ABS - CaSO4 Polymer Composite: Experimental Studies On Mechanical And Tribological Properties

Abstract

Objectives: The present study examines the effect of Calcium Sulphate (CaSO4) microparticles as filler materials and ABS as matrix materials on mechanical properties and wear performance of composite materials, which are injected into molds for preparation of the specimens. Methods: The CaSO4 microparticles are added at different weight fractions to the acrylonitrile butadiene styrene (ABS) polymer composites. Moreover, the reinforcement has improved tensile strength, wear properties, and hardness. Wear behavior was measured on ABS/ CaSO4 by a wear monitor (ASTM G99) and pin-ondisc type friction. As part of this experiment, the cutting speed, loading, and sliding distance of composite materials are considered and optimized for their properties. To observe and analyze the characteristics of this material, tensile strength and wear tests were conducted. By analyzing SEM images, we were able to study the fractured material’s morphology. In this study, an orthogonal array (L9) and control parameters were used to examine wear debris that explored the flacks and grooves of the content. Findings: An increase in toughness and modulus of resilience (due to an increase in filler content) and the contribution of normal load to wear rate (37.44%) constitute the most important contribution to work. Novelty : we have evaluated the various tribological and mechanical properties of polymer composite specimens using the Taguchi method. Keywords: ABS; Tensile strength; Pinondisc; SEM; Taguchi
