Physical, Chemical, Thermal, and Surface Morphological Properties of the Bark Fiber Extracted from Acacia Concinna Plant

ABSTRACT

This research aimed to assess the fitness of fiber collected from the bark of Acacia concinna (AC) plant for composite reinforcement. Chemical analysis report exposed that ACF has the cellulose and hemicellulose content of 59.43 wt. % and 12.78 wt. %, respectively. Different chemical compositions and relevant functional groups existing in the ACF were identified thought the Fourier Transform-Infrared (FTIR) Analysis. Crystallinity index (27.5%) and crystalline size (4.17 nm) of the ACF were calculated by the X-ray diffraction analysis. Surface of the ACF was investigated with the aid of Scanning electron microscope (SEM) and Atomic force microscope (AFM). Comparatively higher thermal stability (225°C), kinetic activation energy (69.33 KJ/mol) and lower density (1365 kg/m³) of ACF are the required assets for reinforcement in the polymer matrix.

摘要

本研究旨在评估从Acacia concinna（AC）植物树皮中收集的纤维是否适合进行复合增强。化学分析报告表明，ACF的纤维素和六纤维素含量分别为59.43wt.%和12.78wt.傅立叶变换红外（FTIR）分析认为，ACF中存在的不同化学成分和相关功能组是被强化的。晶体指数 （27.5%）通过X射线衍射分析计算ACF的晶体尺寸（4.17nm）. 利用扫描电子显微镜（SEM）和原子力显微镜（AFM）对ACF表面进行了研究. 相对较高的热稳定性（225°C）、动能活化能（69.33 KJ/mol）和低密度（1365 kg/m3）是聚合物基质中增强的必要资产.
