Effect of fibre content and combined effect of alkali and silane coupling agent treatments on tensile and impact properties of unidirectional roystonea regia natural fibre reinforced epoxy based partially bio degradable composites is reported. The reinforcement roystonea regia fibre was collected from the foliage of royal palm tree. To overcome the problems of poor fibre/matrix interface bonding, alkali and silane treatments have been applied to fibres to process the composites. Alkali treatment has been found to be more effective in improving the tensile properties than the silane treatment; however mixed treatment further slightly improved the properties. In general, the impact strength of all the treated fibre composites decreased compared to the untreated fibre composites; however, the silane treated fibre composites have shown higher impact strength followed by alkali treated fibre composites. Morphology of composites examined by scanning electron microscopy has also been reported. 14 Refs.
