ResumoIn this study, the impact of natural fibers (NFs) on the mechanical, thermal and hydrodegradation behavior was assessed. Composites based on biobased high-density polyethylene were manufactured with a 40 wt% of wood flour, basalt fibers, flax fibers, and walnut shell flour. The results confirmed the reinforcing effect of NFs on mechanical properties, especially in relation to the stiffness of the composites. Significant improvement was visible in the case of composites with basalt fibers with about 600% and 156% improvements for Young's modulus and tensile strength, respectively. Moreover, to evaluate the viability of NFs as reinforcements, water absorption and its influence on mechanical properties were investigated. Unmodified polymer and composites with basalt fibers showed similar relationships – low water absorption. Composites reinforced with lignocellulosic fibers exhibited high water uptake and progressive deterioration of properties over time.
