Abstract: The chemical, impact, tensile properties of Bamboo/Grass/Onion fibres reinforced polyester hybrid composites were studied. The effect of alkali treatment for Bamboo/Grass/Onion fibres on these properties was also studied. It was absorbed that tensile properties of hybrid composites increase with bamboo fibre content. These properties found to be higher when alkaline treated bamboo fibres were used in the hybrid composites. The elimination of amorphous hemi – cellulose with alkali treated leading to higher crystallinity of the bamboo fibres with alkali treatment may be responsible for these observations. The effect of alkali treatment on the bonding between Bamboo/Grass/Onion fibres was also studied. The chemical resistance of Bamboo/Grass/Onion reinforced polyester composites to acetic acid, nitric acid, hydrochloric acid, sodium hydroxide, sodium carbonate, benzene, toluene, carbon tetrachloride and water was studied. The bonding between fibres and matrix was studied by metallographic (Scanning Electron Microscope) analysis
