This review paper presents tribological and mechanical characteristics of hybrid polymer composite materials that exhibit low friction and low wear. Polymer fiber reinforced materials possess low weight and high specific quality along with high specific stiffness. This study targets a critical review of wear and frictional characteristics of hybrid polymer composite materials. Tribological properties have been evaluated by various researchers using a rotating pin‐on‐disc tribometer and reciprocating wear testing machine. Most likely filler materials are carbon, graphite, nano silica, bronze, glass fibers, MoS2, and polytetrafluoroethylene (PTFE) added in the polyether ether ketone (PEEK), polyamide 66, thermoses polymer, etc. It improves mechanical and tribological properties of hybrid composite materials. This review paper aims to highlights the comparative study of various fillers added in PEEK, Polyamide 66, and thermoses polymer hybrid materials. Recently hybrid composites are used in wide range of applications since it has light weight and high strength.

“…The influences of filler, load, and sliding distance were evaluated as a part of the trial results, and the specimen was found to have a lower wear rate than pristine PTFE. Also, it was concluded that the wear rate is directly proportional to the load and the sliding velocity [12]. Daniel and Liu presented a comprehensive investigation of graphene and carbon fibers reinforcing polyimide and the remarkable features of both materials.…”

This manuscript presents an experimental investigation of the friction and wear properties of poly (methyl methacrylate) (PMMA) nanocomposites reinforced with functionalized multi-walled carbon nanotubes (MWCNTs). The aim of this study is to evaluate the potential of MWCNTs as a reinforcement material for enhancing the tribological performance of PMMA. Three types of multi-walled carbon nanotubes, i.e., pristine, hydroxyl functionalized, and carboxyl functionalized, were utilized in this study. The nanocomposite samples were prepared by dispersing varying concentrations of MWCNTs (0.1 wt.%, 0.5 wt.%, and 1 wt.%) within the PMMA matrix via a 3D mixing approach, followed by injection molding/compression molding. The resulting nanocomposite films were characterized using scanning electron microscopy (SEM) to observe the dispersion of MWCNTs within the PMMA matrix. The friction and wear tests were conducted using a pin-on-disk tribometer under dry sliding conditions. The effects of functionalization and MWCNT content on the tribological behaviors of the nanocomposites were analyzed. The nanocomposites exhibited lower friction coefficients and reduced wear rates compared to pure PMMA. The lowest friction coefficient and wear rate were achieved at an optimum MWCNT loading of 0.5 wt.%. It was further revealed that the amount of MWCNT reinforcement, average load, and track diameter significantly affect the coefficient of friction (COF) and rate of wear. The COF and wear rate are best at a filler loading of 0.5 wt.%, a 20 Kg load, and 90 mm. The improved tribological performance of the MWCNT-reinforced PMMA nanocomposites can be attributed to the effective transfer of load between the MWCNTs and the PMMA matrix, as well as the reinforcement effect of the MWCNTs. The MWCNTs acted as reinforcing agents, enhancing the mechanical properties and wear resistance of the nanocomposites.
