“…The contact friction was considered the general contact and was set to 0.3. 56 This general contact algorithm is caused to contact constraints using a penalty contact method. 57 To reach experimental test results, the contact between face sheets and the rigid sheets was assumed to be frictionless contact.…”

The present paper tries to introduce the effect of foam-filled on a type of trapezoidal corrugated core and their structures derived from the related previous studies. The main purpose of this work is to present a novel geometry of trapezoidal cores, and their configurations are inspired by the earlier works. These absorbers have been proposed to raise the specific energy absorption (SEA) while declining the initial peak crushing force. Therefore, five corrugated core sandwich panels have been tested under quasi-static axial compressive load experimentally and then simulated by ABAQUS software. The accuracy of the numerical simulations is validated by comparing the numerical results with the corresponding experimental data. Besides, some other simulations have been carried out to investigate the effect of foam density, core type, and thickness in more detail. The comparison results show that the SEA rate of bi-core sandwich panels which has not been filled by foam is better than the single trapezoidal core sandwich panels, and this rate is roughly around 70%. The best performance is relevant to the pure foam core without any trapezoidal core structure and the next item is the single foam-filled corrugated core and the lowest performance among them is related to the bi-core corrugated core foam-filled.

“…The impact behaviour of the sandwich panels is generally opposite to the one observed during the static bending tests. Skin-core delamination [26,27] and/or fibre pull-out [28] are considered to be between the main energy absorption mechanisms acting under dynamic loads. The treated SiRALs provide not only a premature delamination, but also larger deflections, including in the composite core.…”

Fibre metal laminates (FMLs) are lightweight structures with high structural performance and are suitable for many industrial applications. This work describes the impact behaviour of novel sisal fibre-reinforced aluminium laminates (SiRAL) and their dependence upon the orientations of the fibres, the composite core used and the surface treatment of the metal skins. A cold-pressing technique is used to produce SiRALs in six configurations. The FMLs here also have treated or untreated aluminium skins (2024 T3) and three different types of core materials (0°/90° fabric, ±45° fabric and random matt). The ±45° core treated SiRAL provides the highest energy absorption and deflection properties. The pre-treatment of aluminium skins using sandpaper, deep cleaning and primer significantly affects the delamination of the panels under bending impact. The findings reveal that the SiRAL concept is a promising multifunctional FML suitable for different applications that require lightweight, bending and impact performance, together with sustainability characteristics.

“…36 Even with other synthetic fibers such as glass fiber, 37,38 carbon fiber, 39 and CNT, 40 graphene, armide, structural applications, 41 automobile interior parts, medical industry, 42 musical instruments parts, and in textile industries, bamboo is becoming helpful in terms of environment aspects. 33,[43][44][45][46][47][48][49] Wang et al used zinc and ultrafine bamboo char (UFBC) to make a zinc-rich coating to protect steel from corrosion. The addition of UFBC in the epoxy coating increased the hydrophobicity of the film.…”

In the pursuit of sustainable and high‐performance materials, this study presents a groundbreaking approach to enhance the mechanical properties of glass fiber‐reinforced polymer composites. Railway waste provides an unexpected source of recycled glass fibers (RGFs), which, when combined with bamboo fibers (BFs) and nano SiO2 in a resilient epoxy matrix, unleashes a transformative synergy. The epoxy‐SiO2 matrix ratio was kept constant, that is,70% by weight while varying the ratio of RGF and BFs weight. The experimental results demonstrated notable improvements in mechanical properties. Specifically, a 36.92% increase in tensile strength was observed with an RGF and BF ratio of 20:10. Flexural strength exhibited a substantial enhancement of 44.67%, and impact strength increased by 31.28% at a ratio of 15:15. The composite achieved a remarkable 42.64% improvement in hardness, while attaining the lowest density value of 0.862 at a ratio of 25:05.Water absorption tests, conducted in both distilled and saline water, provided insights into the material's resistance to environmental conditions. The morphological and dispersion behaviors of the prepared composites were analyzed using advanced characterization techniques, including field‐emission scanning electron microscopy (FE‐SEM) to study the orientation, shape, and size of fibers and particles, bonding between the fibers and matrix, defects, voids, etc. Combined with energy dispersive x‐ray spectroscopy (EDX), FESEM allows for elemental analysis, helping to identify and quantify the chemical composition of different phases within the polymer composite. X‐ray diffraction (XRD) analysis to know the compositions of developed composites. The findings from this study underscore the efficacy of incorporating recycled materials.Highlights Extraction and reusing GF to develop a new hybrid composite. BF and RGF in epoxy‐SiO2 matrix present high mechanical property composite. Density and water absorption tests were done to see the swelling properties. Characterization technique employed to see the interphase of composites developed.
