Preparation and Studying of Some Mechanical Properties of Polymer Blend

Abstract

In the modern polymers’ industry, polymer blends are widely used, due to their wide range of properties as compared to individual polymers, where it applied in the design of composite and biocompatible materials, adhesion and colloidal stability... etc. This work investigate possibility of improving mechanical properties of epoxy resin EP by blending with polycarbonate PC, with different weight fractions, (5, 10, 15, 20, 25) %, by mechanical mixing technique, the mechanical tests that depended in this work were; tensile test, bending and flexural strength test, and impact test. The results show development of mechanical behavior with increasing PC content in blend from brittle to ductile, where the experiments show increasing values of elongation, young modules, flexural strength, flexural modules, impact strength, and fracture toughness, while decreasing of ultimate tensile strength comparing with that of pure epoxy.
