Physico Chemical Characterization of Fiber from Melia Azedarach Barks as an Effective Reinforcement in Polymer Matrices

ABSTRACT

The present study aimed to investigate the physico-chemical properties of new cellulosic fiber obtained from the bark of Melia Azedarach tree. The investigation outcomes revealed that, the cellulose content, crystallinity index and density of Melia Azedarach Fiber (MAF) were determined as 66.5 wt.%, 45.45% and 950 Kg/m³, respectively. The MAF had thermal stability up to 220^θC which is evidenced from the thermo gravimetric analysis. The Fourier Transform Infra Red test clearly specified the existence of cellulosic and non-cellulosic substance in MAF. The morphological analysis showed that MAF contains smooth surfaces and its diameter is measured as 48.2 ± 2 µm. The results of this investigation on MAF were evident that it can be used as future reinforcement material to develop the green composite for potential applications.

摘要

研究了从苦楝树皮中提取的新型纤维素纤维的理化性质. 结果表明，苦楝纤维（MAF）的纤维素含量为66.5%，结晶指数为45.45%，密度为950kg/m3. 热重分析表明，MAF的热稳定性高达220θC. 傅立叶变换红外试验清楚地说明了MAF中存在纤维素和非纤维素物质. 形态分析表明，MAF具有光滑的表面，其直径为48.2±2µm. 研究结果表明，MAF可以作为未来的增强材料，开发具有潜在应用价值的绿色复合材料.
