Abstract

In the present research, the usability of cellulosic-based fibers obtained from the Sorghum bicolor plant stem as reinforcing fibers in composites and textiles was investigated. The fibers were obtained from a Sorghum bicolor plant growing wild in the Adana region in the South of Turkey. Density, chemical structure analysis, FTIR, XRD, TGA, XPS SEM, and single fiber tensile tests characterized Sorghum bicolor fiber (SBF). SBF contains cellulose (73.6%), hemicellulose (13.3%), and lignin (12.1%). The oxygen/carbon ratio of 0.43 found as a result of XPS analysis indicates that fibers have a hydrophilic character. SBF has a 59.34% crystallinity index, 284.6 MPa tensile strength, 4.71% GPa tensile modulus, and 21.44% elongation at break. The maximum degradation temperature of the fibers was determined as 364.22 °C. Sorghum bicolor fiber, through detailed characterization, emerges as potential promising reinforcement for the composite industry with relatively good strength and high cellulose content for the textile industry.
