Multiple Response Optimization of Three-Body Abrasive Wear Behaviour of Graphite Filled Carbon-Epoxy ComPosites Using Grey-Based Taguchi Approach

Abstract

The three-body abrasive wear behaviour of carbon fabric reinforced epoxy (C-E) composites has been evaluated by the addition of graphite (G) particles as a secondary reinforcement. Three-body abrasive wear test were conducted using dry sand rubber wheel abrasion tester as per ASTM G-65 with three process parameters load, abrading distance and filler content. To assess the abrasive wear behaviour of particulate filled C-E composites satisfying multiple performance measure, grey-based Taguchi approach has been adopted. The experiments were designed according to Taguchi's orthogonal array (L 27 ). The grey relational analysis was applied to convert a multi response process optimization to a single response. Using analysis of variance, significant contributions of process parameters have been determined. The results indicate that the addition of graphite particles into C-E composite increased the wear resistance considerably. It was observed that highest wear resistance of C-E composite was achieved with incorporation of 10 wt% of graphite filler. Results indicate that the filler content and grit size of abrasive paper were found to be the most significant factor which has influence on the abrasive wear of C-E composite. The worn surface features were examined through scanning electron microscope to probe the wear mechanism.

Tribological properties of carbon-reinforced epoxy composites - A review

“…Taguchi method was applied for wear behavior of polymer matrix composites [57,[108][109][110][111][112][113][114][115][116][117][118][119][120][121][122]. It can be seen that the grit size was pre-dominant parameter on the wear properties [109][110][111][112][113][114], followed by the load [12].…”

“…It was revealed that the effect of variables (PV) factor and filler content [116][117][118][119][120][121][122] was more pronounced on the sliding wear of glass-vinyl ester composites. Tribological property of 60 wt% carbon fabrics containing up to 5 wt% alumina nano particles fabricated by mixing method associated with compression molding method was investigated using a Taguchi method by taking into accounts of nano addition, load, speed and grit size [113].…”

Wear Characteristics of Hybrid Polymer Composite Manufactured by Hand Layup Technique Using Fuzzy Logic Systems

“…It was found that several fillers in epoxy coating considerably decrease its wear [1]. Threebody abrasive wear characteristic of carbon-epoxy composite with and without silicon carbide filler was studied by Subbaya et al [2]. They have used Taguchi L27 orthogonal array, by using grey relational analysis, carried out the experiments and optimized the process parameters.…”

Optimization of abrasive wear behaviour of halloysite nanotubes filled carbon fabric reinforced epoxy hybrid composites

“…The mechanical properties are augmented more with fibers when compared with other reinforcements. There are many researchers who investigated the potential of the fiber reinforcements like carbon fibers, glass fibers, and basalt fibers on the epoxy matrix in benefitting the tribological properties [9][10][11][12]. Suresha et al [9] have discussed that the carbon fiber composites are having better wear resistance than the glass fiber based epoxy composites.…”

“…Suresha et al [9] have discussed that the carbon fiber composites are having better wear resistance than the glass fiber based epoxy composites. Subbayya et al [10] have applied L 27 design and proved that the abrading distance, filler content and the load when considered individually have a higher significance and higher percentage of contribution than considered in combination. Ramesh and Suresha [13] have incorporated Taguchi, ANOVA and discussed that filler loading has the more influence than that of the normal load, under two-body abrasion also compared the relation between the sliding and abrasion wear.…”
