“…It is known that the fatigue failure of polymers and matrix‐dominated polymeric composites is more complicated than that of the well‐studied metals due to the viscoelastic response and the large plastic deformation capability of materials. Earlier researches focused on the experiments and theoretical analyses of the fatigue properties of various polymers,1–3 and more recently, there were more research reports about polymeric‐matrix composites 4–7…”

In this report, the fatigue behavior and lifetime of Polyimide/silica (PI/SiO 2 ) hybrid films are investigated. To evaluate the fatigue property of this class of hybrid films, the stress-life cyclic experiments under tension-tension fatigue loading with 10 Hz of the frequency are performed, and the stress ratio is 0.1. Dynamic creep and cyclic softening/hardening are analyzed based on the change of hysteresis loops during the fatigue process. The structure-property relations are discussed to further understand their phenomenon and deformation mechanisms. To predict the fatigue life of this class of hybrid films, a semiempirical model is proposed based on fatigue modulus concept. The simulated results are well agreeable with the testing values.
