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(30°,45°,60°,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 60° 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.
