have been studied with special reference to the effect of loading composition, nature of filler surfaces and surface treatment of fillers. Besides, effect of filler surfaces on curing characteristics of composites were all examined. In uncured state, viscosity measurement for composites was carried out. Tensile properties for cured fly ash/mica hybrid reinforced composites were found to increase with addition of mica in total filler. Effects of filler composition and silanization on loss factor (tan δ) were all discussed.
