摘要

This research thoroughly investigates the properties of fibers derived from Schumannianthus dichotomus (Patidoi) fibers (SDFs) to evaluate their suitability as reinforcements in polymer composites. The study analyses the physical, structural, chemical, thermal, mechanical, and morphological characteristics of the SDFs, comparing them with various lignocellulosic fibres. Chemical analysis revealed the presence of cellulose (52.89 ± 1.33%), hemicellulose (12.06 ± 1.22%), and lignin (27.42 ± 0.92%) in the fibers, with confirmation via FTIR analysis. XRD analysis revealed a crystallinity index of 58.11 ± 0.21% and a crystallite size of 2.15 ± 0.13 nm. Thermogravimetric analysis indicated thermal stability up to 242 ± 5 °C. The hydrophobicity of this fibre was studied using contact angle measurement, and it was found to be 97.2° ± 1°. Mechanical properties were estimated using Weibull distribution analysis, revealing a tensile strength of 192 ± 0.5 MPa and Young’s modulus of elasticity of 7.1 ± 0.06 GPa. Morphological examination via SEM and AFM analysis confirmed the presence of surface roughness, which may enhance fiber-matrix adhesion during composite fabrication. The elemental composition of the SDFs were measured using EDX. Recent scientific studies indicate that SDFs have promising potential as reinforcements in natural fiber polymer composites and biocomposites.
