Hydrothermal Aging Behavior and Tensile Properties of Olive Stone Flour-Reinforced High Density Polyethylene Bio-Composites

For environmental causes, bio-composites are gradually increasing. The main difficulty with these materials is their resistance to moisture absorption which limits their longevity. This study investigated the behavior of High Density Polyethylene /Olive Stone Flour (HDPE/OSF) bio-composites immersed in distilled water and sea water at three different temperatures then compared to neat HDPE. The absorption rate was increased for the charged composites compared to the neat material. Nevertheless, the rigidity of the aged composites remains slightly higher than the aged neat HDPE.
