Mechanical Properties of Glass Beads Filled Polypropylene Composites

摘要

In this study, the mechanical properties of glass beads filled polypropylene composites have been investigated. Polypropylene (PP) was filled with different volume fractions and different sizes of glass beads (GBs). The glass beads used were: 4, 11, and 66 μm in diameters. Tensile specimens of PP/GB composites were injection molded and their mechanical properties were found by a series of uniaxial tensile tests. Young's modulus, work of fracture, Charpy impact strength and tensile strength of the specimens were determined. The results illustrated that the Young's modulus increased almost linearly with increasing glass bead concentration according to the Einstein equation.
