“…Wang et al [ 157 ] studied the influence of GNPs, CNTs, and their hybridization on Mode I inter‐laminar fracture toughness of EP/CF composites. They compared different GNPs sizes and contents to prevent their aggregation in EP, which could significantly decrease the mechanical properties of the final composite.…”

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.

This paper explores the effects of woven fabric structures on the biaxial tensile mechanical properties and burst properties of woven fabric for layflat hose. A repeat unit cell finite element modeling for woven fabrics for layfalt hose is adopted. To investigate the effects of fabric structure, two parameters are studied: warp yarn spacing and weft yarn linear density. The mechanical response outcomes such as stress distribution, intensity, breaking elongation, and burst properties such as burst pressure, burst direction, are defined and the effects of structure parameters studied on these outcomes are studied. The effects of the warp yarn spacing and the weft yarn linear density on the biaxial tensile mechanical properties and the burst properties of woven fabric for layflat hose are determined. Moreover, the results suggest finite element method exhibits high accuracy in predicting the burst pressure of layflat hose.

“…[30] Other authors have reported that seawater aging in general affects the flexural and impact properties of GFRP composites with MWCNTs [23,24] and the creep lifetime of graphene oxide embedded GFRPs. [31] It has been recently shown that the effective mixture of CNS (CNTs and GNPs) results in hybrid CNS with three-dimensional structures, which provides a synergistic effect on the physical and mechanical properties of polymer nanocomposites, [32][33][34][35] GFRPs, [36,37] carbon fiber reinforced polymers, [38][39][40][41][42] and fiber metal laminates. [43] However, there is no research work that reports the incorporation of hybrid combinations of CNTs and GNPs to the GFRP laminates by spray coating technique and evaluates its effect on the mechanical and thermomechanical properties under a hydrothermal environment like seawater aging.…”

The influence of seawater aging on the flexural and thermomechanical properties of glass fiber/epoxy (GF/E) composites containing the hybrid combination of multiwall carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) was experimentally investigated in this work. The three-point bending and dynamic mechanical analysis were performed to test flexural modulus, flexural strength, strain to failure, storage modulus, and glass transition temperature (T g ) of hybrid MWCNT/GNP-GF/E composites at different mixing ratios (1:0, 7:1, 3:1, and 0:1) which were immersed in seawater at 60 C. The results confirm that seawater aging plays a significant role in reducing the mechanical and thermomechanical properties of hierarchical composite laminates due to degradation and weakening of the fiber/matrix interface as a consequence of plasticization and swelling effects of the polymer matrix. Despite this serious physical degradation, MWCNT/GNP-GF/E hybrid composites with (7:1) showed a better resistance to seawater aging, with slight improvements in flexural strength (2%), strain to failure (14%), and T g (12%) compared to neat GF/E composites, due to positive synergistic effect of the carbon nanostructures in the composite laminates, making them suitable for marine applications.
