Abstract

The composite industry is focusing on bio-waste as an alternative source of raw materials to address sustainability challenges in its procedures and goods. This study describes the characteristics of Licuala grandis tree peduncle fibers (LGPFs), a novel agro-waste that is segregated from the peduncle of the tree. Quantifiable information about LGPF, such as its tensile strength (232–273 MPa), Young’s modulus (2.2–4.9 GPa), better crystallinity index (51%), and cellulose proportion (58.31 weight percent), is obtained owing to the thorough examination. Thermogravimetric (TGA/DTG) and differential scanning calorimetry (DSC) inquiries provide insight into the LGPF’s thermal behavior and reveal that it will remain stable up to 236 °C. The analysis of Fourier transform infrared spectroscopy (FTIR) spectroscopy helps to validate the outcomes of chemical examination. Scanning electron microscope (SEM) analysis of the LGPF’s surface roughness supported the idea of using it as reinforcement material in composites with polymer as matrix. LGPF-reinforced polymer composites can be used in structural applications, according to the experimental findings.

评估用于轻质生物复合材料的新型纤维素生物纤维的机械、热和形态特性

复合材料行业正专注于将生物废料作为替代原料来源，以应对其生产程序和产品的可持续性挑战。本研究描述了一种新型农业废弃物--大叶女贞（Licuala grandis）树干纤维（LGPFs）的特性，这种纤维是从树干中分离出来的。通过对 LGPF 进行彻底检查，获得了有关其拉伸强度（232-273 兆帕）、杨氏模量（2.2-4.9 GPa）、较好的结晶度指数（51%）和纤维素比例（58.31 重量百分比）等可量化信息。热重法（TGA/DTG）和差示扫描量热法（DSC）研究深入了解了 LGPF 的热行为，发现它在 236 °C 以下仍能保持稳定。傅立叶变换红外光谱（FTIR）分析有助于验证化学检测的结果。对 LGPF 表面粗糙度的扫描电子显微镜（SEM）分析支持了在以聚合物为基体的复合材料中使用 LGPF 作为增强材料的想法。实验结果表明，LGPF 增强聚合物复合材料可用于结构应用。
