植物纤维具有低能量生产成本、可生物降解性和良好的力学性能等优点，在复合材料增强材料领域具有很大的应用前景。本研究的目的是比较两种环保水洗对亚麻纤维（Electra品种）热行为、表面形态和力学性能的影响。作为第一步，我们进行了扫描电子显微镜（SEM）来评估表面性能，并进行了热重分析（TGA）来评估处理对纤维成分的影响。其次，对初等纤维进行拉伸试验。结果表明，水处理对初等纤维的力学性能没有负面影响。此外，在23℃下水洗72 h后，杨氏模量值略有增加，这可能是由于亚麻纤维的表面状态更好，更容易提取。最后，对洗脱糖的分析表明，煮沸处理对纤维结构有一定的负面影响。(C) 2010 Elsevier B.V.版权所有
Plant fibers have several aspects, such as low energetic production costs, biodegradability and great mechanical properties, which make them very attractive in the field of composite reinforcement. The aim of this study was to compare the impact of two eco friendly water washings on the thermal behavior, surface morphology and mechanical properties of flax fibers (Electra variety).As a first step, we have carried out scanning electronic microscopy (SEM) to evaluate surface properties and performed thermogravimetric analysis (TGA) to estimate the effects of the treatments on the fiber composition. Secondly, tensile tests were performed on elementary fibers. The results show no negative impact of water treatment on the mechanical properties of the elementary fibers. Moreover, after water washing for 72 h at 23 degrees C. the Young's modulus values appeared to increase slightly, possibly due to better surface state and an easier extraction of flax fibers. Finally, an analysis of eluted sugars suggests some negative effect of the boiling treatment on the fiber structure. (C) 2010 Elsevier B.V. All rights reserved.
