“…This can be explained by higher load transferring capability due to the higher interaction between NC particles and epoxy matrix. In the literature, Oner et al [ 46 ] studying the NC effects on mechanical performances of carbon/glass hybrid laminates declared that the appropriate dispersion of NC particles resulted in improved interactions between nanofillers. Further addition of NC particles resulted with the decreases, and also, 3 wt% NC filled samples (350 N) showed lower values than pure ones.…”

This study investigates the effects of nanoclay (NC) particles on the buckling behavior of carbon/Kevlar intraply hybrid composites. The laminates containing various amounts of NC particles (0.5%, 1%, 1.5%, 2%, and 3% by weight) were manufactured using hand layup stacking followed by vacuum bag molding process. The prepared samples were subjected to axial and lateral compressive loads under fixed-fixed and fixed-free boundary conditions, respectively, and the relevant critical buckling loads were determined. Furthermore, the failure modes were examined via microscopic views taken from the damaged areas on the samples to fully understand the influences of NC particles on buckling characteristics. The findings demonstrated that the buckling behaviors of the samples were significantly affected by the introduction of NC particles. Compared with the composite samples without any NC particles, the composite samples with 1 wt% NC particles showed an increase of 21.12% and 25.33% in the axial and lateral critical buckling loads, respectively. However, the inclusion of NC particles with an amount that higher than 1 wt% showed a decreasing trend in terms of critical loads for both buckling loadings, which can be viewed as a measure of load-bearing capability. Moreover, the samples filled with 3 wt% NC particles exhibited a decrement on critical loads compared with those of samples without any NC particle filler. With the help of microscopic views, the failure modes were detected as matrix fragmentation and delamination for both buckling loadings.

“…However, degradation of properties was observed while increasing the weight content of nanoplatelets beyond the critical level. Similarly, the mechanical properties of nanoclay reinforced carbon/glass hybrid composites were evaluated by Oner et al [19]. The outcomes disclosed that the addition of nanoclay enhanced the mechanical properties of the hybrid composites due to improved interactions between the reinforcements and matrix.…”

In this work the effect of stacking sequence of Carbon (C)/Glass (G) fibers and halloysites addition (1, 3 and 5 wt.%) on the mechanical and thermal properties of the hybrid composites were explored. The composite laminates were prepared by using Vacuum Assisted Resin Infusion Technique (VARIT). The outcomes disclosed that the hybrid composites having sequence of C2G3C2 (2-Carbon/3-Glass/2-Carbon layers) showed better overall properties. Moreover, the addition of halloysites enhanced the mechanical and thermal properties of the C2G3C2 hybrid composites. In particular, the hybrid composites added with 3 wt.% of halloysites showed higher overall properties among the other hybrid composites investigated. Finally, the morphological analysis was performed on the fractured surface of mechanical tested composites to study the failure mechanisms occurred. Based on the obtained results it can be concluded that the C2G3C2 hybrid composites added with 3 wt.% of halloysite could be a suitable alternative light weight material for automobile, aerospace and building structures.

In this study, the effects of various weight percentages of montmorillonite nanoclay particulates (0%, 1%, 3%, 5%, 7%, and 9%) are fabricated using the hand‐layup technique, and their physical properties are thoroughly examined. To accurately extract the specific qualities of the matrix materials, the concept of interpenetrating polymer networks (IPNs) is implemented by blending 70% epoxy and 30% polyurethane, thereby achieving meticulous control over the individual matrix properties. Besides, E‐glass fiber (biaxial woven mat) is selected as the reinforcement to provide structural rigidity to the IPN laminate. As well, to comprehensively evaluate the mechanical properties of the nanoclay and E‐glass fiber‐reinforced composites, a series of tests are conducted according to ASTM standards. These tests included dynamic mechanical analysis (with a tan δ value of 0.171), tensile strength (345.71 MPa), flexural strength (312.67 MPa), impact strength (22 kJ/m2), heat deflection analysis (HDT at 88°C), and free vibration analysis (with natural frequencies of Mode I—25.12 Hz, Mode II—158.36 Hz, Mode III—424.87 Hz, and Mode IV—736.72 Hz). Out the study, reveals that, incorporating 5% nanoclay significantly enhanced all measured properties to their maximum extent. Additionally, to gain a better understanding of the micromechanics between the fiber, particulates, and matrix, the fractured specimens are thoroughly analyzed using scanning electron microscopy. Also, study aims to employ nanoclay‐incorporated composite materials in various advanced applications such as packaging delivery systems, military systems, magnetic shielding operations, detectors, and information technology industries.Highlights Utilization of nanoclay significantly enhances the strength of composites. IPN laminates were fabricated with filler loads ranging from 0% to 7%. Mechanical properties of IPN laminates have been comprehensively investigated. DMA and vibration tests conducted to assess the aptness of the filler inclusion. SEM analyses clearly revealed superior compactness with 5% nanoclay addition.
