Correlation between Mechanical Properties with Specific Wear Rate and the Coefficient of Friction of Graphite/Epoxy Composites

Abstract

The correlation between the mechanical properties of Fillers/Epoxy composites and their tribological behavior was investigated. Tensile, hardness, wear, and friction tests were conducted for Neat Epoxy (NE), Graphite/Epoxy composites (GE), and Data Palm Fiber/Epoxy with or without Graphite composites (GFE and FE). The correlation was made between the tensile strength, the modulus of elasticity, elongation at the break, and the hardness, as an individual or a combined factor, with the specific wear rate (SWR) and coefficient of friction (COF) of composites. In general, graphite as an additive to polymeric composite has had an eclectic effect on mechanical properties, whereas it has led to a positive effect on tribological properties, whilst date palm fibers (DPFs), as reinforcement for polymeric composite, promoted a mechanical performance with a slight improvement to the tribological performance. Statistically, this study reveals that there is no strong confirmation of any marked correlation between the mechanical and the specific wear rate of filler/Epoxy composites. There is, however, a remarkable correlation between the mechanical properties and the friction coefficient of filler/Epoxy composites.

Study of effective parameters on wear behavior of rubbers based on statistical methods

“…Moreover, under the applying load, the mechanical properties differ at contact points . These mechanical properties also play a significant role in the friction behavior of composite polymers; the higher tensile strength and elongation at break result in a lower coefficient of friction …”

“…26 These mechanical properties also play a significant role in the friction behavior of composite polymers; the higher tensile strength and elongation at break result in a lower coefficient of friction. 32 In general, there are factors, which affect wear and friction of elastomers and polymers. Review of literature shows that statistical studies regarding the effect of external process parameters on wear are mostly focused on polymers and their composites, 4,33-35 while wear and friction behavior of rubbers are more complex because their wear mechanism differs significantly under variable conditions.…”

Mechanical behaviour of graphene and carbon fibre reinforced epoxy based hybrid nanocomposites for orthotic callipers

“…The standard epoxy matrix has a two-component with bisphenol A, based resin, AW 106 and an amine-based hardener, HV 953IN. The standard epoxy resin was chosen as matrix material owing to its greater mechanical strength, higher thermal stability, and negligible dimensional shrinkage on curing, high viscosity and density than the other thermoset polymer resins like polyester [15]. Graphene, with properties such as flexibility, transparency, ultra-strength, elastic nature, scalable, transferable, corrosion resistance, electrically conducting etc., has evolved and dominated the materials world.…”

Tribological Behavior of Phenolic Resin-Based Friction Composites Filled with Graphite

“…The results showed that the interaction of furan resin and wear debris of graphite was useful to reduce the wear rate of furan resin-Gr composite. Alajmi et al [42] investigated the correlation between mechanical properties with specific wear rate and the coefficient of friction of Gr-epoxy composites. They concluded that 2 of 13 graphite led to eclectic effects on mechanical properties of graphite/epoxy composites at the same time as affirmative effects on tribological properties of graphite/epoxy composites.…”
