Natural fibre composites, due to their biodegradable and eco friendly nature, are being explored for potential application in wide areas. But their strengths need to be enhanced. Hybridization of the natural fibres with incorporation of nanofillers helps to tailor the properties of nanofillers, and individual fibers and enhance the properties of resultant composite. The present work aims to explore the mechanical propertis of jute-basalt hybrid composites by incorporating graphene nanofillers of varying concentrations. Basalt, jute and jute-basalt hybrid composites with varying concentrations of graphene (0 wt%, 0.2 wt%, 0.4 wt%, 0.6 wt%, 1 wt%) are prepared. Effect of hybridization of different fibers and influence of graphene on mechanical properties are analyzed. The effect of nature of top and bottom laminates on mechanical properties is also observed. Maximum improvement in tensile strength, flexural strength and hardness is found to be 13 %, 29 % and 55 %, respectively, with hybrid composite containing 1 wt.% graphene compared to hybrid composite without graphene. Impact strength is found to be highest for hybrid composite containing 0.4 wt.% graphene with 17 % increase compared to hybrid composite without graphene.
