abstract The article aims to study the impact of date palm powder (DPP) on the mechanical and thermal characterizations of a high- -density polyethylene (HDPE) matrix. HDPE composites enhanced with ratios varying from 5 to 20 wt.% DPP were produced by means of a twin-screw extruder. The results indicate that incorporating between 5 to 20 wt.% DPP in pure HDPE led to an increase in the tensile strength and Young’s modulus, while the elongation at break decreased. Furthermore, the results of thermal gravimetric analysis (TGA) revealed that incorporating DPP into pure HDPE improved the thermal stability owing to a reduction in the interfaces between DPP and the pure HDPE matrix, resulted in brittle behavior, and enhanced the great crosslinking of pure HDPE.
