“…For glass and carbon fiber‐reinforced polymer composites, it is significant to infuse polymer into each and every fiber tow. If polymer is not able to infuse well, voids could be introduced, resulting in a degradation of the mechanical properties 17,28,30 . A series of experiments were conducted to increase the wettability of nanofibers and bubble‐free nanocomposite films.…”

This study deals with the fabrication of a novel polyketone nanofiber‐reinforced UV‐curable polyurethane acrylate nanocomposite. An aliphatic polyketone nanofibrous mat was proficiently prepared by electrospinning using a solvent mixture of methylene chloride and trifluoroacetic acid. The outstanding characteristics of polymer nanofibers including a small pore size, a high aspect ratio and molecular orientation and an excellent mechanical performance offer the use of nanofibers as reinforcement in making nanocomposites. We fabricated a novel highly transparent and flexible nanocomposite film based on casting, electrospinning and UV‐curing processes. This method allowed significant enhancement of the mechanical properties using a very small amount (approximately 3.5 gsm) of polyketone nanofiber. The yield strength and Young's modulus of the nanocomposite were improved by up to 61% and 60%, respectively, compared to a UV‐cured polyurethane acrylate film. The reinforcing effect of nanofibers was accomplished without sacrificing the transparency and flexibility of polyurethane acrylate. The morphologies of the nanofibers and fiber–resin interface as well as the characteristics of the nanocomposite films were also studied. The effective use of nanofibers as a reinforcement and the preparation of a nanocomposite along with its characterization in comparison to a UV‐cured polyurethane acrylate film are also discussed. © 2020 Society of Chemical Industry

“…The results showed that nanofibers could increase the adhesion strength between AL and laminate, which led to a decrease of the damaged area between 42% and 62% depending on the impact energy level ( Figure 5). Anand et al [30] used a new method for producing nanomodified laminates. In this method, the nanofibers were firstly electrospun on dry glass fibers, then cast resin film was transferred to them.…”

This paper reviews recent works on the application of nanofibers and nanoparticle reinforcements to enhance the interlaminar fracture toughness, to reduce the impact induced damage and to improve the compression after impact performance of fiber reinforced composites with brittle thermosetting resins. The nanofibers have been mainly used as mats embedded between plies of laminated composites, whereas the nanoparticles have been used in 0D, 1D, 2D, and 3D dimensional patterns to reinforce the matrix and consequently the composite. The reinforcement mechanisms are presented, and a comparison is done between the different papers in the literature. This review shows that in order to have an efficient reinforcement effect, careful consideration is required in the manufacturing, materials selection and reinforcement content and percentage. The selection of the right parameters can provide a tough and impact resistant composite with cost effective reinforcements.

“…High performance thermoplastics with high modulus and high glass transition temperatures have been reported to be efficient in improving the fracture toughness of laminated composites [27][28][29][30][31][32][33][34]; they can be cured and implemented during the manufacturing process of the laminated composites [35]. One of the constraints of these interleave materials is the requirement of a good chemical and physical compatibility between the interleaving thermoplastic and the bulk thermoset resin.…”

A tough polyethersulfone (PES) membrane was utilized as a novel reinforcement to improve impact performance of a carbon/glass hybrid composite. The hybrid composite was made of a glass fibre/epoxy block that was sandwiched between two carbon fibre/epoxy blocks. The PES reinforced hybrid composite was compared with an unmodified hybrid composite and a glass reinforced aluminium (GLARE) laminate. During impact testing, results showed that incorporation of PES led to an increase in toughness with a reduction in damage propagation in the investigated composite panels. Furthermore, the results showed that for low impact energy levels (6 J, 12 J and 18 J), the addition of the PES membrane reduced the area of damage by an average of 67%, compared to the virgin laminate. By increasing the impact energy level (24 J and 32 J), fibre breakage was the dominant failure mode and the PES had a negligible effect on the impact performance. A comparable load bearing performance was observed with the hybrid composites and the GLARE laminate for the low energy levels (6 J, 12 J and 18 J). However, the GLARE laminate had a better performance during high energy impacts (24J and 32 J), due to the high ductility of the aluminium plates.
