Abstract Wood fiber reinforced polyamide 6 (PA6) and high‐density polyethylene (HDPE) blend composites were prepared via hot pressing. The PA6 was modified by lithium chloride (LiCl) for reducing the melting point. Crystallization analysis exhibited the decrease of the melting point (220°C to none) and the processing temperature (240°C to 200°C) of PA6. Thus, undesired discoloration and degradation were improved. LiCl was in favor of the interfacial compatibility among PA6, HDPE, and wood fiber. Also the LiCl could enhance the mechanical properties of the final products. The maximum flexural strength can reach up to 100.4 MPa. Besides, both maleic anhydride grafted high‐density polyethylene and wood fiber had positive effects on the mechanical performance.
