These days, natural fibers are used extensively as reinforcement in biocomposites because of their valuable characteristics, which include biodegradability, non-toxicity, and lightweight. Bagasse, halfa grass, and coir natural fibers are high-cellulose fibers that are cheap and abundant in India. The fibers from bagasse, halfa grass, and coir were extracted and treated with 5% NaOH. The properties of untreated and alkali treated fibers were investigated, and experimental determinations were made for their mechanical, thermal, chemical, and morphological properties, including tensile strength, thermogravimetric analysis (TGA), scanning electron microscope (SEM), and Fourier transform infrared spectrometry (FT-IR). A comparative study of untreated and treated fibers was carried out. It is interesting to note that coir fiber possesses significant high tensile of 183 MPa and thermal properties (31% of weight retention at 600 °C) than the others. FT-IR analyses were carried out to ascertain the chemical composition of three raw and alkali-treated fibers. The morphological examination of all three alkali-treated fibers using a SEM interpreted the removal of pollutants on the surface of the treated fibers. This study interprets that alkali-treated coir fiber possesses significantly better mechanical properties compared to other two fibers. [ABSTRACT FROM AUTHOR] |
