“…However, self-lubricating characteristics of the graphite particulates also reduce the wear magnitude. 6 The addition of 5 wt% of silicon carbide mixed with 35 wt% of graphite powder improved the wear resistance of neat epoxy by 85% as observed by Srinivas and Bhagyasekhar. 7 Similarly, the addition of potassium titanate whisker has also been found to improve the wear resistance of epoxy.…”

Waste marble dust is a solid waste generated during the cutting and polishing of marble pieces in construction sites and also in marble processing industries. This paper reports on the utilization of this waste as a filler material in particulate-filled polymer composite. Polyester-based composites are prepared with different weight proportions of waste marble dust and the dry sliding wear behavior of these composites is studied. Wear trials are conducted using a pin-on-disc test apparatus based on the Taguchi’s L25 orthogonal array as per ASTM G 99-05. The effects of different parameters on the specific wear rate of the composites are studied and an optimum combination of parameters is obtained for the least wear rate. Based on the experimental data, a prediction model using the artificial neural network is used to predict the specific wear rate of the composites at a wider range of operating parameters, within and beyond the test region. The morphologies of the worn surfaces are studied by a scanning electron microscope to ascertain the wear mechanism of the composites at different conditions. This work thus opens up a new avenue for the value added utilization of a waste like marble dust in tribological applications.

“…In Figure 13, evolution of COF can be divided into three stages: Initial run-in period, slow growth period, and steady-state period [25]. Each stage is divided using a segmentation fitting method, and the slope of the fitting line represents the growth rate of COF in this stage.…”

“…The plasticity limit of the glass fiber was reached during sliding movement, contributing to brittle fracture [25]. However, the presence of graphene in the resin matrix can improve the bonding strength between fiber and matrix, allowing broken fibers in the matrix to endure the sliding wear for longer.…”

Preparation and Tribological Study of Graphene Coating on Glass Fiber-Reinforced Composite Using Modified Percolating-Assisted Resin Film Infusion Method

Tribological properties of glass fiber-reinforced polymer (GFRP) composites used in reciprocating contact should be improved to secure the efficiency and safety because of risks of abrasion, adhesion, and fatigue deficiency amidst fiber, matrix, or interphase. This paper investigates the influence of graphene reinforcement on the wear resistance of a GFRP composite. Graphene was integrated into a typical GFRP composite as the surface coating using a modified resin film infusion method with the percolating paper assisted. Dry reciprocating sliding tests were performed against a stainless steel ball moving in a direction 45 degrees to the fiber orientation. The morphology of the worn surface was observed, and the corresponding wear mechanisms are discussed. Results suggest that the prepared graphene coating improves the wear resistance of the GFRP composite. The protected GFRP laminates remained intact during the first 20 min of the wear test and only a small fraction of fibers were broken after 60 min test. Furthermore, abrasive debris and fiber breaks originating from composite were markedly reduced, likely owing to the formation of a protective transfer film between the surface of the modified composite and the rubbing counterpart.

“…The reinforcement percentage has a higher impact on the wear rate, followed by the stacking sequence. Sudheer et al [8] determined the wear and mechanical properties of epoxy hybrid composites with graphite, glass and PTW as reinforcing materials. They observed improvement in the wear behavior of the hybrid composites.…”

The numerical approach for the study of wear performance of breadfruit seed shell ash particles (BFSAp) and Sodium hydroxide (OH)/silane (APS)functionalized Momordica angustisepala fiber (MAf)/epoxy hybrid composites were investigated. The MAf fibers were treated with an OH-APS solution. Hardness values, wear rate and wear mechanism of the samples were determined. A 65.82% improvement in wear resistance was obtained at the load of 30N of 30wt%MAf-20wt%BFSAp composite. The wear rate and wear damage followed in this order: epoxy(matrix)˂epoxy/30wt%MAf-20wt%BFSAp˂epoxy/OH-APS treated 30wt%MAf-20wt%BFSAp composites. The wear mechanism observed in this work is a combination of abrasive and adhesive wear. High wear resistance was obtained in epoxy/OH-APS treated 30wt%MAf-20wt%BFSAp composites.
