Abstract
The purpose of this study is to characterize alkali-treated fibers from the prop root of fragrant screw pine (FSP) plant in order to determine their suitability as a substitute for man-made fiber in preparation of lightweight bio-based composite materials. The physical, chemical, mechanical, morphological, and thermal properties of alkali-treated FSP fibers (AFSPF) were reported and compared to those of other natural fibers used as reinforcement in polymer composites. Cellulose content (80.53 wt.%), wax content (0.21 wt.%), density (1.41 g/cm3), tensile strength (619–1038 MPa), and young’s modulus (23–41 GPa) of AFSPF were determined. Thermal analysis (TGA and DTG) confirms the thermal stability of these fibers up to 257°C. The characterized properties demonstrate that AFSPF can be used as reinforcement in the preparation of polymer-based bio-composites for applications requiring low weight and high specific strength that meet technical and environmental requirements.
