This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/) Peer-review under responsibility of the VCSI1 organizers 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.

Nowadays, nanoparticles are applied in many engineering applications due to their unique surface effects, increased chemical activity and physical properties (Komarneni 1992; Ling and He 2004). In terms of mechanical (strength and stiffness) and thermal properties, for example, significant benefits are achieved by adding low concentra- Nowadays, n noparticles are applied in many engineeri g applicat ons due to their u ique ur ac effects, increased chemical activity and physical properti s (Komarneni 1992; Ling and He 2004).
