Development of ABS polymer composites incorporating dual fillers of Titanium Dioxide and Tungsten

Abstract

Acrylonitrile Butadiene Styrene (ABS) and its composites are the most widely used material engineering applications. In this research work the reinforcement of fillers with the base polymer matrix ABS material was carried out to enhance certain properties. The unfilled ABS, loaded with dual fillers viz., Titanium Dioxide and Tungsten (TiO₂W) in weight (grams) the percentage of 2.5 %, 5 %, 7.5 % & 10 % respectively. Developed ABS composites of different compositions, were tested for their mechanical properties and material Flow Rate (MFR). Scanning Electron Microscopy (SEM) techniques were adopted to observe the morphology of developed composites. The results show a loss of tensile strength of around 57 % by incorporating both fillers by 10 wt%. Reduced composite strain shows an improvement in its hardness up to 10.33 % due to adding filler. There is the reduction of elongation in ABS/TiO₂Wcomposite of 70 % SEM images of the test samples depict the homogeneity of reinforced filler materials with ABS. Melt Flow Rate (MFR) characterization shows improvement in MFR around 82 %, due to filler adding from 2.5 wt% to 10 wt%.
