Erosive wear behavior of ecofriendly hybrid composite

Abstract

This study investigated the potential of Basalt–Jute hybrid composite as a reinforcement material in erosive wear-prone applications. It examines solid particles’ effect on the erosion wear behavior of a new natural fiber composite made with basalt and jute. The composite was prepared with different stacking sequences using the hand layup technique. Erosion wear was conducted with an air jet erosion test as per ASTM G76 standards, using four impact angles (30°, 45°, 60°, 90°) and three velocities (48 m/s, 70 m/s, 82 m/s). Results show that the maximum erosion wear rates observed at velocities 48 m/s and 70 m/s are 2.63 × 10⁻⁴gm/gm and 7.22 x10⁻⁴gm/gm, respectively, at 45^o impact angle for BJBJ composite, while at 60^o impact angle and 82 m/s, it was 11 × 10⁻⁴ gm/gm. The stacking sequences—JBBJ and JBJB prove to be the better options for high-erosive environments. The results demonstrated that JBJB exhibited the lowest erosion rate of 1.11 × 10⁻⁴gm/gm of all hybrid composites, showing the effect of stacking sequence on erosion rate. It was observed that maximum erosion wear rates occurred for most of the composites at 45^o impact angle. However, this trend shifted towards 60^o impact angle at a higher velocity of 82 m/s. These observations show a largely semi-ductile to feeble semi-brittle nature of erosion for the chosen hybrid composites. The study showed that the Basalt–Jute hybrid composite could be a better candidate in wear-prone applications for an impact angle range of 45^o–60^o at lower and 60^o–90^o at higher velocities.
