Abstract

The prime objective of the present work has been to investigate a novel natural fiber extracted from the seed pods of the Alstonia macrophylla (AM) tree. Chemical, physico-mechanical, and surface properties of untreated and alkali treated AM fibers were analysed. Chemical analysis confirmed that cellulose composition (78.31 wt%) of the AM treated fiber was improved as a result of alkali treatment, whereas other constituents, such as hemicelluloses, lignin and wax were decreased. This was supported by Fourier transform infrared (FTIR) analysis. Single fiber pull test showed that alkali treated AM fiber exhibited higher strength than untreated AM fiber. Scanning electron microscopy (SEM) studies revealed that surface roughness of the treated AM fiber was higher than in untreated AM fiber. Owing to an upsurge in the cellulose content, the tensile properties, crystallinity, and surface roughness of the AM treated fiber got enhanced, demonstrating that AM fiber could be potentially used as reinforcement for producing polymer composites for light weight applications.

从大叶alstonia种子荚中提取的纤维素纤维作为聚合物复合材料的潜在增强材料

本工作的主要目的是研究从Alstonia macrophylla（AM）树种子荚中提取的一种新型天然纤维。分析了未处理和碱处理AM纤维的化学、物理、机械和表面性能。化学分析证实，AM处理的纤维的纤维素组成（78.31wt%）由于碱处理而得到改善，而其他成分，如半纤维素、木质素和蜡减少。傅立叶变换红外光谱（FTIR）分析支持了这一点。单纤维拉伸试验表明，碱处理AM纤维的强度高于未处理AM纤维。扫描电子显微镜（SEM）研究表明，处理后的AM纤维的表面粗糙度高于未处理的AM纤维。由于纤维素含量的激增，AM处理纤维的拉伸性能、结晶度和表面粗糙度都得到了提高，这表明AM纤维有可能作为增强材料用于生产轻质聚合物复合材料。
