A Review on Influence of Titanium Dioxide, Molybdenum Disulfide and Glass Fibers on Polytetrafluoroethylene (Ptfe) for Wear Resistance

Abstract

This study investigates the tribological performance of polytetrafluoroethylene (PTFE) composites reinforced with a synergistic combination of titanium dioxide (TiO2), molybdenum disulfide (MoS2), and glass fibers. The fabrication process involves blending the materials in an electric blender, followed by the addition of chopped glass fibers. The resulting mixture is molded, cold pressed, and sintered to create PTFE composites with varying compositions. The tribological tests are conducted under fixed conditions, including constant velocities of 1 m/s, 2 m/s, and 3 m/s, with load increments until specimen failure. The experiments are carried out using a hydraulic motor to apply loads rapidly, and various parameters such as normal load, speed, temperature, and friction torque are recorded. The study aims to understand the influence of each ingredient on the tribological behavior of the composite, with a focus on wear rates, specific wear energy, and specific wear rate calculations. The results contribute valuable insights into optimizing PTFE composites for enhanced friction and wear resistance, particularly in applications requiring superior tribological properties.
