 Researchers explored the properties of Yucca treculiana, YT, fiber for use in biodegradable biocomposites, finding it to have a density of 1.330 plus or minus 0.039G, CM3, and chemical analysis of 82.3%, 12.1%, and 5.6% for cellulose, hemicellulose, and lignin, respectively. The surface chemistry, crystallinity, and functional groups of YT fibers were analyzed by XBS, XRD, and FDIR, respectively. The concentration levels of carbon, 62.88%, and oxygen, 33.72%, were detected by XBS. XRD analysis showed that the YT fiber has a crystallite size of 3.02 nanometers and a crystallinity index of 48.85%. Based on thermal analysis by TGA, the results show thermal stability of the YT fiber up to 360.6 degrees Celsius. The average mechanical properties of the fiber are 222 MPa for the tensile strength, 2.47% for the strainer break and the Young's modulus is equal to 16.85 GPA. These results prove that YT fiber can be used as reinforcement in making lightweight industrial biocomposites with thermoplastic or thermosetting polymers.
