This work studies the fatigue behavior of biodegradable composites of thermoplastic starch (TPS) reinforced with different amounts of date palm fibers (DPF) (20, 50, and 70 wt%). Composite with 50 wt% fiber content had higher static and fatigue strengths compared to other composites. The alternating stress at which the composites lasted for 10 7 cycles was about 16% of the flexural strength. Mathematical models following the assumptions of D’Amore et al. (1996) and Mao and Mahadevan (2002) were shown to give a good agreement with experimental results of the residual strengths under various fatigue cycles and of the fatigue damage index at different levels of stresses.
