Understanding the characteristics of Cordia dichotoma fibers (CDf) is essential for optimizing treatment and enhancing performance in composites. This study examines CDf's mechanical, thermal, and morphological properties after treatment with NaOH, NaClO₂, and a combined treatment (NaClO₂ followed by NaOH). NaOH-treated fibers (CDf-NH) exhibited the highest tensile strength (152.8 MPa), crystallinity index (127.57 %), and thermal resistance (up to 380 °C). The combined treatment provided optimal physical and chemical characteristics, enhancing CDf's potential in sustainable composites. These findings support chemical treatments for improving natural fibers in composite applications. © 2024 The Authors
