Abstract
This study investigates the potential of Dracaena draco fiber (DDF) as a viable option for the development of biodegradable natural composites, with the objective of making a valuable contribution to the field of environmentally sustainable materials. This study presents a comprehensive investigation into the morphological, thermophysical, and mechanical properties of DDF. The findings indicate an average density of 1.2043 g/cm3, a linear density of 18.87 Tex, and moisture recovery and moisture content values of 12.88 % and 11.54 %, respectively. These results represent the first full examination of these parameters for DDF. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) examinations offer valuable information regarding the crystallinity and functional groups present in DDF. These analyses reveal a crystallite size of 3.14 nm and a crystallinity index of 30.42 %. The TGA analysis indicates that the DDF fiber exhibits a consistent temperature of 329.5 °C. The behavior of a material can be effectively demonstrated through the exact modeling of water absorption, as exemplified by the models developed by Sikame et al. The mechanical testing results reveal that DDF has an impressive average yield strength of 553 MPa, a strain at rupture of 2.5 %, and a Young's modulus of 24.9 GPa. In this study, we utilize ML estimation and statistical analysis based on the two-parameter Weibull distribution to conduct a thorough assessment of the mechanical properties of DDF. The comparison of DDF with other natural fibers discussed in the available literature establishes its potential as a suitable reinforcement for lightweight biocomposites. This makes it a feasible option for various applications that involve thermoplastic or thermosetting polymers. The aforementioned results highlight the potential of DDF in the development of sustainable materials for a wide range of industrial applications.
