Study of wear performance and mechanical properties of HDPE on addition of CNT fillers

Abstract

Carbon nanotube (CNT)/High-Density Polyethylene (HDPE) nanocomposite specimens were prepared with varying concentrations of 0, 0.04, 0.12 wt% by using ethanol as solvent followed by sonication and magnetic stirring for homogeneous distribution of CNT throughout the composite. To find variation in different mechanical properties like the modulus of elasticity, yield strength, tensile test was conducted and observed that the addition of nanofillers enhances the modulus of elasticity by 24.4 percent, and Yield Strength by 5.19 percent, with 0.12 percent CNT Toughness was evaluated by Charpy and Izod tests and found that it was improved by adding CNT nanofillers. Toughness improvement by the Izod test was 35 percent and by Charpy test, it was 4.76 percent with 0.12 percent CNT. The pin on the disc wear test exhibits depletion on the wear of nanocomposites. Even compared with the available theoretical model and found maximum 2.43 percent error in results for modulus of elasticity.
