Abstract

Thermosetting epoxy polymer reinforced with continuous fibers, well known as fiber-reinforced polymer (FRP) composites are extensively used in structural applications because of their high specific strength and stiffness. Structural components made from FRP composites experience fatigue loads in service and hence, possessing high fatigue life is one of the important requirements in these materials. Recent efforts made to enhance the fatigue properties of FRP composites by incorporating micro and nano-sized fillers in the epoxy matrix have led to some promising results. Composites containing nano-sized fillers in the epoxy, known as polymer nanocomposites are gaining importance from the viewpoint of enhanced mechanical properties. The presence of nano fillers improve the fatigue life of pure epoxies and also FRPs with nano-modified epoxy matrix. Parameters such as nanofiller type, size, shape, volume fraction and uniformity of dispersion in the epoxy, influence the fatigue properties of nanocomposites significantly. In this paper, the effect of various types of nano fillers on the fatigue life of bulk epoxies and FRPs is briefly reviewed. The mechanisms for observed enhancements in fatigue properties and fatigue behavior under spectrum fatigue loads are also discussed. Effect of environment on the fatigue behavior of nanocomposites is briefly highlighted. The current limitations and the future course of research required are also highlighted.
