Study on physical and mechanical properties of NFRP hybrid composites

The tensile, flexural, impact properties and water absorption tests were carried out using sisal/unsaturated polyester composite material. Initially, optimum fiber length and weight percentage were determined. To improve the tensile, flexural, impact properties, sisal fiber was hybridised with bamboo fiber. This work showed that addition of bamboo fiber in sisal/unsaturated polyester composites of up to 50% by weight results in increasing the mechanical properties and decreasing the moisture absorption property. Morphological analysis was carried out to observe fracture behaviour and fiber pull-out of the samples using scanning electron microscope.
