Abstract
A novel combination of Borassus Flabellifer Petiole Fibre/Palmyra Palm Petiole Fibre (PP) and Borassus Flabellifer Leaf Stalk Fibre/Palmyra Palm Leaf Stalk Fibre fibres (LS) bonded by vinyl ester is considered as the natural fibre-reinforced hybrid composites. Three-layered composites with various stacking sequences at 30 wt.% fibre loading were studied. Tensile, impact, and hardness properties exhibit increasing trend for different stacking sequences. A maximum increase of 215.8% tensile strength and 310.5% impact strength was observed in the PPLSPP (90/0/90) specimen. The water absorption percentage showed a peak value of 18% and the hardness enhancement was around 75% for the LSPPLS (90/0/90) sample. The Fourier Transform Infrared spectroscopy was performed and Scanning electron micrographs were performed to show the fibre–matrix bonding.
