ABSTRACT

The present investigation aimed to understand the physicochemical properties of new natural fiber extracted from Albizia amara (AA) bark. The chemical composition and structural, thermal, and tensile properties of AA fibers (AAFs) were investigated. The results indicated that AAF had crystallinity index of 63.78%, cellulose of 64.54 wt%, hemicellulose of 14.32 wt%, lignin of 15.61 wt%, and low density of 1043 kg/m3. Thermogravimetric analysis shows that AAFs were thermally stable up to 330.6°C and the functional groups of the AAFs were identified by Fourier transform infrared analysis. The AAFs exhibited tensile strength of 640 ± 13.4 MPa with strain rate of 1.57 ± 0.04%. This investigation reveals that AAFs could be a suitable material as reinforce agent in natural fiber–polymer composites for different applications.

摘要

本研究旨在了解从albiziaamara树皮中提取的新型天然纤维的理化性质。的化学成分、结构、热性能和力学albiziaamara纤维(AAFS)的影响。结果表明,AAF有结晶度(63.78%)、纤维素(64.54wt%)、半纤维素(14.32wt。%)、木质素(15.61重量%),低密度(1043kg/m3)。热重分析表明和热稳定的高达330.6°C和AAFs的官能团识别fi由傅里叶变换红外分析。展出的640±和13.4 MPa,1.57±0.04%应变率拉伸强度。 本次调查显示,和可能是一个合适的材料作为增强不同应用天然纤维聚合物复合材料代理。
