“…Other authors found similar results for nylon nano enriched composites: A similar effect was observed in [17] which investigated the impact resistance under low velocity impact of nylon nanofibrous modified composite laminates. This work found that damping ratio of carbon fibre composite panels reinforced with nylon nanofibers is about 62% higher than the damping of virgin panels.…”

“…Although some authors have studied the dynamic behaviour of nano-enriched composites mainly based on experimental method [17][18], there is currently very little information on the effect of nylon nano-fibrous enrichment and its effect on the global/macro dynamical properties of the enriched structures. Some of the authors of this study previously investigated some effects of the inclusion of nylon layers in carbon-fibre composites [17].…”

“…Some of the authors of this study previously investigated some effects of the inclusion of nylon layers in carbon-fibre composites [17]. [17] is a completely experimental study and the authors concentrated on the effect of the nano-layers when they are interleaved in different places. It was focussed primarily on the energy dissipation of the nano-enriched specimens and their resistance to impact.…”

The vibration behaviour of GFRP composites reinforced with nylon nano-fibres is considered experimentally and numerically using a finite element model. The present analysis of clamped-clamped beams investigates the natural frequencies, the damping and the stiffness of virgin and nano-interleaved composite laminates. The numerical modelling uses ANSYS Workbench 16.2. Experimental and numerical results showed a significant effect of the nylon nanofibers on the dynamic behaviour of the composites. Nano-modified composites demonstrated a consistent increase in the damping ratio and inter-laminar strength. However, the variation in natural frequencies and stiffness due to the nanofibers was very small. This study contributes to the knowledge about the macro dynamic properties of nylon interleaved GFRP composites. It demonstrates that a simple FE model can be used to accurately predict the dynamic behaviour of such nano-composites.

“…Theoretically, by adjusting the thickness of the interleaves and choosing the appropriate nanofiber material the properties of the composite can be tailored from rigid to tough kind of damage. This effect was demonstrated experimentally for Nylon 6.6 interleaves in [16,17]. The toughening effect of polyacrylonitrile (PAN) nanofibrous interleaves in carbon fiber-reinforced structures was proved in [18].…”

Abstract. The present paper investigates how the presence of nanofiber interleaves affects the compressibility of the layup during manufacturing of the composites and hence determining the theoretically attainable fiber volume fraction at the given processing pressure. The results show that up to the interleave areal density of 10 g/m 2 per nanofiber layer the decrease of fiber volume fraction does not exceed 3% for a laminate of carbon fiber woven fabric. Interleaves inside a fabric laminate are more compressible than a plain electrospun veil. It can be explained as the nanofibers penetrate between the carbon fibers when applying compression during composite manufacturing. It can be stated that there is a strong interference between the interleaves and the carbon reinforcement, which can lead to effective toughness improvement of the composite without significant alteration of fiber volume content.

“…According to these results, it can be concluded that the incorporation of nanofibers has a significant impact on the interlaminar strength. According to [14], the increase in interlaminar strength can be explained with the presence of significant bridging phenomena due to the interaction between the epoxy resin and the nylon nanofibers…”

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.
