Mechanical and Thermal Characteristics of Polypropylene reinforced with Spheri-Glass-3000 produced by twin screw extruder

Abstract

The use of polymer reinforced with fillers has increased in recent years as their properties have improved. The thermoplastic matrix chosen for this study was Polypropylene (PP) and reinforcement as Spheri-glass-3000 (SGS). The melt mixing method was used to produce PP/SGS nanocomposites with the aid of twin-screw-extruder. Test samples was manufactured by injection-molding-machine. The mechanical and thermal properties of the PP/SGS nanocomposites produced have been investigated. Field-emission-scanning- electron-microscope was employed to examine SGS dispersion in the PP matrix. When SGS was added at 2.5 wt. % there was an increase in mechanical characteristics and thermal characteristics improved at 7.5 wt. % addition of SGS in PP matrix.
