| The awareness amongst the researchers to develop an environment friendly sustainable material leads to explore new class of plant-based fiber for making composites. Hybridization of such plant-based fiber with inclusion of engineered fiber is one of the promising methods to not only enhanced the mechanical performance but also suppressed the drawbacks that associate with such plant-based fiber to some extent. A usual hand lay-up method was taken-up in this work to fabricate four layered of hybrid kenaf(K)/glass(G) polyester laminates with different stacking order such as KKKK, KGKG, KGGK, GKKG and GGGG. The erosive character of the laminates was examined under three distinct particle velocities (48 m/s, 70 m/s, 82 m/s) and four different impact angles (30o, 45°, 60o, 90°). All fabricated laminates exhibited a semi-ductile character at lower velocities (48 m/s and 70 m/s) as peak wear rate was observed at 45° impact angle. However, they showed a semi-brittle character at high velocity (82 m/s) as maximum rate of erosion was noticed at 60o impact angle. Again, the influence of stacking order of piles on erosion wear was also clearly noticed. Moreover, the semi-brittle/semi-ductile characterization was also evidenced in accordance to the range of erosion efficiencies. The micro-structures of worn surfaces were inspected thoroughly from the images of scanning electron microscope (SEM) to evident the mechanism of erosion. |
