“…Researchers proposed several solutions to solve or mitigate delamination-related problems [3][4][5][6][7][8][9]. Carbon nanofibers/nanotubes (CNFs/CNTs) proved to be the most effective solution in terms of mechanical reinforcement [10][11][12], but their difficult mixing process with the resin [13] and serious risks for human health [14] make them unsuitable in many cases. Polymers present several advantages compared to CNF/CNT, and the authors of present paper have a successful history of reinforcing composite laminates' interfaces using polymeric nanofibers [15][16][17][18], in particular Nylon 6,6 [19][20][21][22][23].…”

The benefits of interleaving polymeric electrospun nanofibers in between laminae of composite structure have been widely demonstrated in the past several years. Among the work that still has to be done, this paper aims to study delamination propagation of virgin and nanomodified specimens under Mode I fatigue loading. A 40-micron thick layer of Nylon 6,6 nanofibers have been produced and interleaved in carbon fiber-epoxy resin composite laminates; static and dynamic double cantilever tests have been performed to determine delamination growth onset and crack propagation rate vs. maximum energy release rate respectively. Nanomodified specimens exhibited improved delamination resistance during both the tests: delamination toughness increased 130% and cracks propagated 36 to 27 times slower than virgin interfaces. The benefits of the nanointerleave and its working mechanism have been explained using micrographs and SEM images, which revealed a double-stage reinforce mechanism

“…Eventually, it is also worth mentioning that other types of interleaves rose popularity in the last few years, such as CNF and CNT [80][81][82][83][84] but they are not treated in this review. The main issues with the use of CNT and CNF are linked to health dangerousness [85] and difficulties in mixing and homogenizing with the matrix [86]. Authors considered out of the scope of this literature, and therefore did not treat, studies on nanofibers embedded in pure matrix [60,[87][88][89][90][91][92][93][94], on the single nanofiber [95][96][97][98], and on numerical simulations of nanomodified composites [65,[99][100][101][102].…”

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.

“…In order to solve the above problem, numerous works with focus on processing and nanofiller factors that influence the mechanical properties have been reported. Extensive research has been conducted to investigate the effect of functionalization [17][18][19], dispersion [20,21], aspect ratio [22], acid treatment [23], heat treatment [24], plasma treatment [25] purification [26], and orientation [27,28] of CNFs as well as fabrication processes such as extrusion processing [29], spin casting [30], solution casting [31,32], in situ processing [7], and melt spinning [33] on the overall resulting properties of the polymer nanocomposites. However, there is still a very limited improvement in the mechanical enhancement in polymeric matrices as a result of the addition of such nanofillers [34].…”
