Characterization of Natural Fibers from Cortaderia Selloana Grass (Pampas) as Reinforcement Material for the Production of the Composites

ABSTRACT

Due to environmental problems by the use of synthetic fibers in composite materials, researchers are more concerned with searching for eco-friendly materials. Consequently, the use of reinforcing fibers of natural origin is the best option that promotes the obtaining of materials that do not harm the environment. This paper presents characterization of Cortaderia selloana grass (Pampas) fibers by physical-chemical analysis, FTIR, XRD, thermogravimetric analysis, single fiber tensile test and SEM analysis. Diameter (372.6 µm), density (1261 kg/m³), cellulose content (53.7 wt.%), crystallinity index (22%), tensile strength (20 ± 1.0 MPa), Young’s modulus (8.88 GPa), and thermal stability (320°C) properties were identified in the Cortaderia selloana grass (Pampas) fibers. Overall properties of these fibers showed that it could be an alternative source as reinforcement material for the manufacture of composite materials.

摘要

由于复合材料中合成纤维的使用存在环境问题，研究人员更关注寻找环保材料. 因此，使用天然来源的增强纤维是促进获得不危害环境的材料的最佳选择. 本文通过物理化学分析、FTIR、XRD、热重力分析、单纤维拉伸试验和SEM分析，对皮塔德里亚塞洛纳草（潘帕斯）纤维进行了表征. 直径（372.6 μm）、密度（1261kg/m3）、纤维素含量（53.7 wt.）、结晶度指数（22%）、拉伸强度（20 ± 1.0 MPa）、杨的模量（8.88 GPa）和热稳定性 （320°C） 特性在 Cortaderia selloana 草（潘帕斯）中确定. 这些纤维的整体性能表明，它可以作为复合材料制造增强材料的替代来源.
