Description
Summary:Embarking on a pioneering investigation, this study unravels the extraordinary qualities of Tecoma stans Fibers (TSFs), freshly harvested from the rachis, establishing them as prospective reinforcements for biocomposites. Delving into their intricate characteristics, TSFs exhibit a unique fusion of physical resilience, with a density of 1.81 ± 0.39 g/cc and a diameter of 234.12 ± 7.63 μm. Complementing their physical prowess, their chemical composition boasts a harmonious blend of cellulose (70.1 ± 9.06 wt%), hemicellulose (13.56 ± 4.29 wt%), lignin (7.62 ± 2.39 wt%), moisture (4.21 ± 1.56 wt%), wax (2.37 ± 0.63 wt%), and ash (1.25 ± 0.36 wt%). In the realm of mechanical strength, TSFs showcase an impressive tensile strength of 639 ± 18.47 MPa, coupled with a robust strain at failure of 1.75 ± 0.13 % and a Young Modulus of 36.51 ± 1.96 GPa. Unveiling their crystalline intricacies, these fibers reveal a microfibril angle of 14.66 ± 0.15°, a crystalline index (CI) of 63.83 %, and a crystallite size (CS) of 9.27 nm. Beyond their mechanical marvels, TSFs exhibit unwavering thermal stability, enduring temperatures up to 297.36 °C, with a Tmax reaching an impressive 392.09 °C.
