ABSTRACT

This current study focuses on the suitability evaluation of cellulose fibers from the stem of Albizia julibrissin (AJ) plant. Density, Diameter, chemical constitutions, thermal degradation nature, crystallinity and topographical properties of AJF was evaluated. The results concluded that the cellulose percentage was higher with 55.83 wt. % with a lower percentage of lignin (16.03 wt. %) and hemicellulose (10.74 wt. %) for AJ fibers. The X-Ray diffraction analysis revealed that the crystallinity index value of the proposed fiber is 27.77% and the crystalline size is 6.79 nm. The thermo gravimetric analysis showed excellent stability with a char residue of 25.23% and a maximum degradation temperature of 330°C. Based on the outcomes in comparison with other cellulose fibers, it is proved that AJ fibers could be effectively used as reinforcement in the manufacturing of lightweight composites.

摘要

本研究的重点是合欢茎中纤维素纤维的适宜性评价(AJ) 工厂。评估了 AJF 的密度、直径、化学成分、热降解性质、结晶度和形貌特性。结果得出结论，纤维素百分比较高，为 55.83 wt. %，对于 AJ 纤维，木质素 (16.03 重量%) 和半纤维素 (10.74 重量%) 的百分比较低。X射线衍射分析表明，该光纤的结晶度指数值为27.77%，结晶尺寸为6.79 nm。热重分析显示出优异的稳定性，炭残留量为 25.23%，最高降解温度为 330°C。基于与其他纤维素纤维的比较结果，证明AJ纤维可以有效地用作制造轻质复合材料的增强材料。
