Epoxy resins (EPs) exhibit various extraordinary properties, including significant mechanical and thermal properties, low shrinkage, and high chemical resistance, opening a wide window of different applications such as adhesives, paints, coatings, etc. By contrast, EPs also have the undesirable behavior of being brittle and cannot sufficiently resist against the initiation and growth of cracks. Efforts are being made to enhance the toughening of EPs without sacrificing their other desirable properties. With the advent of nanotechnology, improving the toughening of EPs has gained momentum by incorporating different modified and unmodified nanofillers into these polymers. Since the discovery of carbonaceous nanofillers, especially carbon nanotubes (CNTs) and graphene (Gr), significant progress has been made in the development of EP‐based composites incorporating these nanofillers and their hybrids. The current review presents research progress during the last six years on the toughening of EPs using CNTs, Gr, and CNT‐Gr hybrids. Special attention is given to the chemical functionalization of these nanofillers, which has been demonstrated over and over again to significantly affect nanofiller dispersion in the EP matrix and subsequently its fracture properties. Details on the various toughening mechanisms of EP‐based composites are further provided.

Sandwich composite structures are widely used in various industries namely, aerospace, automotive, packaging, biomedical, civil and electronics due to their high specific strength and energy absorption capabilities. Mechanical properties of sandwich structure depend on material properties of face sheet and core, and strength of face sheet-core interface. Most commonly used composite materials are carbon fiber reinforced plastics, glass fiber reinforced plastics, ceramic matrix composites, and metal matrix composites. Several researchers have used nano-fillers namely, nano-clay, carbon nanotube, and nano-silica for improvement of mechanical properties of composite structures.In this paper, an extensive literature review has been discussed regarding influence of various material and geometrical parameters on mechanical properties of sandwich composite structure. Initially, influence of various fiber reinforcement and nano-fillers on mechanical properties are discussed. Then, deformation behavior and mechanical properties of honeycomb core is elaborated.Further, influence of temperature variation on composite structure is discussed. Moreover, crucial insights on reviewed literature are presented and future advancements in the field of sandwich composite structure are discussed.

“…It is observed from previous studies that by adding the nano-fillers into the matrix material of the composites, a great enhancement in the mechanical properties of the material can be achieved. [3][4][5][6][7][8][9][10] The review articles 3,11 suggest that GNPs can be a great alternative to Carbon Nano Tubes (CNTs) in terms of performance and cost. Graphene nanoplatelets have emerged as a promising reinforcement for glass fiber-reinforced composites due to their exceptional mechanical, electrical, and thermal properties.…”

Detecting the low-velocity impact damage on the FRP composite structures can be challenging because the visible signs on the surface may be subtle. Mitigating the effects of BVID (Barely Visible Impact Damage) is crucial in ensuring the safety and reliability of composite components, especially in industries where these materials are commonly used, such as aerospace and automotive. This article explores the experimental investigations of the impact and post-impact damage propagation under compression in the Graphene Nano-Platelets (GNPs) infused glass fiber epoxy composite laminates. A comparative study of varying the percentage of the nano-platelets (0, 0.25, 0.5, and 0.75%) in the matrix material of the composite laminate is presented. The impact tests at low energies (15 J, 20 J, and 25 J), followed by the quasi-static compression tests, are carried out as per the procedures mentioned in the ASTM D7136/D7137. The digital image correlation technique (DIC) is used to measure strains and plot the strain field on the impacted face of the specimen under compression. Damage envelopes of the impact and compression tests are studied using X-ray CT scans. Micro-level failures are observed through Scanning Electron Microscopy (SEM) to get better insights into the failure mechanism of the composite materials under impact and compression loadings. Upon completing the study, it is found that the addition of the GNP into the matrix materials not only increased the impact performance but also increased the load-carrying capacity of the laminate under compressive loading. A decrement of 2–21% in the energy absorbed in the damage formation is seen with the incorporation of GNPs into composite materials. A maximum increment of 17% in the compressive strength is observed for the composite laminates with the 0.75% GNPs. However, for a particular percentage of the GNP, the compressive strength of the laminate is reduced with an increase in impact energy compared with its virgin counterpart. From X-ray CT scans, it is seen that the laminate under the compression tests fails due to excessive ply-splitting and the delamination at the damage site created during the impact. Fiber breakage, fiber brooming, matrix cracking, fiber-matrix debonding, etc., are some of the other failure modes observed in SEM studies.
