“…However, as shown in the stress-strain curves (Figure 4), even though some glass fibers failed, kenaf fibers could carry the applied load until the second maximum stress was achieved. Ashraf et al (2021) also reported a similar stress-strain curve for a flax/glass hybrid composite that demonstrated elastic-brittle and dual fracture site behavior.…”

A substantial amount of kenaf fiber research has been carried out recently to incorporate more sustainable materials into the production process. For many years, scientists have studied the properties of kenaf and the hybrid composites it may form. Composites made from kenaf and synthetic fibers were the focus of the majority of the study. Similarly, the researchers discovered mechanical characteristics as a fundamental truth. Despite this, earlier research on particular properties has not permitted using kenaf composites for load-bearing purposes. Nevertheless, kenaf composites can significantly influence car exteriors and other vital applications, even if their impact characteristics are only studied in other materials science disciplines. Due to this, dynamic failure behavior and mechanism of unidirectional kenaf and kenaf/glass hybrid composite compressive response were examined. Therefore, both composite specimens were loaded compressively under static and dynamic loading at a strain rate range of 0.1/s to 1700/s. The results showed that the failure behavior and mechanism of kenaf and kenaf/glass hybrid composite were different under static and dynamic loadings. Shear banding failure occurred at 60 degrees for kenaf composites. In contrast, kenaf/glass composites were fractured longitudinally along the fiber direction under static loading. Glass fibers in hybrid composites were more vulnerable to damage under microscopic analysis because they carried most loads. Consequently, the kenaf fibers in hybrid composites were less damaged than those in kenaf composites, which had fiber breakage, fiber splitting, and fiber-matrix debonding.

“…12 Combining natural and synthetic materials can reduce cost and environmental impact. 13 The flax/glass hybrid composite performed similarly to glass fiber composites, with the benefit of low weight and biodegradable flax fiber as far as low-velocity impact behavior is concerned. 14 The study showed that hybrid composites like nonhybrid glass, kenaf, and glass/kenaf hybrid composites had better perforation and penetration resistance at all energy levels tested than the nonhybrid kenaf composite when subjected to the low-velocity impact test, the hybrid composite with the outer glass fiber layer absorbed more energy.…”

Composite structures with a pure glass composite facesheet and an aluminum honeycomb core are widely used in aircraft interiors. Because impact‐related problems are related to structural integrity and safety performance, the behavior of these structures under impact loading is critical. Due to their promising performance, lower cost, and low environmental impact, hybrid composites have recently become one of the most widely researched composite materials in the research field. This paper aims to investigate the impact behavior of nonhybrid glass and the glass partially replaced with a flax and kenaf hybrid composite facesheet caused by a low‐velocity impact. The specimens were impacted with different impacted energies, such as 10, 20, and 30 J. All nonimpacted and impacted samples were tested and compared for postimpact flexural (three‐point bending) behavior to analyze the residual strength of sandwich structures after impact. The results revealed that the hybrid composite face sheet outperformed the glass composite sandwich structure. The hybrid composite face sheet allowed the impactor to penetrate deeper, resulting in better energy absorption than the glass composite. Compared to nonimpacted specimens, the glass and hybrid face sheet combinations demonstrated comparable residual bending performance.Highlights Experimental analysis shows the impact resistance (low‐velocity impact test) and residual load‐carrying capacity (three‐point bending test) of glass and hybrid composite face sheets. Hybrid face sheets show excellent energy‐absorbing capability compared to glass one. The residual flexural strength of the glass and hybrid composites was comparable to that of nonimpacted samples. The peel strength achieved in this study using the pre‐cure fabrication process was significantly higher than the peel strength achieved using prepreg face sheets. Reinforcing the composite face sheet of the sandwich structure by partially replacing the glass with flax and kenaf fiber exhibited comparable performance.

“…Furthermore, numerous experimental works have been conducted to study the effect of hybridization on tensile strength, impact strength and the effective properties of the composite. [13][14][15] The FEM has great success in solving various problems in many fields, but it also has limitations, especially in the computational time. This limitation often motivates researchers to move to other methods such as Meshless, Proper Generalized Decomposition (PGD), Boundary Element Method (BEM), and others, which proved their ability to solve some FEM limitations.…”

In the present study, the stress distribution and first ply failure strength of hybrid laminated composites subjected to uniaxial tensile and compression loads are predicted using Isogeometric analysis (IGA) based on non-uniform rational B-splines technology, commonly referred to as non-uniform rational B-splines (NURBS) technology. The obtained results were compared to finite element method results (ANSYS) published in the literature and analytical results using Autodesk Helius Composite software. Graphite-glass/epoxy hybrid composite plates are analyzed for different lamination orientations and used to calculate first ply failure strength. Non-interactive theories such as maximum stress, maximum strain, and fully interactive criteria such as Tsai-Wu, Tsai-Hill and Hoffman are used to predict the failure strength of different laminates. The failure envelopes of the hybrid composites are developed using the same failure criteria used for the graphite-glass/epoxy hybrid composite. The effects of IGA refinement and plate’s dimension on the present analysis were also established. The IGA results showed good accuracy, robustness and good convergence speed with the analytical software results and the finite element method (FEM) reference value.
