“…The reinforcement of CaCO 3 ultimately improved the mechanical properties; precisely, the composites' compression strength, flexural strength, and impact strength. In addition, the higher melting point of the CaCO 3 showed better thermal stability, as confirmed by TGA analysis [23].…”

Natural fiber-reinforced composites can contribute to reducing carbon footprint goals due to their ability to reduce overall product weight, bio-diverse feedstocks, and recyclability potential. In this work, natural fiber-based composites containing the reinforcement of coconut husk and bagasse fiber with calcium carbonate (CaCO3) ingredients were prepared and analyzed. The composites were analyzed for mechanical, thermomechanical, and morphological properties. The reinforcements were chemically functionalized using 5% w/v NaOH to enhance their interactions with the epoxy resins. The chemical functionalization created perforation on the fiber surface, improving the interlocking of fibres with the resin material and strengthening the mechanical performance of the composite. The composites developed using modified reinforcement treatment resulted in increased tensile strength (64.8%) and flexural strength (70%). The reinforcement treatment influenced the hydrophilicity, and the water absorption of treated composites was reduced more than five times compared to the unmodified composites. Scanning electron microscopy revealed morphological changes due to fiber modification, the underlaying mechanism of fiber contraction, and enhanced fiber matrix interface interlocking and adhesion strengthening. Thermal analysis confirmed that alkali treatment improves the crystallinity of the fiber and thereto the degradation temperature of treated fiber composites (both bagasse and coconut husk), which is 375.27 °C, the highest amongst the developed hybrid composites.

“…Therefore, natural fiber-based materials have the potential to be a cost-effective, technologically viable, and appealing alternative to synthetic fiber composites in industrial applications. [1][2][3] Whenever the two natural fibers are hybridized, the mechanical properties will not improve significantly. Therefore, much research is going on with hybridizing the natural fibers with the synthetic fibers which helps in replacing the synthetic fibers to some extent with better properties.…”

The recent developments and technological advancement in material science focus on the utilization of biodegradable material in various engineering applications. The increase in concern for the damages happening by synthetic materials has made the researchers develop novel materials that can reduce the use of synthetic materials to minimize the environmental problem and societal anxiety. In this work, the four‐layered areca/carbon/kevlar/carbon–kevlar hybrid fiber‐reinforced epoxy laminates were prepared by using hand layup technique for seven different stacking sequence. The prepared laminates were evaluated for mechanical, thermal, and water absorption behavior to study the hybridization effect on the properties of the composites. The result indicated that areca/carbon composites had better mechanical properties than areca/kevlar, areca/carbon–kevlar hybrid laminates. Hybridization of areca fiber with synthetic fibers had significant effect on the mechanical properties of the composites. The water absorption behavior and thermal property of the laminates improved with addition of synthetic fibers to areca fiber. Morphological analysis showed strong bonding with fibers and reinforcements, with fewer voids. Therefore, the developed areca/synthetic fiber hybrid composites can be used for semi‐structural engineering applications.

“…Increased environmental awareness together with the aim of limited hazardous gaseous emissions across the globe and the urge for the development of a newer class of materials from renewable resources has led to the invention of natural fibers derived from plants and their reinforcement in polymer composites. [1][2][3][4][5] Natural fibers as a reinforcement in polymer or other bio-based composites have led to the development of more commercial products and have found their presence elsewhere with a wide range of applications in diverse fields. [5][6][7][8][9][10][11][12] Since the inception of the 20th century, metallurgists, scientists, and professors across the globe have been inspired highly in employ natural fibers rather than synthetic fibers as an ideal reinforcement in polymer composites due to their numerous unique attributes such as light-weight, lesser cost, abundance in availability, less dense, reduced hazardous gas emissions, eco-friendly, ease in fabrication, biodegradable and sustainable.…”

The prime objective of this research study was the investigation the new natural cellulosic fiber extracted from the stem of Abutilon Indicum plants as an alternative reinforcement in greener composite materials for structural applications. Abutilon Indicum a flowering plant with unique medicinal values are abundantly found in India and other south Asian countries. The fibers extracted from the stem of the Abutilon Indicum plant are proven to be sustainable, ecofriendly, and novel and hence this fiber is chosen for characterization study. In this experimental investigation the physical, chemical, thermal, morphological, crystallinity, chemical constituents, and surface characteristics of raw Abutilon Indicum fibers (AIF) were analyzed. Chemical analysis results convey the presence of higher cellulose content of (56.12 wt.%) in AIF. The diameter (175 μm) and density (1.170 g/cm3) of AIFs are determined by physical analysis of the raw fibers. Such lower density values observed in AIF make it as a perfect material for lightweight applications. Crystalline properties of AIFs are determined from X‐ray diffraction tests with a crystalline index of 77.35%, and crystalline size of 2.20 nm, which attributes to the presence of cellulose‐1β and the crystallites are ordered in nature. Thermal stability of 175°C, maximum degradation temperature upto 302.6°C and kinetic activation energy of 86.95 kJ/mol of AIF are established based on thermo gravimetric analysis. Morphological and surface characteristics of AIF through a scanning electron microscope (SEM) and atomic force microscope (AFM) analysis revealed that the raw fibers display a relatively finer surface. Research findings of the AIF mentioned above conclude that the AIFs prove to be an ideal, alternative reinforcement in greener composite materials for sustainable and cleaner production of components in structural applications.
