Investigation of Physico Chemical, Mechanical and Thermal Properties of the Albizia Lebbeck Bark Fibers

ABSTRACT

The production of materials using synthetic fibers is a strong contributor to carbon emissions and waste. Because of growing environmental consciousness, natural fibers act as a substitute for synthetic fibers due to their renewable, eco-friendly and bio-degradable nature. Natural cellulose fibers are newly identified from the sources of Albizia Lebbeck fibers (ALF). This study is intended to understand the characteristics of ALF extracted from the bark of the Albizia Lebbeck and its physicochemical properties. The structure of the fibers was analyzed by FT-IR and X-ray diffraction. Cellulose content (72.59 wt.%), density (905 kg/m³), and crystallinity index (52.99%) properties were identified in the AL fibers, and thermal studies using Thermo Gravimetric Analysis and Derivative Thermo Gravimetric analysis revealed that the maximum degradation temperature is 353.37°C with kinetic activation energy of 89 kJ/mol. From the results, it is concluded that the properties of ALFs guaranteed that it could be an alternative material as new reinforcement as green composites in the manufacturing and automobile industries.

摘要

使用合成纤维生产材料是碳排放和废物的主要来源. 由于环保意识的增强，天然纤维以其可再生、环保、可生物降解的特性，成为合成纤维的替代品. 天然纤维素纤维是从白合欢纤维（ALF）的来源中新鉴定出来的. 本研究旨在了解白合欢树皮中提取的ALF的特性及其理化性质. 用红外光谱和X射线衍射分析了纤维的结构. 在铝纤维中测定了纤维素含量（72.59重量%）、密度（905公斤/立方米）和结晶度指数（52.99%），热重分析和导数热重分析表明，最大降解温度为353.37℃，活化能为89 mol／mol. 结果表明，ALFS的性能保证了其作为新型增强材料在制造业和汽车工业中的应用.
