“…In [50] it is showed that tensile properties of UD GFRP laminates are not affected by the presence of PCL nanofiber; in [30], it is shown that PA6 nanofibers caused an increase of stress at failure of the composite of about 6% and 11% when the nanofibers were added during layup and when directly deposited onto the fabric, respectively. A unique use of Silk has been presented in [69], showing a 5% improved tensile strength. The main evidence of the reinforcing mechanisms of a nanointerleave in tensile tested specimens is provided in [113].…”

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.

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.…”

“…6 The use of CSR particles diminishes the possibility of incomplete phase separation which occur in case of liquid rubbers which hampers the properties like glass transition temperature (T g ) and elastic modulus. 21 Many authors have studied the use of filler particles such as silica (SiO 2 ) 22,23 silk fibroin, 24 bamboo fibrils, 25 and glass. 7 The modification of epoxy by BCP can be benefited from the ability to obtain a variety of different nanosized structures, such as spherical and cylindrical micelles, vesicles, and other different types of morphologies 8,9 without using any kind of special dispersion processes.…”

The mechanical properties, thermomechanical properties, and fracture mechanic properties of block-copolymer (BCP), core-shell rubber (CSR) particles, and their hybrids in bulk epoxy/anhydride system were investigated at 23 C. The results show that fracture toughness was increased by more than 268% for 10 wt % BCP, 200% for 12 wt % of CSR particles, and 100% for hybrid systems containing 3 wt % of each, BCP and CSR. The volume content of nanoparticles influences the final morphology and thus influences the tensile properties and fracture toughness of the modified systems. The toughening mechanisms induced by the BCP and CSR particles were identified as (1) localized plastic shear-band yielding around the particles and (2) cavitation of the particles followed by plastic void growth in the epoxy polymer. These mechanisms were modeled using the Hsieh et al. approach and the values of G Ic of the different modified systems were calculated. Excellent agreement was found between the predicted and the experimentally measured fracture energies.

“…The nanocomposites thin film can also be manufactured using electrospinning [194][195][196][197] and electrospun [198][199][200] processes. These methods have gained popularity and are found to be an effective technique to also produce the electrospinning/electrospun nano-interlayers [201][202][203][204][205] which toughen the composite laminate. Klein et al [206] reported the ILFT of specimens (satin woven CFRPs) with carbon nanotube/epoxy films.…”

Abstract:Composite materials are prone to delamination as they are weaker in the thickness direction. Carbon nanotubes (CNTs) are introduced as a multiscale reinforcement into the fiber reinforced polymer composites to suppress the delamination phenomenon. This review paper presents the detailed progress made by the scientific and research community to-date in improving the Mode I and Mode II interlaminar fracture toughness (ILFT) by various methodologies including the effect of multiscale reinforcement. Methods of measuring the Mode I and Mode II fracture toughness of the composites along with the solutions to improve them are presented. The use of different methodologies and approaches along with their performance in enhancing the fracture toughness of the composites is summarized. The current state of polymer-fiber-nanotube composites and their future perspective are also deliberated.
