Effect of alkali treatment on mechanical properties of pineapple leaf fiber/polyester composites by vacuum infusion method

This study investigates the effects of fiber treatments on mechanical properties pineapple leaf reinforced polyester composites (PALF/PE). The Fiber were conducted with 3%, 6% and 9% NaOH for 2 hours. untreated treated PALF/PE fabricated by vacuum infusion method. result analysis revealed that indicated an increasing pattern in compared to composites. highest tensile strength was112 Mpa at 6 % impact was 0.11891 Joule/mm2 NaOH. Moreover, fracture images indicate relatively less pull-out improved fiber/matrix adhesion. would be promising construction, furniture automotive materials due their superior properties.
