Date palm rachis fibers are rich in cellulose, relatively inexpensive, and readily available in Algeria. The aim of this study is to investigate the morphology, structure, mechanical and physicochemical characteristics of both vascular bundles and fiber strands extracted from date palm rachis. The difficulties encountered are associated to the extraction of the fibers without damaging them. The study focuses on the morphological and surface roughness analysis using optical and scanning electron microscopies (SEM), and a non-contact 3D profiler. The chemical, physical and thermal properties have been studied using Fourier-transform infrared (FTIR) spectroscopy, energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The mechanical properties were accessed by tensile tests and they were analyzed using two-parameter Weibull distribution.
椰枣叶柄纤维富含纤维素，价格相对较低，在阿尔及利亚也很容易获得。本研究旨在研究从椰枣叶柄中提取的维管束和纤维束的形态、结构、力学和物理化学特性。所遇到的困难与纤维的提取有关，需要在不损坏纤维的情况下进行提取。研究集中在使用光学显微镜和扫描电子显微镜（SEM）以及非接触式 3D 轮廓仪对形态和表面粗糙度进行分析。利用傅里叶变换红外（FTIR）光谱、能谱（EDX）、X 射线衍射（XRD）、热重分析（TGA）和差示扫描量热法（DSC）研究了化学、物理和热性能。通过拉伸试验评估了力学性能，并使用双参数 Weibull 分布进行了分析。
