This paper proposes an optimisation method for fabricating composite materials and functionally graded structures. Using the proposed method, 3D printing of copper (Cu)–polyethylene (PE) composite, Al 2 O 3 –ZrO 2 ceramic composite and functionally graded CuO foams are utilised. This work aims to advance the capabilities of additive manufacturing by leveraging nature‐inspired approaches to create complex, tailored structures with enhanced performance across various industries. The major objective of the proposed method is to reduce the feed rate and increase the airflow rate and airflow temperature for the heat transfer process. Using the proposed technique in the advanced preparation conditions, Cu–PE composites with unreliable Cu substances are fabricated. The PE binder particle is melting as well as forming thick composites by means of soft surfaces. Using the proposed AHO approach, functionally graded materials with common distributions can be efficiently optimised. By then, the proposed model is implemented on the MATLAB platform, and its execution is calculated using the current procedures. The proposed technique displays superior outcomes in all existing methods like wild horse optimiser, particle swarm optimisation and heap‐based optimiser. The proposed method shows a throughput of 57 mm ³ . The existing method shows the throughput of 32, 27 and 45 mm ³ . The results show that the proposed method has higher throughput compared with existing methods.

Bio-composite materials are gaining momentum as eco-friendly substitutes for synthetic fiber-reinforced composites across various sectors. This study investigates how varying fine powder loads affect the tensile, transverse, and compressive properties of hybrid composites comprising Malabar Ironwood sawdust and COCO dust particles. A hybrid composite formulation was devised using a 1:1 ratio of sawdust and COCO dust particles as fillers. Different levels of reinforcement, ranging from 20% to 60%, were examined. ASTM testing was performed on the produced composites, revealing a notable influence of filler reinforcement on their mechanical characteristics. The elongation at fracture increased until 40% filler loading before declining, whereas tensile strength, transverse rupture strength, transverse modulus, and compressive strength consistently improved up to 50% filler loading. These results underscore the potential of composites integrating Malabar Ironwood, COCO dust, and epoxy for lightweight applications, thereby catering to diverse industries seeking sustainable alternatives to traditional materials. Ultimately, such initiatives contribute to solid waste management efforts, offering sustainable alternatives to conventional materials in diverse industries.

In this work, the effects of graphene particles, which were used as a filler for hybrid flax fiber and aerial root banyan fiber (ARBF)–reinforced epoxy composites at different sampling compositions (M4–M7), on the physical and mechanical characteristics of the epoxy composites, such as tensile, flexural, Shore D hardness, water absorption activities, and morphology were studied. The accumulation of graphene particles improved the tensile strength, flexural strength, and hardness but significantly decreased the percentage of water absorption. The ideal ratio of fibers and graphene particles for improved epoxy hybrid epoxy composites is also discussed in this study. The presence of graphene in flax/Banyan/epoxy composites acts as a flame retardant, and the combustibility decreases as the graphene level rises. The best mechanical property value was obtained with 2% graphene particles in the 19% ARBF, 19% flax fiber with 60% (M4 constituent) epoxy-reinforced hybrid composites. The results showed that a hybrid composition of 2% graphene content plays an important role and improves the strength of the hybrid composite.

... Hybrid polymer composites represent a groundbreaking advancement in material science, offering a synergistic combination of different reinforcing components within a polymer matrix (Prashanth et al. 2017;Santulli et al. 2023;Gurusamy et al. 2024). By incorporating various reinforcements, such as fibers, particulates, or nanoparticles, hybrid polymer composites have the potential to achieve enhanced mechanical strength, improved toughness, superior thermal stability, and tailored electrical or magnetic properties. ...

... KP-1.5, and KP-2.0 composites increased by 90.24%, 85.58%, and 34.21%, compared to neat composites. Ganapathy et al. 43 reported that the addition of 2 wt% graphene had enhanced the flexural strength of the banyan/flax fiber composite by 41%. They also reported that adding a higher weight concentration of graphene (4, 6, and 8 wt%) has reduced the loading carrying ability due to aggregation. ...
