This work is carried out to find out the erosion wear characteristics of unfilled and also SiC nanopowder filled flax and sisal fabric hybrid composites (FSHC). Effect of different parameters such as filler content, impingement angle and erodent size on the erosion wear behavior of hybrid composite has been studied using Taguchi method. Significant control factors altering the erosion rate have been evaluated through outstanding execution ANOVA. The experimental outcomes are recognized to be in acceptable accord with the assumptive values. This study indicates that erosion wear resistance increases as SiC nanopowder increases in FSHC

Natural fibre-reinforced polymer composites are standing in the limelight of investigations due to their light weight and availability from natural and renewable resources. Improved mechanical and physical behaviour is targeted through hybridisation with other reinforcing elements. This study investigates the potential of adding silicon carbide particles at volume contents ranging between 2 and 8% to jute fabric-reinforced epoxy composite to produce such hybrid composites. In contrast to the commonly applied processing technique of hand layup used to produce natural fibre-reinforced laminates, the vacuum-assisted resin infusion method was applied in this study to produce high quality laminates. Samples were tested for their mechanical behaviour through tensile, flexural and impact tests. Scanning electron microscopy was further performed to analyse the modes of failure of the composites. Finally, erosion tests were conducted, by directly sanding the hybrid composite samples to evaluate their erosion wear resistance. Results indicated that the addition of particles had a significant effect on the tensile, flexural, impact and erosion wear behaviour of the composites under investigation. Hybrid composites reinforced with 4 vol.% SiC exhibited acceptable mechanical properties. The behaviour was found to deteriorate at SiC contents beyond 4 vol.%.
