Evaluation of three body abrasive wear behavior of bidirectional jute fiber reinforced epoxy composites

Abstract

The need of eco-friendly, sustainable, and biodegradable material for structural and nonstructural application increases day by day. Jute fiber is one of the largely produced natural fibers and has properties comparable to synthetic fibers. Currently, abrasive wear of the agricultural and engineering machine components is one of the major industrial problems. An attempt has been made in this paper to study the abrasive wear behavior of bidirectional jute fiber-epoxy composites. Composites of five different compositions with fiber loading ranging from 0 to 48 wt.% were prepared using hand lay-up technique. Observations has been made under steady state condition to understand the effect of sliding velocity and normal load on the specific wear rate and coefficient of friction of the composites. It further outlines a methodology based on Taguchi's experimental design approach to make a parametric analysis of wear behavior. It has been found that the composites with 36 wt.% fiber loading exhibits minimum specific wear rate at different sliding velocity and normal load. The parametric combination of factors, such as sliding velocity of 144 cm/s, fiber loading of 48 wt.%, normal load of 40 N, sliding distance of 70 m, and abrasive size of 200 mm shows an optimum condition for minimum specific wear rate, whereas sliding velocity of 144 cm/s, fiber loading of 12 wt.%, normal load of 10 N, sliding distance of 80 m, and abrasive size of 300 mm show an optimum condition for minimum coefficient of friction. Finally, the worn surfaces were examined using a scanning electron microscope.

Investigation of mechanical and abrasive wear behavior of blast furnace slag‐filled needle‐punched nonwoven viscose fabric epoxy hybrid composites

“…The main aim of this study was to characterize the morphology of abraded surfaces and to recognize the mode of material removal. SEM observations reported previously reveal that the abrasive wear of the polymer composites in particular is a complex process involving matrix micro‐cracking, ploughing, micro‐cutting, fiber breakage, and so on .…”

Assessment of mechanical and three-body abrasive wear peculiarity of TiO2- and ZnO-filled bi-directional E-glass fibre-based polyester composites

“…Figure 10 shows the variation of specific wear rate with normal load under steady-state conditions for TiO 2 -and ZnOfilled E-glass fibre-polyester composites at sliding speed of 0.5 m s −1 and figure 11 shows same at sliding speed 1.0 m s −1 . It is observed that specific wear rate increases with increase in the load [35]. The unfilled composite exhibits highest wear rate for all load conditions for each sliding Figure 12 shows the variation of specific wear rate with sliding distance under steady-state conditions for TiO 2 -and ZnO-filled E-glass fibre-polyester composites at normal load of 4 N. Figure 13 shows same at normal load of 12 N. It is found that at small sliding distance, unfilled E-glass fibrereinforced composites exhibit highest specific wear rate and the same phenomenon is shown among all the sliding distances.…”

Preparation of silica‐decorated graphene oxide nanohybrid system as a highly efficient reinforcement for woven jute fabric reinforced epoxy composites

“…[1,2] Among these materials, jute fibers (JF) have attracted considerable attention for the fabrication of fiber-reinforced composites. [3][4][5][6][7] A plethora of reports are available in the literature on JF-reinforced polymers and their properties. Dilfi et al [3] investigated the influence of fiber surface modification on the mechanical behavior of JF-reinforced epoxy composites.…”

“…Raghavendra et al [4] compared the tribological properties of epoxy composites reinforced with jute and glass fibers and showed that the jute fiber/epoxy specimens had superior properties than glass-reinforced epoxy composites. Militky et al [5] explored the creep behavior of treated JF/epoxy (EP) composites. It was shown that the treated composites had less creep strain than untreated one at all temperatures.…”
