“…It was discovered that adding sisal fibres to the banana-epoxy composite by 50% resulted in a reduction in moisture absorption. Amiri et al [66] investigated the influence of rapid weathering on the mechanical characteristics of flax FRPC. The mechanical characteristics of all composite samples were found to be decreasing.…”

Composites have recently emerged as the ideal material for weight reduction in a wide range of technical applications. Hybrid composites offer special properties that enable them to meet a wide range of design objectives more efficiently and affordably than conventional composites. Natural fiber-based hybrid composites are also less damaging to the environment and have a reduced carbon footprint. The hybridization of natural fibres with synthetic fibres can substantially minimise the problems associated with natural fibre composites, since the advantages of one kind of fibre can outweigh the disadvantages of another. Several research have been carried out to investigate the different characteristics of carbon-natural fibre reinforced hybrid composites and to evaluate their suitability for a variety of technological applications. The objective of this work is to provide an overview of the materials and manufacturing processes currently utilised to fabricate carbon-natural fibre reinforced hybrid composites. This paper also attempts to discuss the reported mechanical, damping, and other characteristics of the resultant hybrid composites. This article provides a factual overview of the development accomplished so far in the field of hybrid composites constructed from carbon-natural fibres.

“…1,2 Moreover, porous structures are gaining popularity to their high performance and low weight, therefore; designing porous structures of composite materials will achieve phenomenal light-weighting with maintaining high performance. 3,4 However, due to the fact, that, 70% of the earth's crust is covered with water, the physical nature of composite materials (especially the polymeric and natural composites 5 ) is making them highly susceptible to damage by water (i.e., hygral loading). [6][7][8][9] Moreover, the thermally induced mechanical load can have a significant impact on the performance of composite materials.…”

Lightweight polymeric and natural composite materials are extensively used in modern structures, especially with the demands for environmentally friendly products as well as lowering energy consumption. Furthermore, a high performance‐to‐weight ratio can be attained by utilizing porous composites. However, hygral and thermally induced loads are limiting the robustness of polymeric and natural composite materials, therefore; in this research, concurrent multiscale multiphysics topology optimization is used to design lightweight porous composite structures that have resilience toward mechanical as well as hygral and thermal loads. By establishing two independent representations of the design problem, that is, macro and microscale domains, a concurrent topology optimization framework is implemented, and the effective properties of the microscale (i.e., elastic, thermal conductivity, moisture diffusivity tensors, and hygral as well as thermal expansion coefficients) are calculated and used as the hygro‐thermo‐elastic properties of the macroscale using in‐house MATLAB codes. For hygral physics, moisture transport, as well as evaporation, are simultaneously considered in this study. A sensitivity analysis was conducted on the multiphysics concurrent optimization scheme in order to account for the coupling of macro and microstructure, as well as hygro‐thermo‐elastic physics. Multiple numerical cases were examined, which included different loading and boundary conditions, as well as various spatial configurations. The results showed attaining a high stiffness‐to‐weight ratio for the multiscale optimized porous structure compared to the single‐scale solid structure. Furthermore, a study was conducted on multiple microstructure subsystems to examine the impact of microstructure systems on macrostructure dependence. By combining several microstructures into a single macro design domain, design flexibility was enhanced and the performance‐to‐weight ratio was improved. The study was expanded to include the evaluation of hygro‐thermo‐elastic multiscale multiphysics with an evaporation problem, which was demonstrated through several numerical examples. The introduced formulations showed a successful application of the concurrent multiscale optimization formulations and good coupling on the macro and microscale. Also, the formulations demonstrated a strong influence between the macro and the microscale of the design problem for the topology optimization methods. The successful application of the concurrent multiscale optimization method in this research highlights its potential for designing more efficient and effective structures in the future.

“…Chandgude and Salunkhee [7] reported that the energy required for the production of carbon and glass fibers are 355000 and 31700 MJ/t, respectively, while the production of hemp, flax and sisal fibers requires 4170, 2752 and 2488 MJ/t, respectively. In the last decade, the production rate of NFRPCs has increased for manufacturing various interior and exterior automotive structural parts such as Audi, BMW, Toyota, etc., door panels, outdoor furniture, etc., [8,9]. It was reported in recent literature that the compound annual growth rate has been estimated at approximately 11.8% for NFRPCs during the period 2016 to 2021 [10,11].…”

Natural fiber reinforced polymer composites (NFRPCs) are being widely used in aerospace, marine, automotive, and healthcare applications due to their sustainability, low cost and ecofriendly nature. The NFRPCs manufactured through conventional, and computer controlled intelligent manufacturing techniques may contain internal and external defects. Traditionally, the microstructure of NFRPCs at different stages of manufacturing was obtained using destructive techniques which have stringent sample size restrictions and may cause decrease in residual properties of composites due to destructive scanning. However, these complications can be overcome by using non-destructive evaluation (NDE) and artificial intelligence (AI) techniques. This review highlights the impact of NDE and AI on the improvement of emerging manufacturing systems. We have discussed the classification of biocomposites, their manufacturing techniques, recyclability and strategies to improve mechanical properties. Further, the use of different types of contact and non-contact NDE techniques in understanding the microstructural variations during manufacturing, machining and the parameters that effects the mechanical performance of NFRPCs
