Exploring the Potential of Underutilized Zingiberaceae Fibers: A Study on <i>Meistera aculeata</i> and <i>Amomum andamanicum</i>

This study presents the first comprehensive characterization of fibers extracted from two novel species belonging to Zingiberaceae family: Meistera aculeata (MAF) and Amomum andamanicum (AAF). Physical, chemical, thermal, and mechanical properties were evaluated using FTIR, TGA, XRD, and tensile testing. MAF exhibited a 4.7% higher cellulose content, enhanced crystallinity, improved fiber alignment, and reduced moisture absorption compared to AAF. These attributes contributed to superior mechanical performance, with tensile stress values reaching 1418.42 MPa for MAF and 970.00 MPa for AAF, along with higher tensile modulus and lower tensile strain. In this study, AFM provided detailed surface roughness and topography, SEM revealed structural features along with fracture study, and EDX identified elemental composition, collectively offering a comprehensive insight into the fibers’ morphology and suitability for composite reinforcement. The results underscore the potential of these fibers for high-performance engineering applications. Furthermore, the study offers a sustainable solution for managing pseudostem biomass waste, aligning material innovation with environmental stewardship. By unveiling the structural merits of these underutilized fibers, the research paves the way for their integration into advanced bio-composite development.
