SYNTHESIS OF COMPOSITE POLYMER FOR INDUSTRIAL APPLICATION

Prakash Sutar , D. K. Dond

Abstract: The Method of Fused Deposition Modelling is most popular rapid prototyping process producing parts layer by layer which is mainly made up of polymer. But the use of these parts is restricted because of low strength of plastic. To achieve efficient mechanical properties, metal composite polymer can be used which has not been used as feedstock material in FDM. Plastic component are most commonly produced by injection molding process. Wide variety of shapes and sizes of thin walled plastic parts are manufactured by this method . The aim of present study was to fabricate new metal composite and to investigate the effect of addition of metal powder on strength of polymer. As both FDM and Injection moulding are similar process the feasibility of metal composite feedstock was checked in injection moulding process. Experiments were carried out on parts produces by injection moulding process with different composition of metal and polymer. Six specimens with different proportions of aluminum and copper in polymer by weight were prepared as per the ASTM standard for Tensile and Flexural test. It can be concluded that addition of copper increases tensile strength of parts and aluminum increases bending strength of parts produced by Injection Moulding process
