In fiber metal laminates (FMLs), the order in which fibers with different natural properties are stacked is very important for making materials that absorb vibrations and have good mechanical properties for structural applications. Hence, the present study focuses on the mechanical and vibration characteristics of FML designed with multi‐order energy‐absorbing flax fiber and high‐strength basalt fiber stacking covered with titanium sheets. The fabricated FMLs were designed with titanium/basalt fiber laminate (Ti/B), titanium/flax fiber laminate (Ti/F) and titanium/multi‐order‐flax‐basalt fiber laminate. The mechanical characteristics including tensile, flexural, and impact strength; and vibration characteristics of prepared FMLs were investigated. The higher tensile and flexural strength were revealed in an FML consisting of basalt layers (Ti/B) laminate than the flax core part (Ti/F) due to the strongness of basalt fiber, increasing the capability of load‐bearing of composites. Ti/B FML showed a maximum tensile strength and flexural strength of 412 and 450 MPa. Furthermore, flax fiber absorbs more energy, so the flax layer's inbuilt structure increases energy absorption during impact and vibration testing. Ti/F exhibits the highest impact strength (427.8 kJ/m2) and Ti/B exhibits the lowest impact strength (312.5 kJ/m2) because flax fibers are more ductile than basalt fibers, increasing the toughness of the FML. Ti/F FML structure, the greatest natural frequency of modes 1, 2, and 3 (549.03, 715.07, and 956.15 Hz) was observed. Natural fiber hybridization designed for FML, such as the Ti/B/F laminate, improved mechanical and vibration properties, making it suitable for structural applications.Highlights Fiber metal laminates were designed with titanium/flax/basalt. FMLs stacked composites significantly affect the mechanical properties. The basalt fiber, increases the capability of load‐bearing of FMLs. The damping of FMLs increases with the increase in flax fiber layers. Flax‐basalt fibers stacked FMLs produce tunable impact and vibration energy.

This work deals with the prediction of tribological performance in (Mg2Si-TiB2)/A356 composites. In this work tribological properties are also correlated with topographical characteristics. The effect of several input factors such as load, sliding distance and TiB2 wt.% on tribological characteristics of (Mg2Si+TiB2)/A356 composites was explored by Response Surface Methodology (RSM). Central composite design (CCD) with three input factors and three level of variables in RSM was used to develop a statistical model. RSM suggests quadratic model to express a mathematical relationship between input factors to assess wear rate and coefficient of friction (COF). Analysis of variance (ANOVA) was applied to investigate the influence of input factors on wear rate and COF and found that most significant variable which influence wear rate and COF is applied load followed by TiB2 wt.% and sliding distance. The desirability function approach is applied to optimized input variables to minimize wear rate and COF. Optimum wear rate is noticed at input variables of 26 N load, 2766 m sliding distance and 3.36wt.% of TiB2 and optimum COF was observed at 29 N of load, 2233 m sliding distance and 1wt.% of TiB2. A confirmatory test was conducted to validate the developed model and observed that experimental results matched the predicted value with error less than 5 %. SEM and AFM examined surface topography of wear surfaces to understand the wear mechanism and surface features at various input factors. Microstructural features were also examined under optical microscope and SEM, revealing that increased TiB2 content in hybrid composite refine primary Mg2Si and eutectic Mg2Si phase and results in increased hardness and improved tribological behaviour of hybrid composite.

Laminated metal‐composite structures, known as fiber metal laminates (FMLs), are modern lightweight materials extensively utilized in diverse industries such as aerospace and automotive manufacturing. These materials offer enhanced impact and fatigue resistance, making them invaluable for various applications. However, machining FMLs poses a challenge due to the occurrence of delamination and heterogenous in nature during conventional methods. Therefore, this study aims to investigate the quality characteristics such as kerf width, surface roughness and kerf taper of Magnesium based FMLs processed with an unconventional machining process namely abrasive water jet cutting (AWJC). These FMLs comprise alternately stacked kevlar/carbon fibers adhesively bonded with epoxy resin matrix filled with varying wt% of reduced graphene oxide (r‐GO), combined with AZ31B alloy sheet as the skin material. AWJC experiments were performed by varying the process parameters including waterjet pressure (275–325 MPa), stand‐off distance (2.5–3.5 mm), and cutting speed (600–800 mm/min) based on the box–behnken experimental design. The findings from the statistical analysis underscore the significant influences of stand‐off distance and waterjet pressure on kerf characteristics, while the inclusion of r‐GO is observed to notably affect the surface quality. In pursuit of enhancing cut quality, a multi‐response optimization was conducted employing the Gorilla Troops Optimization (GTO) algorithm. Comparative analysis with established metaheuristics like the gray wolf algorithm, dragonfly algorithm, and harmony search algorithm reveals GTO's superior performance across various metrics, including rapid convergence, diversity, and spacing values. Further, the cutting‐induced damages such as matrix plowing, fiber‐metal debonding and composite delamination were observed through microstructure analysis.Highlights Magnesium (AZ31B) fiber metal laminate comprising with various wt% of reduced graphene oxide was fabricated. Abrasive waterjet cutting of FMLs were performed based on box–behnken design experimental approach. Statistical analysis and influence of process parameters on the kerf width, surface roughness and kerf taper were investigated. Multi‐response optimization was carried out using metaheuristic‐based gorilla troops algorithm.
