Linear low density polyethylene (LLDPE) was reinforced with wood fiber, glass fiber, and mica. The effect of aging on mechanical properties of the composites was examined under different conditions: (i) exposure at 105°C for 7 days; (ii) immersion in boiling water for 4 h. Samples containing glass fibers showed by far the best results with regard to tensile strength, elongation, and fracture energy. LLDPE filled with mica produced poor results compared to wood fiber composites. Dimensional stability of LLDPE–wood fiber composites, after boiling water treatment, was inferior to mica and glass fiber composites.
