Abstract

Eco-friendly materials receive more attention due to the necessity of addressing pollution and resource depletion in the face of exponential industrial expansion. Natural fibers provide a sustainable substitution, especially in green composites. This study investigated the feasibility of Allium fistulosum L. (Scallion) as a fiber resource for composite applications by using its tassel. Allium fistulosum L. is derived from a widely available plant and its waste tassels of the plant provide fiber properties and have the potential to be a reinforcing component in composites. The investigation involves characterizing Allium fistulosum L. (AfL) fibers through various analyses. The density of the AfL was determined approximately 1.35 – 1.45 g/ cm3. The percentages of lignin, hemicellulose, and cellulose were found to be 24.31%, 29.73%, and 38.36%, respectively. FTIR and XRD analysis affirm AfL's cellulose, hemicellulose, and lignin presence. SEM images indicate a rough surface, necessitating modification for better matrix compatibility. TGA shows suitable thermal stability, majorly degrading beyond 267°C. Tensile testing demonstrates a tensile strength of 22.19 ±3.75 MPa and 0.87 ±0.16 GPa modulus, exceeding some natural fibers like aerial banyan tree roots and Cordia dichotoma. Results show promising features, indicating the viability of AfL fibers in composites with reduced environmental impact and economic benefits.
大葱新茎秆和新茎秆制造技术研究与分析
由于工业急剧扩张,必须解决污染和资源枯竭问题,生态友好型材料受到越来越多的关注。天然纤维提供了一种可持续的替代品,尤其是在绿色复合材料中。本研究利用薤白(Scallion)的穗作为复合材料应用的纤维资源,对其可行性进行了调查。Allium fistulosum L.是从一种广泛存在的植物中提取的,其废弃的植物穗具有纤维特性,有潜力成为复合材料中的增强成分。这项研究通过各种分析来确定 Allium fistulosum L. (AfL) 纤维的特性。经测定,AFL 的密度约为 1.35 - 1.45 克/立方厘米。木质素、半纤维素和纤维素的百分比分别为 24.31%、29.73% 和 38.36%。傅立叶变换红外光谱和 XRD 分析证实了 AfL 中纤维素、半纤维素和木质素的存在。扫描电子显微镜(SEM)图像显示其表面粗糙,有必要对其进行改性,以获得更好的基质兼容性。TGA 显示了适当的热稳定性,主要在 267°C 以上降解。拉伸测试表明,其拉伸强度为 22.19 ±3.75 兆帕,模量为 0.87 ±0.16 GPa,超过了一些天然纤维,如气生榕树根和帘子草。结果表明,Afl纤维在复合材料中的应用前景广阔,可减少对环境的影响并带来经济效益。
