Résumé

Continuous-fiber reinforced WPCs were prepared using an extruder with a special die. The effects of the amount (1–7 bundles) and type of fiber (aramid rovings and yarns and carbon and glass yarns) on the mechanical properties of WPCs were studied. The addition of continuous fibers increased the tensile, flexural and impact strength of the composites by up to 47.3%, 83.1% and 713.4%, respectively. The damping ratio analysis revealed that the interfacial bonding of glass-yarn reinforced WPCs was the best among the tested samples. Adding continuous fibers to WPCs at a low volume fraction can promote their use as load-bearing engineered materials.
