Fatigue behaviour of graphene composites: An overview

In recent years, there has been a rapid growth in the use of composite materials in engineering applications, and this evidence should continue. However, the desire and necessity to improve the efficiency of these materials for engineering applications more ambitious have led to use of several nano-sized fillers. In fact, nanoparticles with typical dimensions in the range between 1 and 100 nm have been widely studied due to their unique surface effect, increased chemical activity and physical properties. From all nanofillers studied to improve the mechanical performance of composite materials, graphene is the latest and promising nano reinforcement due to its unique mechanical properties combined with its good electrical performance. Therefore, this work intends to develop a short review about the benefits of the graphene fillers on the fatigue strength, especially in terms of polymeric resins, elastomers and composites. This subject is very important, because fatigue failures can lead to tragic consequences. It was possible to conclude that the presence of this filler improves the fatigue strength, but the knowledge is not yet enough to establish a complete understanding of this subject.
