Abstract

Lignocellulose fllers, like cotton stalks, provide a stifness that enhances the mechanical properties of composites. However, fnding an appropriate fller loading for optimizing the mechanical performance of biocomposites remains a challenge, as there are disparities in the optimum fller loadings found in previous studies concerning the use of cotton stalk as a fller in biocomposite manufacturing. Therefore, the need for further investigations is of prime importance. Cotton-stalk-fller-reinforced high-density polyethylene (CS/HDPE) biocomposites were fabricated with diferent weight proportions (10-50 wt%) of the cotton stalk fller with particle size distributions 425 to 53 μm. The biocomposites were prepared using an extrusion process with a twin-screw extruder followed by compression molding in an electrically heated platen press. Results showed that the composite reinforced with 50 wt% fller gave the optimum values of tensile and fexural moduli.
