Simulation of Tribological Behavior of Abs Composites Reinforced with Graphene under Dry Sliding Condition

Abstract

Acrylonitrile Butadiene Styrene (ABS), an amorphous thermoplastic polymer with a glass transition temperature near 105 °C, consists of styrene (40–60%), acrylonitrile (15–35%), and polybutadiene (5–30%). In this work, graphene-reinforced ABS composites were fabricated by twin-screw extrusion and compression moulding. Microstructure was evaluated via optical microscopy; elemental composition was confirmed using Energy Dispersive Spectroscopy (EDS). Tribological performance was tested on a pin-on-disc tribometer under ASTM G99 standards, systematically varying load and sliding velocity. Grey Relational Analysis (GRA) identified optimal parameters for wear resistance. A finite element simulation of the pin-on-disc setup was performed in ANSYS, with outcomes validated against experimental findings. Results demonstrate that 2 wt% graphene reduced the wear rate of ABS by over 50% at 1.5 m/s, indicating strong potential for industrial applications requiring improved wear resistance.
