Solid Particle Erosion of Date Palm Leaf Fiber Reinforced Polyvinyl Alcohol Composites

Abstract

Solid particle erosion behavior of short date palm leaf (DPL) fiber reinforced polyvinyl alcohol (PVA) composite has been studied using silica sand particles (200 ± 50 μm) as an erodent at different impingement angles (15–90°) and impact velocities (48–109 m/s). The influence of fiber content (wt% of DPL fiber) on erosion rate of PVA/DPL composite has also been investigated. The neat PVA shows maximum erosion rate at 30° impingement angle whereas PVA/DPL composites exhibit maximum erosion rate at 45° impingement angle irrespective of fiber loading showing semiductile behavior. The erosion efficiency of PVA and its composites varies from 0.735 to 16.289% for different impact velocities studied. The eroded surfaces were observed under scanning electron microscope (SEM) to understand the erosion mechanism.

Implementations of the Taguchi design for the erosive wear of Luffa cylindrica fiber-reinforced epoxy hybrid composite

“…The highest values of the erosion efficiencies of laminate stacking sequence S1 indicate poor erosion resistance. Similar observations on erosion efficiency for different polymer composites have also been reported by different investigators [14,30]. Hence, we can conclude that the erosion resistance of the L. cylindrica epoxy composite can be improved by hybridizing it with glass fiber.…”

“…Mishra and Acharya [11], Deo and Acharya [12], and Gupta et al [13] have reported the tribopotential of sugarcane, Lantana cammara, and bamboo fiber reinforcements in thermoset polymers for enhancing erosive wear resistance. Recently, Mohanty et al [14] and Ojha et al [15] studied the erosive wear behaviors of date palm leaf fiber-reinforced polyvinyl alcohol composites and wood apple shell fiber-reinforced epoxy composites.…”

A Review of Natural Fiber Reinforced Poly(Vinyl Alcohol) Based Composites: Application and Opportunity

“…On the other hand, some researchers applied chemical treatment on the natural fibers as an alternative approach to improve the mechanical properties of the composites [50,51]. Acid such as acrylic acid was reported to be able to treat the date palm leaf fibers.…”

Experimental Evaluation of Erosion of Gunmetal under Asymmetrical Shaped Sand Particle

“…Brittle materials, on the other hand, show maximum erosion under normal impingement angle (90 ∘ ). Some materials have been shown, however, to exhibit a semiductile behavior with maximum erosion occurring in the angular range 45-60 ∘ [22][23][24]. However, the above classification is not absolute as the erosion behavior of metals and alloys but in reality it strongly depends upon the experimental conditions and mechanical and chemical properties of target materials.…”

“…In the literature, there are no fixed trends of correlating ductility or brittleness of materials with max or min . It is found that some target materials are characterized in a ductile manner; on the other hand, some show evidence of both ductile and brittle characteristics [23,[25][26][27]. Nonferrous materials generally exhibit a more ductile response than ferrous materials [28].…”
