Lignocellulosic fiber extracted from saltbush (Atriplex halimus L.) is characterized as reinforcement of composite materials. The morphological, physical, thermal and mechanical properties of fibers were addressed for the first time in this paper. The fibers were also subjected to chemical analysis. Stems were boiled in 0.5% sodium hydroxide (NaOH) or 10% sodium bicarbonate (NaHCO₃). Optical and scanning electron microscopy images show an abundance of fiber in the form of thick-walled polygonal tubes. NaOH treatment yielded rough-surfaced fibers whereas the NaHCO₃ treatment yielded smooth-surfaced fiber. Attenuated total reflectance Fourier transform infrared analysis revealed that NaOH treatment removed amorphous components. Based on x-ray diffraction, the crystallinity index increased from 55% to 57%. Thermogravimetry and differential scanning calorimetry showed that the fiber was thermally stable up to 220 °C and 235 °C with activation energies of 56 kJ/mol and 72 kJ/mol respectively for bicarbonate-treated and NaOH-treated material. In single-fiber tensile tests, the latter was stronger, with a Young's modulus of up to 19 GPa and tensile strength of 229 MPa.

从saltbush（Atriplex halimus L.）中提取的木质纤维素纤维的特征是增强了复合材料。本文首次讨论了纤维的形态，物理，热和机械性能。纤维也经过化学分析。将茎在0.5％氢氧化钠（NaOH）或10％碳酸氢钠（NaHCO ₃）中煮沸。光学和扫描电子显微镜图像显示了厚壁多边形管形式的大量纤维。NaOH处理产生的纤维表面粗糙，而NaHCO ₃处理得到表面光滑的纤维。衰减的全反射傅立叶变换红外分析表明，NaOH处理去除了无定形成分。基于x射线衍射，结晶度指数从55％增加到57％。热重法和差示扫描量热法显示，该纤维在碳酸氢根处理和NaOH处理的材料下在高达220°C和235°C的温度下均具有56 kJ / mol和72 kJ / mol的活化能。在单纤维拉伸试验中，后者的强度更高，杨氏模量高达19 GPa，拉伸强度为229 MPa。
