| This study was conducted to compare the properties of modified montmorillonite clay-filled resins with talc-filled resins. The composites of polycarbonate, acrylonitrile-butadiene-styrene, polycarbonate-acrylonitrile-butadiene styrene blend and polyamide were prepared by melt blending of the clays and the base resins in a laboratory scale single screw extruder. Standard test specimens were injection molded from the blends. Tests conducted on each blend included the investigation of tensile properties (tensile modulus, strength and percent elongation), and the dynamic mechanical rheological properties. Testing revealed that the tensile moduli and strength at break increased while the elongation at break decreased with the addition of the clays. Rheological properties showed that the storage moduli of the blends decreased with an increase in temperature. There was a minimal difference in properties when comparing both, nano clay-filled and talc-filled composites. |
