Welding Behaviour of Graphene Oxide Reinforced High Density Polyethylene Nanocomposites

Abstract

Welding is used to produce bonded joints with technical properties to the base material. The thermoplastic nanocomposites are more familiar in recent days due to their excessive automotive applications. The specimens were prepared by pure HDPE and various weight ratios HDPE with nanofiller composites by melt mixing method and required shape produced by using compression moulding. The nanofiller will be chosen in this study is Graphene oxide. The main scope of using Graphene oxide was to enhance the mechanical properties of the prepared specimens. In this work, Ultrasonic welding had been used to carry out the test on both pure HDPE and HDPE with grapheme oxide. Mechanical properties were analyzed for both pure HDPE and grapheme oxide filled HDPE of both body part and welded part joints are compared.The mechanical properties of tensile strength and youngs modulus and elongation of the body part for graphene oxide filled HDPE was substantially increased due to the presence of compatabilizer.Thus the result improves the weld strength of the nanofilled polymer matrix with compatabilizer
