Investigations of Melt Flow Behavior of Aluminium Metal Particle-Reinforced HDPE Composites

Abstract

In this study, the process for the development of the high-density polyethylene (HDPE) and the Aluminium (Al) powder-reinforced composites has been outlined by the single screw extruder for the feedstock filament study. The filament has been prepared on the single screw extruder. The study is illustrated with two different stages: (a) melt flow index (MFI) of 10[Formula: see text]g HDPE reinforced (0%–50%) with varying concentrations of Al-powder and (b) extrusion of the filament utilizing the ratio of 75% HDPE and 25% Al-powder for distinguished experimental parameters. The result of this study suggests the best filament extrusion setting for the different heat-treated and nonheat-treated conditions for Young’s modulus. The extrusion parameters are [Formula: see text]C, [Formula: see text]C for heat-treated (HT) and nonheat-treated (NHT) conditions at a nozzle diameter of 1.75[Formula: see text]mm. The result has been supported by universal testing machine (UTM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). HDPE-Al-2 has the highest mechanical properties [Formula: see text]C at 6[Formula: see text]rpm heat treated. The crystallinity of the filament increased to 64% with the Al-powder reinforcement along with enhancement of the properties of Young’s modulus of heat-treated samples.
