“…Incorporation of micro-scaled fillers has been shown to reduce wear rates of PTFE typically bỹ 100ˆwith >20 wt % filler loading [3,[6][7][8][9][10][11]. Early on, the wear-mitigating effect of these particles was attributed to preferential support of the normal load by the filler and disruption of subsurface crack propagation [6,12].…”

Abstract:In dry sliding conditions, polytetrafluoroethylene (PTFE) composites can form thin, uniform, and protective transfer films on hard, metallic counterfaces that may play a significant role in friction and wear control. Qualitative characterizations of transfer film morphology, composition, and adhesion to the counterface suggest they are all good predictors of friction and, particularly, wear performance. However, a lack of quantitative transfer film characterization methods and uncertainty regarding specific mechanisms of friction and wear control make definitive conclusions about causal relationships between transfer film and tribological properties difficult. This paper reviews the state of the art in the solid lubricant transfer film literature and highlights recent advances in quantitative characterization thereof.

“…The significant increase in flexural modulus with the addition of the lubricating filler to the glass-epoxy composites could possibly be due to synergism between polymer matrix and solid lubricant where lubricant does not interfere with the stress transfer role of the polymer matrix especially under flexural loading conditions [14]. Lancaster [15] pointed out that even with reinforcing fibers, the increase in stiffness of a composite may be greater than the increase in strength. For particulate fillers, there is generally a greater increase in stiffness (i.e.…”

The present work reveals the effect of the addition of commercial MoS 2 (10 wt%) particles on mechanical and two-body abrasive wear behavior of epoxy with/without glass fiber mat reinforcement. The composites were fabricated using casting and simple hand lay-up techniques followed by compression molding. The mechanical properties such as density, hardness, tensile, and flexural properties were determined as per ASTM standards. The abrasive wear testing was carried out using pin-on-disc wear tester for different loads and abrading distances at constant speed of 1 m/s. A significant reduction in wear loss and specific wear rate was noticed after the incorporation of MoS 2 filler allowing less wear of matrix during abrasion which in turn facilitated lower fiber damage. However the incorporation of MoS 2 particles had a detrimental effect on most of the mechanical properties of the composites. The worn surface features were investigated through scanning electron microscopy (SEM) in order to investigate the wear mechanisms.

“…Commercially many types of PTFE grades are available which are processed and reinforced for selective applications such as solid lubrication and self-lubricating polymer gears. PTFE is often filled with glass fiber, graphite, bronze, carbon, and Molybdenum Disulphide (MoS 2 ) for the enhancement of properties [92]. The fillers are loaded in some weight percentages to enhance and nurture the properties.…”

High-performance commodity polymers are in demand due to low cost, durability, easy productivity, and recycling ability. This article comprises a survey on the performance properties of polytetrafluoroethylene (PTFE) fluoropolymer. It is a well-known choice for coatings, insulation, thermal sealing, lubrication, bearings, and clinical applications. PTFE was engineered in many forms as a function of loading nano and micro fillers for different purposes and the improved properties and performance were addressed by the researchers. Hence, we disclosed the various casting routes of PTFE which is feasible for reliable processing to serve in domestic and industrial applications.
