Tribological behaviour of SiC and AL₂O₃ filled glass-epoxy composite

Abstract

Metal glass fibre reinforced composites which are considered as advanced composite materials play a significant role in aerospace, marine and automotive industries. In the current study, an attempt has been made to examine the tribological characteristics of glass fibre reinforced plastic (GFRP) composite filled with aluminium oxide (Al2O3) and silicon carbide (SiC) powder particles. Experiments were performed on pin-on-disc tribometer to evaluate the friction and wear rate as a function of normal load and sliding velocity under different conditions. For each composition of glass-epoxy composite filled with and without fillers, sliding tests were performed with normal load (20 N, 40 N, 60 N, 80 N 100 N) and sliding velocity (2.62 m/s, 4.18 m/s, 5.23 m/s, 6.85 m/s, 7.85 m/s) respectively. The metal GFRP composites were fabricated using hand-lay-up technique. The filler content (SiC & Al2O3) in epoxy-glass composite were varied. SiC was varied from 0 to 10% while Al2O3 was kept constant at 5%. To study the worn surface of glass-epoxy composite material scanning electronic microscopy is used. Before and after the experiment, weights of the composites (pin specimens) were studied on digital balance for wear loss. The present studies reported that the fabricated metal epoxy-fibre composite has performed excellent wear resistance when compared with epoxy-fibre composite without metal powders. The present work findings offer new insights into reinforcement in epoxy-glass composites with metal powders.

Effect of pistachio shell particles on mechanical and erosion wear performance of hybrid kenaf/glass polyester composites

“…Fillers are defined as inert substances which can improve the material performance and reduce material costs. 7 Fillers are also often used with matrix to achieve smooth surface finish, which would otherwise result in a rough texture that negatively affects the mechanical performance of the composites. 8 Hard fillers, in particular are effective in reducing wear rate, which enhances the tribological performance of the composites.…”

Tribological Properties and Lubrication Mechanisms of Water-Based Nanolubricants Containing TiO2 Nanoparticles during Micro Rolling of Titanium Foils

“…The utilization of nanoparticles in lubricants has attracted considerable attention owing to their potential to enhance the wear resistance and efficiency of mechanical systems [ 8 , 9 , 10 ]. Kumar et al [ 11 ] conducted a comprehensive review of nanolubricants and tribological behavior of the rolling process, highlighting the potential benefits of using nanoparticles in lubrication.…”
