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.

“…• nanofiber bridging [14,25,29,37,38,46,68,69], mostly found when using ductile PA nanofibers. The phenomenon is well presented in [29], where authors present a detailed analysis of the fracture surface of their tested samples, using SEM: an extensive interlaminar crossings have been observed, besides the usual glass fiber-epoxy debonding.…”

“…It consists mainly of Mode I and Mode II interlaminar fracture tests performed on interleaved laminates under static conditions [14,20,[24][25][26][27][28][29][30]. Although these experiments provide useful information about critical parameters, toughening (micro)mechanisms and general concerns of the delamination behaviour in nanofibre interleaved laminates under static conditions, an analysis of the effect of nanofibrous interleaves under fatigue loadings has not been reported in literature to date.…”

“…Nanofibrous veils are electrospun from polycaprolactone (PCL), polyamide 6 (PA 6) and polyamide 6.9 (PA 6.9) since these systems have proven their effectiveness under static loading conditions [14,27,34]. The focus is on Mode II delamination behaviour as delamination growth during service often occurs under Mode II dominated loadings.…”

“…One of the methods to prevent delamination is the introduction of nanofibers into epoxy-based composite laminate materials [1]. Composites interleaved with nanofibers are supposed to increase their delamination resistance as compared to the virgin ones [2]. The interleaving with nano-fibers can be also used to increase the stiffness and other macro-properties of epoxy-based composite laminates.…”

Abstract. Vibrations are responsible for a considerable number of accidents in aircrafts, bridges and other civil engineering structures. Therefore, there is a need to reduce the vibrations on structures made of composite materials. Delamination is a particularly dangerous failure mode for composite materials because delaminated composites can lose up to 60% of their strength and stiffness and still remain unchanged. One of the methods to suppress vibrations and preventing delamination is to incorporate nanofibers into the composite laminates. The aim of the present work is to investigate how nylon nanofibers affect the dynamic behaviour and delamination resistance of glass fibre reinforced polymer (GFRP) composites. Experiments and numerical simulations using finite element modelling (FEM) analysis are used to estimate the natural frequencies, the damping ratio and inter-laminar strength in GFRP composites with and without nylon nanofibers. It is found that the natural frequencies of the nylon nano-modified composites do not change significantly as compared to the traditional composites. However, nano-modified composites demonstrated a considerable increase in damping ratio and inter-laminar shear strength due to the incorporation of nylon nanofibers. This work contributes to the knowledge about the mechanical and dynamic properties of glass fibre reinforced polymer (GFRP) composites with nylon nanofibers.
