“…• The delayed formation of cracks in both non-loaded and preloaded beams indicates that the incorporation of natural fibre composites effectively strengthened the beams and contributed to enhanced structural performance. The beams also exhibited improved load-deflection behaviour, suggesting that the composites effectively distributed and dissipated the applied load, further enhancing their load-carrying capacity [9]. • The crack pattern analysis revealed that the retrofitted beams displayed a ductile behaviour, exhibiting significant deformation before failure.…”

In response to the growing demand for eco-friendly construction materials, natural fibers such as bamboo and jute have emerged as viable alternatives to traditional options like steel and concrete. These natural fibres offer several advantages, including high tensile properties, crack resistance, and moisture resistance, making them suitable for structural applications. This study explores the potential of bamboo textile-based composite and jute textile-based composite for retrofitting reinforced concrete beams. It was found that the 4-layer bamboo textile composite achieved a 50% increase in tensile strength and similarly, the 5-layer jute textile composite demonstrated a significant 90% increase in tensile strength. In this study, the optimized 4-layer bamboo textile and a 5-layer jute textile composite with are applied in a U-wrapping configuration for retrofitting purposes. Strengthened and preloaded beams were retrofitted and subjected to testing for comparison. The results indicate that the bamboo textile composite outperforms in terms of both strengthening and retrofitting applications.

“…Each year, the plastics sector uses several billion pounds of fillers and reinforcements. With enhanced compounding technology and novel coupling agents that allow for higher filler/reinforcement content, the utilization of these natural fibers in polymers is projected to increase [49][50][51][52][53][54]. The sustainable manufacturing of the eco-compatible products may become more widespread in the future, perhaps reducing the need for petroleum-based polymers significantly [55][56][57][58].…”

Natural fiber-reinforced polymer composite is a rapidly growing topic of research due to the simplicity of obtaining composites that is biodegradable and environmentally friendly. The resulting composites have mechanical properties comparable to synthetic fiber-reinforced composites. In this regard, the present work is formulated with the objectives related to the development, characterization, and optimization of the wt% of reinforcements and the process parameters. The novelty of this work is related to the identification and standardization of the appropriate wt% of reinforcements and parameters for the processing of the areca nut leaf sheath fiber-based polymer composites for enhanced performance attributes. With this basic purview and scope, the composites are synthesized using the hand layup process, and the composite samples of various fiber compositions (20%, 30%, 40%, and 50%) are fabricated. The mechanical characteristics of biodegradable polymer composites reinforced with areca nut leaf sheath fibers are investigated in the present work, with a focus on the effect of fiber composition (tensile properties, flexural strength, and impact strength). The properties of composites are enhanced by combining the areca nut leaf sheath fiber and epoxy resin, with a fiber content of 50% being the optimal wt%. The Scanning electron microscopy (SEM) investigations also ascertain this by depicting the good interfacial adhesion between the areca nut leaf sheath fiber and the epoxy resin. The tensile strength of the composite specimen reinforced with 50% areca nut fiber increases to 44.6 MPa, while the young’s modulus increases to 1900 MPa, flexural strength increases to 64.8 MPa, the flexural modulus increases to 37.9 GPa, and impact strength increases to 34.1 k J/m2. As a result, the combination of areca nut leaf sheath fiber reinforced epoxy resin shows considerable potential as a renewable and biodegradable polymer composite. Furthermore, areca nut leaf sheath fiber-reinforced epoxy resin composites are likely to replace petroleum-based polymers in the future. The ecosustainability and biodegradability of the composite specimen alongside the improved mechanical characteristics serve as the major highlight of the present work, and can help the polymer composite industry to further augment the synthetic matrix and fiber-based composites with the natural fiber-reinforced composites.
