“…[26] Fig. (7) Stress-strain curve of the composites Figure 8 shows the effect of the composite density on the ultimate tensile strength as the one of the improvements proven figure 5, the laminate configuration in COMP 3 as the fiberglass is the core laminate shows the better specific ultimate tensile strength due to the better tensile load withstanding and distribution of woven fiberglass [27]. The amount of strain energy stored per unit volume of the material up to fracture divided by the density of composite which defined the specific modulus of toughness [28], figure 9 expresses the variation of this property in the different investigated where there findings agrees with the strain results in figure 10, Even though the hybrid reinforced COMP 3 has an absolute advantage over the polyester fiber composite when the weight is essential factor as a result of the addition of tire rubber particles.…”

“…The performance of sandwich structure mainly depends on the skins, the core, and the skin/core interface (film adhesive) as well as their constituent materials and geometrical dimensions [2]. The skins carry the tension and compression flexural loads and the cores carry the shear loads [3]. Increasing the core's thickness induces a higher stiffness with a little weight gain, and this has urged the researchers to further investigate the sandwich strength/stiffness using different skin materials (e.g., aluminum, carbon, composites, aramid and glass) and various core materials (e.g., metallic: aluminum or steel and nonmetallic: honeycomb glass, aramid or carbon fabric; balsa wood, cell foams, and syntactic) [4,5].…”

The developed design of sandwich structure and the appropriate selection of its core materials and geometries proven its efficient applications in lightweight structures. This study aims to quantify the best core geometries and positions that can carry a higher stiffness without weight compromising. To do so, the flexural strength applying fourpoint bending test, compressive strength and stiffness of aluminum (Al) facesheets strengthened by two different aluminum corrugated square and triangle cores, oriented in flatwise and edgewise positions, i.e., flatwise square (FS), edgewise square (ES), flatwise triangle (FT), and edgewise triangle (ET). The results indicated the sandwich panels with ET core had the highest flexural strength of 28 MPa at lower deflections, and the lowest strength of 13 MPa for panels with FT cores. The highest compressive strength of 81 MPa and the highest specific strength of 516 MPa/Kg were obtained with ES core sandwich panels co MPa red to 21 MPa and 120 MPa/Kg for panels with FT core. For all cases, the deformation occurred near surface buckling and core crushing. The sandwich panels with ET and ES cores showing a higher load-carrying capacity under the bending load due to the standing direction of the stiff Al struts, while the sandwich structures with FT and FS cores have totally slipped, bent and destroyed at lower loads. This study provides advice for the development of sandwich structures with various core geometries/orientations used in a range of engineering applications.

The rapid advancement of polymer composites, particularly those reinforced with hybrid kenaf, has positioned them as viable structural materials across diverse industries such as automotive, defense, aerospace, marine, construction, and naval. Despite their growing popularity, recent advances in kenaf yarn‐reinforced thermoplastic acrylonitrile butadiene styrene (ABS) composites for structural applications need more comprehensive coverage in the literature. This article addresses this gap by critically examining the influence of quasi‐isotropic stacking orientation on water absorption, flexural strength, and impact properties in kenaf yarn fiber‐reinforced ABS composites. Prepared using hand layup and compression molding techniques, the composites featured varying stacking orientations, including 0°/0°/0°/0°, 0°/90°/0°/90°, −45°/90°/0°/45°, 90°/−45°/0°/45°, 90°/0°/45°/−45°, and 0°/45°/−45°/90° for kenaf yarn reinforced ABS. The findings reveal that the 0°/45°/−45°/90° configuration offers the best overall mechanical properties and water penetration resistance among quasi‐isotropic stacking sequences, exhibiting low water uptake and higher tensile and flexural strengths of 35.3 and 85.4 MPa, respectively, compared to other sequences. This suggests that incorporating ±45° plies contributes to a balanced distribution of mechanical strength and modulus across different directions, making the 0°/45°/−45°/90° configuration ideal for high‐strength structural applications in kenaf yarn/ABS composites.Highlights Fiber stacking orientation is the key factor affecting the mechanical performance of kenaf‐based composites. Using the hand layup technique, six stacking orientations (0°/0°/0°/0°, 0°/90°/0°/90°, −45°/90°/0°/45°, 90°/−45°/0°/45°, 90°/0°/45°/−45°, and 0°/45°/−45°/90°) were employed to create kenaf fiber‐reinforced ABS composites. A quasi‐isotropic sequence of 0°/45°/−45°/90° allows the least water penetration due to the strategic placement of ±45° plies in the middle layers of composites. 0°/45°/−45°/90° configuration offers the best flexural and tensile properties due to better force distribution within the ±45° plies in the middle layers. Under surface morphological analysis, the optimal fiber stacking sequence contributes to fewer voids and fiber pull‐outs.
