Characterization of a Novel Natural Filler from Sirisha Bark

ABSTRACT

Nowadays, the search for natural filler to be substituted for synthetic filler providing renewability, eco-friendly, low cost and nontoxic have prompted the researcher to suggest new natural filler reinforced composite materials for structural and automotive application. The bast fibers like sisal, jute, hemp, ramie and flax have already been studied as reinforcements to the polymer composites with enhanced mechanical, thermal and flammability properties. The present study was intended to examine extensively the characteristics of the novel Sirisha bark filler as an alternate novel filler to the polymer composites. The density of the bark filler was found to be 0.713 g/cc. The cellulose, hemicellulose, lignin, moisture and ash content of the filler were found to be 68.23%, 13.26%, 13.25%, 12.66% and 1.82% respectively in comparison to other bark filler. The crystallinity index was calculated to be 65.71% from the X-Ray Diffraction (XRD) analysis. The Thermogravimetric analysis (TGA) study revealed the thermal stability of the Sirisha bark filler to the temperature of 429°C with activation energy of 54.5 kJ/mol. The trace elements like Ca, Al were found to be 1.30% and 2.54% from Energy-dispersive X-ray spectroscopy (EDX).

摘要

近年来, 寻找天然填料替代合成填料具有可再生性, 环保, 低成本, 无毒等优点, 促使研究者提出了一种新型的天然填料增强复合材料, 用于结构和汽车领域. 麻类纤维如剑麻, 黄麻, 大麻, 苎麻, 亚麻等已被研究作为增强聚合物复合材料的增强体, 具有增强的力学, 热学和燃烧性能. 本研究的目的是广泛研究新型Sirisha树皮填料作为聚合物复合材料的替代新型填料的特性. 树皮填料的密度为0.713g/cc. 与其它树皮填料相比, 其纤维素, 半纤维素, 木质素, 水分和灰分含量分别为68.23%, 13.26%, 13.25%, 12.66%和1.82%. 经X射线衍射 (XRD) 分析, 结晶度指数为65.71%. 热重分析 (TGA) 表明, Sirisha树皮填料在429°C的温度下具有热稳定性, 活化能为54.5kj/mol. 能量色散X射线能谱 (EDX) 分析表明, Ca, Al等微量元素含量分别为1.30%和2.54%.
