In the last few decades nanofibers have been developed and introduced in a vast number of industrial and research applications. One of their most effective use is as interleaved reinforcement for composite laminate materials against delamination. Nanofibrous mats have the ideal morphology to be embedded between two plies of a laminate, and a vast and deep research has been carried out investigating their effect on the global behaviour of a composite laminate. This review is the first of its kind to date which presents a detailed state-ofthe-art on the effect of nanofibrous interleaves into composite laminates with focus on the mechanical performances and behaviours of nanomodified materials. A detailed description of the working mechanisms of the nanointerleave under different load cases is presented, and a comparative analysis between papers in literature will provide readers with a powerful tool to understand and use nanofibers for reinforcing purposes.

“…Our results are in good agreement with other results published previously. For example, the authors from [8] suggest that the damping of glass fiber composites increased by 36% due to the interleaving with nylon nanofibers. Other works, such as [26,27], found that the damping of composite laminates increased up to 28% and 108% because of the interleaving with jute nanofibers and carbon nanotubes respectively.…”

“…However, only several studies have investigated the vibratory behavior of composites reinforced with electrospun nanofibers. For example, the authors of [8] demonstrated that the incorporation of nylon nanofibers in glass fiber composite mats increases the damping ratio; however, it does not considerably affect the natural frequencies. Similar results were found in [9], where an important increase of the damping ratio in carbon fiber composite laminates due to the incorporation of nylon nanofibers is found.…”

In this article, the effect of polycaprolactone nanofibers on the dynamic behavior of glass fiber reinforced polymer composites is investigated. The vibratory behavior of composite beams in their pristine state (without any nano modification) and the same beams modified with polycaprolactone fibers is considered experimentally. The experimental results show that the incorporation of polycaprolactone nanofibers increases the damping; however, it does not significantly affect the natural frequencies. Additionally, the paper analyses the effect of polycaprolactone nanofibers on the impact behavior of glass fiber/epoxy composites. This has already been analyzed experimentally in a previous study. In this work, we developed a finite element model to simulate the impact behavior of such composite laminates. Our results confirm the conclusions done experimentally and prove that composites reinforced with polycaprolactone nanofibers are more resistant to damage and experience less damage when subjected to the same impact as the pristine composites. This study contributes to the knowledge about the dynamic behavior and the impact resistance of glass fiber reinforced polymer composites reinforced with polycaprolactone nanofibers. The findings of this study show that interleaving with polycaprolactone nanofibers can be used to control the vibrations and improve the impact damage resistance of structures made of composite mats as aircrafts or wind turbines.

“…The modified variational principle was used for the derivation of the formulation, and a multi-segment partitioning strategy was employed. The vibration characteristics of glass fiber-reinforced polymer (GFRP) composites reinforced with nylon nano-fibers were experimentally and numerically studied by Garcia et al [18,19]. Recently, the spectral-Tchebychev technique, which utilizes Tchebychev polynomials for the spatial discretization, has been proposed by several researchers [20][21][22].…”

Free Vibration Analysis of Curved Laminated Composite Beams with Different Shapes, Lamination Schemes, and Boundary Conditions

et al. 2020

A general formulation is considered for the free vibration of curved laminated composite beams (CLCBs) with alterable curvatures and diverse boundary restraints. In accordance with higher-order shear deformation theory (HSDT), an improved variational approach is introduced for the numerical modeling. Besides, the multi-segment partitioning strategy is exploited for the derivation of motion equations, where the CLCBs are separated into several segments. Penalty parameters are considered to handle the arbitrary boundary conditions. The admissible functions of each separated beam segment are expanded in terms of Jacobi polynomials. The solutions are achieved through the variational approach. The proposed methodology can deal with arbitrary boundary restraints in a unified way by conveniently changing correlated parameters without interfering with the solution procedure.
