“…The effect of montmorillonite (MMT) clay particles (1% and 3% nanoclay doping ratios) on the incubation period in solid particle erosion of glass fibers fabric/epoxy nanocomposites was presented in work [58]. The unmodified glass fiber/epoxy composite showed the highest erosion resistance in comparison to the modified composites.…”

Fiber-reinforced epoxy composites are used in various branches of industry because of their favorable strength and thermal properties, resistance to chemical and atmospheric conditions, as well as low specific gravity. This review discusses the mechanical and thermomechanical properties of hybrid epoxy composites that were reinforced with glass, carbon, and basalt fabric modified with powder filler. The modification of the epoxy matrix mainly leads to an improvement in its adhesion to the layers of reinforcing fibers in the form of laminate fabrics. Some commonly used epoxy matrix modifiers in powder form include carbon nanotubes, graphene, nanoclay, silica, and natural fillers. Fiber fabric reinforcement can be unidirectional, multidirectional, biaxial, or have plain, twill, and satin weave, etc. Commonly used methods of laminating epoxy composites are hand lay-up process, resin transfer molding, vacuum-assisted resin transfer molding, and hot or cold pressing. The following review is a valuable source of information on multiscale epoxy composites due to the multitude of technological and material solutions.

“…This expected result is primarily based on the enhanced rigidity of the composite structures with the NCs addition into the epoxy matrix, as presented in our previous studies. [ 41 ] Similarly, Rafiq et al stated that the impact load was increased up to 23% at 10 J impact energy with the nano clay additive. [ 45 ]…”

“…were detailed in prior studies. [22,41] According to previous studies' defined optimal particle ratio, the concentration of NCs in the epoxy matrix was fixed as 2.0 wt%.

“…Based on the findings presented in our prior work, it is clear that NCs reinforcement improves the bearing performance of BCJs. [41,42] However, the applied impact on the bolted joints drastically diminishes the maximum bearing load and displacements. Specifically, the maximum bearing load declines about 11% and 9% for the BCJs and BmCJs after the impact at the 3 J energy level, respectively (Figure 5B).…”

Although bolted composite joints are mainly designed to resist bearing loading, dynamic loading such as low‐velocity impact can also be a severe threat because of its potential to reduce joint reliability. Surprisingly, it is still unclear how bolted composite joints perform after the dynamic loading, and its effect on the damage tolerance is unknown likewise. This study aims to evaluate experimentally the bearing‐after‐impact (BAI) damage tolerance of bolted glass‐fiber (GF) reinforced epoxy composite joints. For this, the GF/epoxy composite laminates were assembled in single‐lap shear joints firstly, and the bolted composite joints were subjected to low‐velocity impact tests at various energy levels from 3 to 10 J. Following that, standardized bearing tests were carried out to determine the damage tolerance of the laminated composites following the impact. Nanoclay fillers were also added to the epoxy matrix to improve damage tolerance. After the low‐velocity impact loading, the bearing strength diminishes by almost 22% for the bolted composite joints, while the reduction in damage tolerance is effectively limited with the nanoclay addition. However, as the impact energy increases, the efficiency of the nanofiller declines. Increased impact energy results in changes in failure modes, and nanofillers improve damage tolerance with additional nano‐scale toughness‐increasing mechanisms.

“…The nanoclay addition to the composite has declined the mass loss. Nanoclay enhances the load-carrying ability and stiffness of the matrix, resulting in lower mass loss (Bagci et al, 2020;Rashmi et al, 2011;Shettaret al, 2020). Figure 5 presents the 2-way interaction effects plots.…”

The current study's objective is to investigate the impact of nanoclay on the tensile and wear properties of glass fiber-epoxy-nanoclay ternary nanocomposite. Three types of composites are produced by hand lay-up process and compression molding. Tensile and wear tests are executed according to ASTM standards. The findings disclosed that nanoclay enhanced the tensile properties of glass fiber-epoxy-nanoclay ternary nanocomposite. The causes for the failure under tensile load are revealed by SEM micrographs. Response surface methodology (RSM) is applied to analyse the wear loss of nanocomposite. The "Box-Behnken method" is employed for experimental design to establish the main and interaction effects among factors comprising nanoclay (NC), load, and sliding distance in three levels (0, 2, and 4 wt.% for nanoclay; 1, 3, and 5 kg for load; and 300, 600, and 900 rpm for sliding distance). The RSM offers a strong confidence model for each response. Also, RSM models are often used to estimate the optimum case with the minimum mass loss. The optimum results are estimated for the combination of 4 wt.% nanoclay, 1 kg load, and 300 rpm for sliding distance. Experimental test results revealed an agreement with the predicted values.
