“…[2][3][4] One of the most sensitive materials to the growing micro-cracks can be thermoset composites like epoxy-based composites. 5,6 For this reason, creating the healing behaviors in these composites can reduce the hazards of catastrophic failure in these materials under mechanical conditions, especially in fatigue loadings. 7,8 The creation of healing ability in conventional composites like glass fibers/epoxy or carbon fibers/epoxy composites can be performed by intrinsic or extrinsic methods.…”

In the current study, the effect of adding the encapsulated healing agent with neat polymeric and nanocomposite shells on the mechanical‐healing features of glass fibers/epoxy composite under various loads was investigated. Therefore, the microcapsules with urea‐formaldehyde (UF) nanocomposite shell containing the various weight fraction of silica nanoparticles (0, 1, 2, 3) were synthesized. After that, the flexural, tensile, and interlaminar shear strength (ILSS) samples were destructed by using the quasi‐static penetration method with the damaging force of 500, 1050, and 2900 N, respectively. The maximum healing efficiency in the flexural loads belonged to the composite with the 3 wt% nanosilica on the surface of microcapsules, which was 83.9%. Also, it was found the increment in the weight fraction of silica nanoparticles had a negligible effect on the healing ability of composite under tensile loading. Achieving 135.8% healing efficiency in the composite with the 2 wt% nanosilica under the shear loads can be one of the most important findings in this work.

“…In recent years, nano‐scale reinforcements have become essential to enhance the fiber–matrix interface. [ 15 ] The reinforcements such as carbon nanotube (CNT), [ 16,17 ] SiO 2 , [ 18 ] nanoclay, [ 19,20 ] graphene, [ 21–23 ] CaCO 3 , [ 24 ] and Al 2 O 3 [ 25 ] represented enhancements on the mechanical, thermal and chemical properties of composite materials. On the other hand, halloysite nanotubes (HNTs) are abundant nano particles with tubular 1D structure, large aspect ratio, natural existence, prosperous functionality, good biocompatibility, and high mechanical properties.…”

One of the biggest obstacles to fiber-reinforced composite laminates is out-ofplane dynamic loading. Specifically, low-velocity impact loading in an out-ofplane direction leads to matrix cracking, delamination, and fiber breakage damages due to weak fiber-matrix interactions. This paper aims to examine the dynamic loading behavior of nano reinforced glass/epoxy composite laminates under various impact energies. Moreover, to enhance fiber-matrix interaction, halloysite nanotubes (HNTs) with lower cost among the nanotube morphologies such as carbon and TiO 2 were introduced to the epoxy matrix.The impact performance and the damage propagation were also investigated. As a result, the HNT-reinforced multiscale composite sample had 28% more impact load carrying capacity and absorbed 18% less energy than its unmodified counterpart. Image processing was utilized to determine the damage evaluation by analyzing both front and back surfaces. The improvement of the fiber-matrix interface with HNTs reinforcement resulted 59% and 46% less damage to the front and back damage surfaces, respectively. The acquired results were supported by macro-size examination and micro-size analyzing via scanning electron microscopy (SEM). These results pave the way towards designing fiber reinforced composites to be utilized for the transportation of dangerous liquids such as acids or solvents.

“…Epoxy (EP) resins are now widely utilized as structural materials owing to their outstanding properties such as low curing shrinkage, high chemical resistance, good corrosion resistance, high mechanical strength, and appropriate thermal stability 1–3 . In recent years, several works have been done to reinforce the EP resins through the incorporation of nanofillers like nanoclay, 4 carbon nanotubes, 5,6 carbon nanofibers, 7 graphene nanoplatelets, 8,9 CaCO 3 , 10 Al 2 O 3 , 11 SiO 2 , 12 ZrO 2 , 13 TiO 2 , 14 and so forth. Among them, graphene has attracted considerable attention due to their outstanding mechanical, electrical, and thermal properties.…”

In this work, a chemical precipitation procedure for decorating graphene oxide (GO) with Fe2O3 nanoparticles was described. Iron(III) chloride (FeCl3) was employed to generate the nano‐Fe2O3 particles onto the GO surface in the presence of sodium hydroxide. The Fe2O3@GO hybrid was characterized by various techniques of X‐ray diffraction, Fourier transform infrared spectroscopy, Field‐emission scanning electron microscope, Raman spectra, and Atomic‐force microscopy. The epoxy (EP)‐matrix nanocomposites containing various Fe2O3@GO loadings (0–0.8 wt% at a step of 0.2) were prepared by mechanical stirring and ultrasonic treatment. Mechanical properties of these composites were explored using the three‐point bending and dry‐sliding wear tests. The results revealed that the best flexural and wear behaviors were related to the specimens containing 0.2 and 0.6 wt% Fe2O3@GO hybrid, respectively. The incorporation of 0.2 wt% Fe2O3@GO was found to increase the flexural strength and modulus by 24% and 29%, respectively. Additionally, mass reduction and friction coefficient were decreased by 97% and 66% respectively, due to the addition of 0.6 wt% Fe2O3@GO. Most importantly, in comparison with the untreated‐GO/EP composite, the specimens containing Fe2O3@GO have attained higher improvements in flexural and wear properties. Finally, morphology of the fractured and worn surfaces was also evaluated.
