“…According to this finding, sodium bicarbonate treatment reduced SRF hydrophilicity and enhanced fiber adhesion to matrix, preventing the formation of microvoids or gaps within the biocomposites. As a result, PCL/10TSRF had a significantly lower water gain percentage than PCL/10USRF [10]. At remaining fiber loadings of 15, 20, and 25 wt.%, respectively, PCL/USRF and PCL/TSRF biocomposites have comparable water gain percentages.…”

“…The treated fiber was then washed with deionized water to completely remove the NaHCO3 left over on the surface of SRF. Finally, the chemically treated SRF was dried in the convention oven at a temperature of 40°C for 24 hours [10]. The dried and treated SRF are shown in Fig.…”

“…A slight increase in Strain (%) value has been observed for PCL/TSRF bio composites when compared to PCL/USRF bio composites. As a result of the chemical treatment, the ductility property of SRF was marginally enhanced by rearranging the fibrils in the fiber [10].…”

“…In summary, Sesbania rostrata fibers (SRF) are widely available locally and can be used for composite reinforcement purposes for a variety of reasons. Only a few studies have been conducted on the fiber [9,10]. This article examines the effect of reinforcement of sodium bicarbonate-treated and untreated SRF with PCL at different weight proportions (10, 15, 20, and 25 wt.%) on mechanical, thermal, water absorption, and tribology (specific wear rate) in order to discover SRF reinforced polycaprolacton biocomposite for engineering applications.…”

The best way to accelerate the application of polymer composites is by making them an environmentally friendly material that can degrade naturally without harming the environment. Hence, this work focuses on the development of biocomposite by reinforcing bark fibers of Sesbania rostrata (SRF) with polycaprolactone (PCL) biopolymer. Composite samples were fabricated by reinforcing untreated SRF and sodium bicarbonate-treated SRF to PCL at different weight proportions of 10, 15, 20, and 25%. The compressing moulding technique was used to develop the test specimens, and samples were subjected to mechanical, thermal, water absorption, wear, and morphological tests. Biocomposites made of 20 wt.% of chemically treated SRF with PCL yield better mechanical strength than other combinations. The thermal properties of biocomposite were not affected by the inclusion of untreated fibers and were improved by the inclusion of treated fibers. An increased fiber volume fraction in the biocomposites accounts for higher water absorption properties, whereas chemically treated fibers show a significant increase in water resistance. Wear test results expose that the weight loss of the biocomposites is mainly dependent on the contact temperature and adhesion between the SRF surface and the PCL matrix. Scanning Electron Microscope (SEM) analysis of the fractured biocomposites reveals that failure occurs primarily due to fiber pull-out, debonding, and agglomeration.

This study presents an extensive survey of the many surface treatments that may be given to natural fibers for use in advanced composites. When put into reality, the primary disadvantages of working through biological fibers are the increased level of moisture intake that natural fibers possess as well as their low dimensional stability. The fundamental purpose of applying surface treatments to natural fibers is to optimize the bonding strength as well as the pressure transferability in composites made of biological natural fibers. Natural fiber-strengthened polymer composites (NFPC) have overall mechanical qualities that are strongly dependent on the morphological, aspect ratio, hydrophilic propensity, and high stiffness of the natural fibers that are employed in the composite. Cellulosic fibers are being studied for their effects both before and after being used as reinforcements for thermoset and thermoplastic polymers. Some of the chemicals utilized in treatments include alkalis, silane, acetyl, benzoylation, acrylation and polyamide grafting, maleated linking agents, ammonium nitrate, peroxide, phenoxy, stearic acid, potassium chalcopyrite, triazine, synthetic derivatives of fatty acids (oleoyl chloride), and fungi. After chemical treatment, composites made from organic fibers are stronger and more dimensionally stable than the untreated sample.

An efficient method to accelerate the use of polymer composites is to focus on their development as environmentally friendly materials that can naturally break down without causing any harm to the ecosystem. Hence, the primary aim of this study is to develop a biocomposite material through the fusion of Sesbania rostrata (SRF) bark fibers and the polycaprolactone (PCL) biopolymer. Various percentages (10, 15, 20, and 25 wt.%) of untreated and sodium bicarbonate‐treated SRF were incorporated into polycaprolactone to create the biocomposite samples. The composite panels were made using the compressing molding technique. Several tests were performed on the samples, such as mechanical, thermal, water absorption, wear, and morphological tests. Research has demonstrated that the strength of biocomposites composed of 20% chemically treated SRF and PCL is superior to that of other mixed materials. The thermal properties of the biocomposite remained unchanged when untreated fibers were included, but they improved when treated fibers were included. Higher water absorption properties are attributed to an increased fiber volume fraction in the biocomposites, while chemically treated fibers exhibit a notable improvement in water resistance. The wear test results indicate that the weight loss of the biocomposites is mainly influenced by the contact temperature and adhesion between the SRF surface and the PCL matrix. When examining the fractured biocomposites with a scanning electron microscope (SEM), it becomes evident that the primary reasons for failure are fiber pull‐out, debonding, and agglomeration.Highlights SR Natural fiber is chemically treated by eco‐friendly sodium bicarbonate. The treated SRF‐reinforced composites had best mechanical property. The treated SRF‐reinforced composites showed less water absorption. The composite mechanical and thermal properties had dropdown at 25 wt.% SRF. The addition of SRF reduced the weight loss of composites on wear test.
