Abstract

Lightweight materials are continuously required for various parts of automobile and aerospace applications. In this connection, natural fibers are widely used to develop polymer composites due to their being biodegradable and lightweight. The demand for natural fiber for developing the lightweight polymer composite is needed for new fibers. The present work extracts and characterizes the bio-fiber from the Pithecellobium dulce (PDs) plant. The Pithecellobium dulce fiber (PDF) has a cellulose content of 63.45 wt.%, hemicellulose content of 14.56 wt.%, lignin content of 8.45 wt.%, wax content of 0.37 wt.%, moisture content of 11.71 wt.%, and ash content of 4.85 wt.%. The physical density and crystallinity index of PDF was 1097 kg/m3 and 9.7 %. The tensile strength and Young’s modulus properties were identified as 317–1608 MPa and 8.41– 69.61 GPa. The thermal stability of PDF showed at higher temperatures of 339.1°C. This revealed higher cellulose content leading to the higher bonding of cellulose structure. The properties of PDFs can be used to make green polymer composites.

新纤维素纤维的提取特性

汽车和航空航天应用的各种部件不断需要轻质材料。在这方面，天然纤维由于其可生物降解和轻质性而被广泛用于开发聚合物复合材料。发展轻量化高分子复合材料需要天然纤维，需要新型纤维。本研究主要从毛竹(picelellobium dulce, PDs)植物中提取生物纤维并对其进行了表征。该纤维纤维素含量为63.45 wt.%，半纤维素含量为14.56 wt.%，木质素含量为8.45 wt.%，蜡含量为0.37 wt.%，水分含量为11.71 wt.%，灰分含量为4.85 wt.%。PDF的物理密度和结晶度指数分别为1097 kg/m3和9.7%。拉伸强度为317 ~ 1608 MPa，杨氏模量为8.41 ~ 69.61 GPa。PDF在339.1℃高温下表现出热稳定性。这表明较高的纤维素含量导致较高的纤维素结构结合。pdf的特性可用于制造绿色高分子复合材料。
