This study aims to assess the morphology and properties of fibers extracted from a wild natural plant largely available in Algeria known as Juncus effusus L. (JE). The morphology and diameter of the fiber bundles extracted from the stem of the JE plant were characterized by optical and scanning electron microscopy. The functional groups of the extracted lignocellulosic JE fibers were studied by FTIR, their thermal degradation behavior was investigated by TGA and their crystallinity was determined using X-ray diffraction technique. In addition, mechanical characterization was carried out using tensile tests on the lignocellulosic fiber in order to evaluate their strength, strain at break and Young's modulus. In view of the dispersion in the obtained experimental results, the latter were analyzed using the Weibull statistical laws with two and three parameters.
本研究旨在评估从一种在阿尔及利亚广泛存在的野生天然植物中提取的纤维的形态和性能，这种植物被称为灯心草（Juncus effusus L.）。通过光学显微镜和扫描电子显微镜对从灯心草茎中提取的纤维束的形态和直径进行了表征。利用傅里叶变换红外光谱（FTIR）研究了提取的木质纤维素灯心草纤维的官能团，通过热重分析（TGA）研究了其热降解行为，并用 X 射线衍射技术（XRD）测定了其结晶度。此外，还通过对木质纤维素纤维进行拉伸试验进行了力学特性表征，以评估其强度、断裂伸长率和杨氏模量。鉴于实验结果的分散性，使用具有两个和三个参数的威布尔统计定律对其进行了分析。
