Research on interfacial toughness of laser‐induced graphene and short Kevlar fibers aramid fiber/foam aluminum sandwich structure

AbstractThe interface performance of the aramid fiber/foam aluminum sandwich structure is poor due to the lack of fiber connections between the core and face sheets, negatively impacting overall load‐bearing capacity. This study investigates the effects of laser‐induced graphene (LIG) and short Kevlar fibers on the interfacial toughness of aramid fiber/foam aluminum sandwich panels, aiming to enhance the interfacial bonding capability of the structure. Results demonstrate that the synergistic toughening effect of LIG and short Kevlar fibers significantly improves the interlaminar toughness, with a 134.90% increase in peak load and a 161.64% increase in energy absorption during the three‐point bending tests. Scanning electron microscopy (SEM) analysis reveals the toughening mechanism: the micro‐porous structure of LIG provides effective adhesion points for the short Kevlar fibers, creating a stable fiber bridging structure that mitigates interface delamination. Furthermore, optimization of the surface density of the short Kevlar fibers for the LIG‐coated aramid fiber/aluminum foam sandwich panels shows a trend of increasing toughness followed by a decline with increasing surface density, with optimal interfacial performance achieved at a surface density of 6 g/m2. These findings suggest that the combined approach of LIG and short Kevlar fibers is an effective strategy for enhancing the interfacial toughness of aramid fiber/foam aluminum sandwich panels, with promising applications in composite materials.Highlights LIG‐Kevlar fibers improve toughness & energy absorption in sandwich panels. The optimal short Kevlar fiber density for interfacial performance is 6 g/m2. LIG‐Kevlar forms a “bridging structure” to prevent delamination.

Comprehensive review of modeling and material selection for hybrid sandwich composites for ballistic impact application using Six Sigma DMAIC methodology

Natural fiber-based PMC (polymer matrix composites) have recently been increasingly popular because of their reduced product weight, low material costs, and renewable sources. Hybrid composites with different combinations of fibers/matrix are attracting interest from many manufacturing industries and researchers for various applications because of their specialized mechanical and impact properties. Hybridization is one of the most essential and indispensable strategies to improve composite material performance. Hybrid sandwich composites are reviewed to enhance the mechanical properties. They mainly concentrate on improving impact properties with increased energy absorption and penetration behavior, making them competent for advanced applications. The most time-consuming and challenging task is identifying the suitable composite material for a specific application. Selecting a suitable fiber and matrix is a difficult job for impact applications because the impact can cause severe damage to composite used in structural applications. The main objective of this review is to select suitable fiber and matrix combinations for impact application by exploring the literature gap. The Six Sigma DMAIC methodology provides a different approach to the selection of material. The benefit of this methodology is the choice of material has been made based on a twofold decision-making process that provides an accurate result. In addition to this blending, the qualitative approach (Pugh method) and the quantitative approach (Analytical hierarchy process) produce more accurate results during the comparison process, making it easier to choose the best material.

Geometry Optimisation of a Wave Energy Converter

The geometry optimisation of a point-absorber wave energy converter, focusing on the increase in energy absorption derived from heave forces, was performed. The proposed procedure starts by developing an initial geometry, which is later evaluated in terms of hydrodynamics and optimised through an optimisation algorithm to tune the shape parameters that influence energy absorption, intending to obtain the optimal geometry. A deployment site on the Portuguese coast was defined to obtain information on the predominant waves to assess several sea states. NEMOH and WEC-Sim (both open-source software packages) were used to evaluate the interaction between the structure and the imposed wave conditions. The results extracted and analysed from this software included forces in the six degrees of freedom. Under extreme wave conditions, the highest increase in the relative capture width between the initial and final shapes was around 0.2, corresponding to an increase from 0.36 to 0.54, while under average wave conditions, the increase only reached a value of around 0.02, corresponding to an increase from 0.22 to 0.24, as calculated through the relative capture width values.

Alleviating interfacial thermal residual stress of carbon fiber-reinforced composites by molecular pulley effect of aldehyde-functionalized polyrotaxane

Herein, to alleviate interfacial thermal residual stress (ITRS) while improving the interfacial toughness and strength of carbon fiber reinforced polymer composites (CFRPs) the aldehyde-functionalized polyrotaxane (afPR) was synthesized and incorporated into naphthalenediimide (NDI) at the CFRP interphase. The formation of afPR was confirmed by nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR). Unsized CFs (uCF), NDI modified CFs (NCF), and the CFs (N0.5afPR-CF) modified by NDI with 0.5 weight ratio of afPR were prepared and characterized. The chemical activity and roughness of N0.5afPR-CF were increased. N0.5afPR-CF/EP exhibited a 76.14% enhancement in interfacial shear strength (IFSS), an enormous increase in energy absorption by 426.15%, a remarkable increase in interfacial toughness by 342.19%, and a significant alleviation of 73.13% in thermal residual stress (ITRS) compared to unsized CF reinforced composites (uCF/EP), due to the molecular pulley effect of afPR. The toughening and strengthening mechanism of N0.5afPR-CF/EP had also been proposed.

Numerical and experimental analysis of body armor polymer penetration resistance against 7.62mm bullet.

Advanced materials are crucial for enhancing soldier safety through improved personal body armor. In contrast to conventional Kevlar-epoxy composites, this study examines the ballistic performance of a unique ECO-UHMWPE (Ultra-High Molecular Weight Polyethylene) vest. The aim is to achieve a lightweight design with superior impact resistance, addressing limitations of the current armor used by the Ethiopian Defense Force. A comprehensive finite element analysis (FEA) was conducted using Abaqus explicit dynamics software to simulate the impact of 7.62×39 mm projectiles at various ranges (50m, 100m, 150m, and 200m). Material properties, laminate thickness, projectile velocity, and number of layers were systematically varied to assess their impact on vest performance. Results showed that ECO-UHMWPE vests exhibited significantly lower stress values and minimal deformation, particularly at close ranges with high projectile kinetic energy, outperforming Kevlar vests. Ballistic testing validated the FEA, with ECO-UHMWPE vests achieving a 22.44% weight reduction (3.49kg, 12mm thick) compared to traditional Kevlar vests (4.5kg, 15mm thick) and offering a 30% reduction in deformation and a 25% increase in energy absorption. This analysis demonstrates the potential of ECO-UHMWPE for lighter, more effective body armor, paving the way for next-generation personal protective equipment.

Drop‐Weight Impact Analysis of Unidirectional Sisal Fiber –Reinforced Epoxy Resin Composite Material for Automotive Application Based on ASTM D‐7136 Standard

The main goal of this study is to investigate the drop‐weight impact analysis of sisal fiber–reinforced epoxy resin composite materials for automotive applications using Abaqus/CAE software based on the ASTM D‐7136 standard. For this simulation, a [0/0]s unidirectional sisal/epoxy composite laminate with an overall thickness of 2.16 mm was used, and 0.5, 1, 2, and 3 kg of a rigid hemispherical impactor mass with 1, 2, and 3 m/s of velocities were used to deal with their effects on the composite laminates. The result revealed that the initial damage mechanism in the impact event is the interplay matrix crack. After that, matrix and fiber debonding, fiber breakage, and penetration occurred depending on the mass and velocity of the impactor. In addition, when the impactor mass and velocity increase, the composite plate’s reaction forces and energy absorption increase up to 1 kg of the impactor at 3 m/s. However, for 2 and 3 kg of the impactor mass, the energy absorption capacity of the material is decreased due to the high damage and perforation of the composite laminate. In general, it is found that the unidirectional sisal fiber–reinforced epoxy resin composite material has a moderate energy absorption capacity in the transverse direction and has the potential to be used for different automotive interior body applications.

Toughening of thermoset composites using glass/polypropylene commingled stitching yarns.

This paper investigates the damage resistance and tolerance of thermoset composite laminates stitched by glass and hybrid glass/polypropylene commingled yarns. Different impact energies (10-70J) were applied to stitched composite laminates before compression after impact (CAI) tests were conducted. The results showed that, except for 70J, commingled yarn-stitched laminates absorbed more energy than glass-stitched laminates. Compression tests revealed that glass-stitched and commingled composites had, respectively, 2% and 5% higher compressive strengths than unstitched laminates. After being impacted to 10-70J energies, glass yarn stitched laminates kept 83-36% of their compressive strength, while commingled yarn stitched laminates retained 73-40%, showing that the commingled yarns were more efficient at higher energies. The study found that integrating plastically deformed fibres into hybrid stitching yarns increased energy absorption and composite fracture mechanism by encouraging fibre/matrix debonding, resulting in fewer fibre breakages.

Experimental study and investigation of energy absorption and crashworthiness in thin-walled square tubes with elliptical surface defects

Abstract Today, the impact phenomenon is of particular importance. The Axial drop impact test can be used in various industries such as aviation, shipbuilding, automobile, railway, and elevators. In this research, the behavior of thin-walled energy absorbers with a square cross-section and the creation of elliptical defects on the side surfaces have been subjected to the impact test of a weight falling at a low speed. The influence of small and large oval diameters on collapse behavior and energy absorption has been investigated. It is worth mentioning that all samples are made of 1100 series aluminum. The results showed that as the large side of the rhombus increases, the initial maximum force decreases. On the other hand, energy absorption increases, which is desirable as an energy absorber, and up to 18% improvement in the absorber’s performance is created. Also, from the results of the experimental tests, it was found that with the increase of the small side of the oval from 3 to 5 mm, the initial maximum force decreases by 7%.

Development of Palm Oil-Based Polyol for the Environmentally Sustainable Production of Polyurethane Foam

This study synthesized bio-polyols from epoxidized palm oil (EPO) and polysorbate (Tween20), and developed polyurethane foams using these bio-polyols. FT-IR confirmed the formation of urethane linkages, with increased EPO ratios enhancing urethane content. SEM showed that the PU foams exhibited a spherical open-cell structure, with cell sizes increasing at higher EPO ratios. The compressive modulus decreased with higher EPO ratios at an NCO/OH molar ratio of 0.8, whereas compressive strength increased at an NCO/OH molar ratio of 1.0 due to thicker cell walls and enhanced urethane linkages. Resilience tests showed increased energy absorption with higher EPO ratios, attributed to phase mixing and the presence of free urethane and urea. These findings suggest that EPO-based polyol PU foams could be used in applications such as cushioning, noise reduction, and vibration energy mitigation, primarily in the furniture, bedding, carpet underlay, and transportation industries.

Iron Deficiency in Tomatoes Reversed by Pseudomonas Strains: A Synergistic Role of Siderophores and Plant Gene Activation.

An alkaline pH in soils reduces Fe availability, limiting Fe uptake, compromising plant growth, and showing chlorosis due to a decrease in chlorophyll content. To achieve proper Fe homeostasis, dicotyledonous plants activate a battery of strategies involving not only Fe absorption mechanisms, but also releasing phyto-siderophores and recruiting siderophore-producing bacterial strains. A screening for siderophore-producing bacterial isolates from the rhizosphere of Pinus pinea was carried out, resulting in two Pseudomonas strains, Z8.8 and Z10.4, with an outstanding in vitro potential to solubilize Fe, Mn, and Co. The delivery of each strain to 4-week-old iron-starved tomatoes reverted chlorosis, consistent with enhanced Fe contents up to 40%. Photosynthesis performance was improved, revealing different strategies. While Z8.8 increased energy absorption together with enhanced chlorophyll "a" content, followed by enhanced energy dissipation, Z10.4 lowered pigment contents, indicating a better use of absorbed energy, leading to a better survival rate. The systemic reprogramming induced by both strains reveals a lower expression of Fe uptake-related genes, suggesting that both strains have activated plant metabolism to accelerate Fe absorption faster than controls, consistent with increased Fe content in leaves (47% by Z8.8 and 42% by Z10.4), with the difference probably due to the ability of Z8.8 to produce auxins affecting root structure. In view of these results, both strains are effective candidates to develop biofertilizers.

Energy Absorption in a Rotating Rigid Honeycomb Based on Reinforced Ribbed Plates

This article proposes a rotationally reinforced ribbed honeycomb structure by incorporating struts into the rotationally rigid honeycomb to enhance its stiffness. Finite element models of the honeycomb are developed using Abaqus/Explicit and validated through quasistatic experiments for accuracy. Based on the models, a series of studies on the honeycomb's structural behavior are conducted. Initially, the mechanical properties of the honeycomb under varying loading conditions and rib angles are analyzed. The results indicate that the RSH‐45 configuration exhibits the most favorable mechanical properties under both X‐direction and Y‐direction loading conditions. Specifically, under impact in the X‐direction, the RSH‐45 and RSH‐60 configurations demonstrate increases in energy absorption of 114.64% and 96.9%, respectively, compared to the RSH‐90 configuration. Subsequently, the mechanical properties of the RSH at different impact velocities are examined. The negative Poisson's effect of the RSH is most pronounced at low‐velocity, with the deformation modes changing as velocity increases. Under medium‐velocity impacts, RSH‐45 and RSH‐60 configurations exhibit a significant negative Poisson's ratio effect, while RSH‐75 and RSH‐90 configurations display a positive effect. In summary, reinforcing ribs produces a significant negative Poisson's ratio effect only at specific angles.

Optimization of auxetic tubular structures with dragonfly-wing-shape cells through advanced multiobjective optimization techniques

Abstract Interest in auxetic structures has surged due to their unique mechanical behavior, including a negative Poisson’s ratio and exceptional energy absorption capabilities. This study aims to enhance the mechanical properties of tubular structures using a dragonfly-shaped auxetic unit cell. An optimization framework is implemented to simultaneously minimize three critical structural objectives: Poisson’s ratio, mass, and stress. Numerical simulations facilitate metamodeling via the response surface method, creating surrogate models that accurately represent each response variable. A metaheuristic optimization technique, the Non-dominated Sorting Genetic Algorithm (NSGA-II), is then employed to optimize these responses for compression performance. Experimental validation supports the numerical findings, with two optimized designs proposed. The first design (TOPSIS 1) shows reductions in Poisson’s ratio by up to 3% and stress by 45%, while the second design (TOPSIS 2) demonstrates a stress reduction of 498%. Additionally, experimental validation reveals significant improvements in energy absorption capabilities, with TOPSIS 1 and TOPSIS 2 increasing energy absorption by 58% and 545%, respectively, compared to the baseline. The integration of Industry 4.0 concepts, such as additive manufacturing and numerical simulation, proves essential in achieving efficient and effective outcomes, highlighting the importance of advanced manufacturing techniques in enhancing structural design paradigms.

Effect of Nanofillers on the Flexural Performance of 3D Fibre-Reinforced Composites

The aim of this study is to improve the flexural performance and damage mechanism of nano-filled three-dimensional orthogonal woven E-glass/epoxy composites (3DOWC). The inherent brittleness of epoxy-based 3DOWC leads to the early onset of damage mechanisms such as matrix cracking, fibre-matrix debonding, and fibre failure. To overcome these limitations, epoxy resin has been modified with nano-fillers such as graphene nanoplatelets (GNP) and the novel nanostrength® (NS). The epoxy resin was infused in 3DOWC using VARI with different weight percentages of GNP (0.5, 1.0, and 1.5 wt.%) and NS (2.5, 5.0, and 7.5 wt.%). Three samples in each warp and weft direction of 3DOWC were tested in a three-point bend test. The results showed an increase of 48.4%, 56.2%, and 27.4% in flexural strength, final failure, and energy absorption under warp-loading with 0.5 wt.% GNP, respectively, whereas weft-loaded samples with 1.5 wt.% GNP exhibited 12.0% and 10.5% increases in flexural strength and final failure, respectively. However, 7.5 wt.% NS showed an increase in flexural strength in the warp and weft directions by 36.9% and 39.3%, respectively, and an increase in final failure and energy absorption in the warp direction by 39.4% and 12.3%, respectively. For weft-loaded samples, the final failure increased by 39.3% for the same weight percentage, but there was no significant increase in energy absorption in this direction. Scanning electron microscopy (SEM) of damaged samples revealed that crack reconnection by GNP and fibrils formation and plasticization by NS particles improved the overall flexural performance of 3DOWC.

Innovative auxetic tubular reinforced metamaterial: Design and mechanical performance

In this study, we present the design, fabrication, and investigation of an innovative auxetic tubular reinforced (ATR) metamaterial. The mechanical properties and deformation characteristics of ATR metamaterials were comprehensively analyzed under quasi-static compression in both axial and radial directions. We conducted a comparative analysis between the ATR metamaterials and the original auxetic tubular (AT) metamaterials, employing both experimental and finite element methods. The findings indicate that the ATR structure surpasses the original AT structure in terms of mechanical properties during quasi-static compression in both directional orientations. Subsequently, a meticulous parametric analysis of the rotation angle of the reinforced straight ribs, a pivotal structural parameter, was conducted. The outcomes revealed that the rotation angle of the reinforced straight ribs, serving as a geometric parameter, can effectively influence the Poisson's ratio of the ATR structure. As the rotation angle of the reinforced straight rib increases, the ATR structure demonstrates superior energy absorption. The optimized ATR structure, in comparison to the original AT structure, showcases notable enhancements, exhibiting a 215 % improvement in energy absorption (EA), a 62 % increase in specific energy absorption (SEA), and a 46 % rise in energy absorption efficiency (EAE) under axial quasi-static compression. Moreover, under radial quasi-static compression, the optimized ATR structure displays a remarkable improvement, featuring a 514 % increase in EA, a 230 % rise in SEA, and a 52 % enhancement in EAE.

Dynamic splitting tensile properties of high-strength ultrahigh-toughness cementitious composites (HS-UHTCCs)

In this study, the splitting tests were conducted to examine the effect of strain rate on the splitting tensile performance of high-strength ultrahigh-toughness cementitious composites (HS-UHTCCs). Hydraulic machine and split Hopkinson pressure bar (SHPB) were used to investigate the tensile properties of HS-UHTCCs. The strain rates ranged from 10−6 to 10−3 s−1 for hydraulic machine experiments and from 5 to 15 s−1 for SHPB tests, respectively. The splitting tensile strength, tensile stress-strain curves, dynamic increase factor (DIF) and energy absorption ability of HS-UHTCCs were analyzed. The new DIF models proposed for HS-UHTCCs fit well with the experimental data. In addition, the failure modes of specimens and fibers were investigated. The splitting tensile strain was obtained from digital image correlation (DIC) tests. The results indicate that the strain rate has a significant effect on the splitting tensile strength and energy absorption ability of HS-UHTCCs. On the contrary, the average splitting tensile strain showed a decreasing trend with the increase of strain rate. Besides, the DIF model of HS-UHTCCs was proposed with experimental data. The failure modes of specimens changed at high strain rates, transitioning from remaining intact to completely splitting into half. Two failure patterns of polyethylene (PE) fibers included pull-out failure and rupture were observed, while steel fibers experienced pull-out failure.

Key effects on the structural behavior of fiber-reinforced lightweight concrete-ribbed slabs: A review

Abstract A concrete slab is one of the chief structural members in buildings, considered the most prominent member consuming concrete. Structural engineers are challenged to work on the new trend introduced using different slabs. One-way ribbed slabs are commonly used in construction due to their efficiency in spanning long distances while maintaining a low overall depth and giving the least possible number of columns. The main limitation of slab design in the construction of a reinforced concrete structure is the span between columns; a greater span between columns necessitates more supported beams or increased slab thickness; these requirements lead to an increase in the structure weight due to other concrete and steel which make the structure more costly. On the other hand, any increase in the structure’s self-weight limits the horizontal slab’s span, increases the structure’s stress, and raises the inertia forces that must be resisted. Lightweight aggregate concrete has been effectively utilized for structural applications for a long time. The density of lightweight concrete (LWC) is sometimes more essential than its strength in structural applications. The dead load is reduced for structural design and foundations when the density is lower for the same strength level. Reinforced concrete ribbed slabs have become increasingly popular in industry construction as an alternative to solid slabs in building structures. The incorporation of steel fibers facilitates flexural softening, which takes longer than sudden brittle failure, indicating its ability to increase energy absorption and improve crack behavior. Designing structures requires materials with higher strength-to-weight ratios. Ribs and LWCs are two leading sustainable assets. The world is moving toward sustainability by reducing the amount of concrete used and the overall weight of the unit. Studies have shown that the drop in compressive strength was about 4.85–65.55%. The structural performance of lightweight fiber-reinforced concrete slabs is influenced by the concrete mix ratio, fiber type and content, reinforcement detail, and rib geometry. The study provides valuable insights into the properties and performance of key effects on the structural behavior of fiber-reinforced LWC-ribbed slabs. It provides recommendations for future research and advancement of sustainable building methods.

Enhanced energy absorption and mechanical properties of porous Ti-6Al-4 V alloys with gradient disordered cells fabricated by laser powder bed fusion

Additive manufacturing (AM) has revolutionized the production of porous metals, greatly improving control over their structural properties and offering unprecedented advantages in lightweight applications and energy absorption. Balancing energy absorption and compressive strength in ordered and disordered porous structures is challenging due to shear deformation and deformation mechanisms. This study investigates the mechanical and energy absorption properties of porous Ti-6Al-4 V alloys with gradient disordered cells fabricated using laser powder bed fusion (LPBF). The compressive response of samples with different regularities (R) and varying layers of disordered cells was analyzed through quasi-static compression experiments and finite element simulations. The results indicate that introducing a disordered cell gradient significantly enhances energy absorption by preventing the formation of shear bands observed in porous structures with ordered cell structures. When the regularity (R) is 0.8, 0.4, and 0.2 with one or two layers of disordered cells, mechanical properties are optimized and characterized by a balance between compressive strength and energy absorption. It is significant that, while preserving or enhancing compressive strength, the energy absorption of the material can be augmented substantially. Specifically, porous Ti-6Al-4 V (R = 0.8, L4) achieves an energy absorption increase of up to 154.9kJ/m³, which represents a dramatic enhancement of approximately 245.0 % over the regular porous structure (R = 0 or L0), which absorbs only 44.9 kJ/m³. Compared to ordered and disordered porous structures, the disordered cell gradient demonstrates significant potential in tuning the mechanical properties of porous metals, thereby advancing their applications in aerospace, biomedical, and protective fields.

Out-of-plane impact characteristics of missing rib-plate type anti-tri-chiral honeycomb

Chiral honeycomb structures, renowned for their superior mechanical properties, find extensive application in passive safety protection and beyond. However, existing research predominantly centers on chiral honeycomb structures, neglecting discussions on the energy absorption capabilities of anti-chiral honeycomb structures subjected to out-of-plane impacts. In view of this, an innovative design method is proposed in this paper to construct a series of anti-tri-chiral honeycomb structures (MATCH-θ) with missing rib-plate and excellent crashworthiness by skillfully designing and replacing the nodal elements of the anti-tri-chiral structures. Subsequently, the effects of the constitutive angle θ and the wall thickness t of the cellular elements were investigated using a validated finite element model, revealing the energy absorption mechanism of MATCH-θ. It is shown that this type of structure has better crashworthiness performance compared to the conventional anti-tri-chiral honeycomb structure ATCH-90°. In particular, the MATCH-110° structure with t = 0.1 mm showed a 36% increase in specific energy absorption, a 36% increase in mean crush force, and a 35% increase in crush force efficiency compared to the conventional anti-tri-chiral honeycomb structure ATCH-90° with the same mass. The completion of this study provides valuable insights into the design and optimization of future honeycomb structures for crashworthiness.
