A study of microstructure and mechanical properties of copper filled Polypropylene and copper filled Epoxy

Abstract

In this project, metal filled polymer composite had been produced by using powder metallurgy concept and cold pressing method. The processing method had influenced the properties of composite system and to establish the quantitative relationship between the mixing ratios and its final properties. Based on the results obtained, the physical and mechanical properties of these composite allow to draw some specific conclusion about the structural features of the system with the basic notions of the properties of polymer filled metal composite are reviewed. The pore and void formation in sintering and curing polymer is studied. The main feature of the systems studied is the fact that the transition of the polymer at very high temperature (sintering) and at its melting temperature (curing) of the polymer. In general, at very high temperature, the polymer in the sample will degrade and burn out and increasing the porosity, whereas the density of the sample decreased. At low temperature of 150°C and 200°C, the polymer in the copper matrix were expanded and bond together to form a composite with high hardness but lower in densities and strength. The morphology was carried out to study the behaviors of porosity present in the composites.
