Abstract: The performance and behaviour of various natural fibres and their hybrids with synthetic glass fibre composites were investigated in this work. The composites were fabricated using moulding method. The tensile compressive and flexural strength of the fabricated composites were tested using universal testing machine (UTM). From the load-displacement graph obtained from UTM, the effect of fibres and its hybridisation with glass fibre on the ultimate stress and the displacement on loading were analysed. The impact strength of the un-notched composites was analysed using charpy impact tester. The water immersion tests were also conducted to ensure the weathering behaviour/suitability of this moulded composite under some moisture conditions. From the experimentations it was concluded that the natural fibres can become a best competitor to eliminate or decrease the use of conventional fibre reinforcement. In general, the hybridisation of natural fibre composites enhances the mechanical properties.
