Comprehensive Characterization of New Natural Fiber Extracted from the Stem of Grewia flavescens Plant

ABSTRACT

The physical, chemical, mechanical, thermal, and morphological characteristics of Grewia flavescens are reported in this article. The G. Flavescens fiber is found to have a satisfactory cellulose content and can be useful for lightweight applications due to its lower density. The fiber was analyzed using X-Ray diffraction (XRD) analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy, scanning electron microscopic test, and atomic force microscopy. While XRD analysis confirms a comparable crystallinity index for this natural fiber, the thermal characteristics confirm the fiber’s stability behavior when subjected to temperatures up to 165°C. Results of the morphological study of the fiber with a rough surface suggest its suitability for use in making composites. The comparatively less amount of wax and moisture content observed are again advantageous as the fiber bonding with the matrix will be improved in the composites. It is recommended that the present G. flavescens fiber can be efficiently utilized for making biocomposites.

摘要

本文报道了苦参的物理、化学、力学、热学和形态特征. 研究发现,黄曲霉纤维具有令人满意的纤维素含量,并且由于其密度较低,可用于轻质应用. 利用X射线衍射(XRD)分析、热重分析、傅里叶变换红外光谱、扫描电子显微镜和原子力显微镜对纤维进行了分析. 虽然XRD分析证实了这种天然纤维的可比结晶度指数'但热特性证实了纤维在温度高达165℃时的稳定性. 纤维表面粗糙的形态研究结果表明,它适合用于制造复合材料. 由于复合材料中纤维与*基体的结合将得到改善, 因此观察到的相对较少的蜡含量和水分含量也是有利的. 建议将现有的黄曲霉纤维有效地用于制备生物复合材料.
