Abstract

Global warming solutions in the modern era are centered on substituting environmentally friendly biodegradable materials for fossil fuels to slow down the rate at which they are being depleted. The study literature supports the use of substitute materials for plastics in the creation of composite materials, and this work envisions the use of Calotropis gigantea fruit bunch fiber as one such substitute material. Since Calotropis gigantea fruit bunch fiber is widely available in Bangladesh and has little vegetation value, it was selected for this project. Three chemical pretreatments are applied to the Calotropis gigantea fruit bunch fiber: sodium hydroxide (alkali treatment), hydrogen peroxide (peroxide treatment), and benzoyl chloride (benzoylation). Chemically treated fibers are used to form composites, and their mechanical properties are examined. Compared to all other composites, benzoylated composites have superior tensile, compressive, and impact strengths. It has been shown that the benzoylation increased the composites’ tensile strength by 98.3%, compressive strength by 61.4%, and impact strength by 97.7% when compared to the untreated and benzoylated versions. The composite treated with hydrogen peroxide has more flexural strength than any other composite. A treatment with hydrogen peroxide increased the flexural strength by 44.5%. Hydrogen peroxide treatment increased the composite’s elongation capacity during tension, flexure, and compression tests, despite the composite’s flexural strength being somewhat lower than that of the benzoylated composite. Benzoyl chloride appears to be the most effective chemical treatment when considering overall performance. The surface morphology of the benzoylated composite revealed a few defects.h by 97.7% when compared to the untreated and benzoylated versions.
