Enhancing Mechanical Properties of Natural Rubber Latex Composites through Alkali-Treated Areca Husk Fibers: Eco-Friendly Reinforcements

Abstract

This study explores the utilization of areca husk fiber (AHF), a naturally derived agricultural waste product, in enhancing the mechanical properties of natural rubber latex (NRL) composites. Areca husk fibers, treated with sodium hydroxide (NaOH) to improve their surface characteristics, were incorporated into NRL matrices. The objective was to investigate the effect of alkali treatment on the interfacial bonding and overall performance of the resulting composites. Mechanical testing revealed significant improvements in tensile strength, flexibility, and water resistance in the treated AHF composites compared to untreated ones. The findings suggest that alkali-treated AHF can significantly enhance the structural integrity and durability of NRL composites, offering a promising approach for developing sustainable, biodegradable materials from agricultural residues.
