Abstract

This study investigated chemical treatment’s impact on mechanical and flammability properties of rice husk-reinforced recycled high-density polyethylene (r-HDPE) composites. Three treatments (maleate, alkali, acid) were applied to rice husk, and composites were tested for tensile strength, elongation at break, and modulus of elasticity. Results showed that tensile strength decreased with increasing rice husk content, except for composites treated with maleic anhydride grafted polyethylene (MAPE), which exhibited the highest strength at 10% filler content. Break elongation generally decreased with increased rice husk content, while the modulus of elasticity improved with higher rice husk content, except for acid-treated composites. Scanning electron microscopy revealed better interfacial bonding in composites with lower rice husk loading. Maleate treatment enhanced flame resistance. In conclusion, chemical treatment has the potential to enhance the properties of rice husk-reinforced r-HDPE composites for various applications.
