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.
Highlights
In the last two decades, Polymer composites have been used in a wide variety of industrial applications, such as automobiles, furniture, and construction [1,2,3,4]
This study reported that the correlation between the wear volume and mechanical properties emerged with only some of the factors of the selected mechanical properties, such as (Se)−1 and (HSe)−1
The present study investigates the correlation between the specific wear rate (SWR) and the coefficient of friction (COF) of neat epoxy and its composites, based on different graphite percentages and date palm fibers with their mechanical properties
Summary
In the last two decades, Polymer composites have been used in a wide variety of industrial applications, such as automobiles, furniture, and construction [1,2,3,4] This is mainly due to their advantages compared to metal materials, such as their lower cost, low density, chemical resistance, high strength-to-weight ratio, less damage to processing equipment, and good relative mechanical properties [5,6,7,8]. In order to get a clear understanding of the relation between mechanical properties and the tribological performance of polymer composites, several studies have combined mechanical properties in a single factor as opposed to specific wear rate or friction coefficient. The present study investigates the correlation between the specific wear rate (SWR) and the coefficient of friction (COF) of neat epoxy and its composites, based on different graphite percentages and date palm fibers with their mechanical properties
