Abstract
An effort has been made in the current research to analyse the influence of alkali and saline treatments on the mechanical properties of Roystonea-regia (RR)/banana (BA) fibre reinforced hybrid polyester composites. Composites were prepared using both treated and untreated fibres using hand layup technique. Total reinforcement content in the hybrid composites was limited to 15 wt%. Prepared specimens were tested for tensile, flexural and impact properties as per ASTM standards. Highest tensile and flexural properties were obtained for the composites reinforced with 5 wt% RR fibres and 10 wt% of BA fibres for both treated and untreated conditions. Alkali treated specimens exhibited superior tensile and flexural properties in comparison to untreated and silane treated specimens. However, composite reinforced with untreated fibres showed better impact strength.
