Abstract

Abstract The environmental awareness and sustainable nature of plant-based fibers have forced material researchers and automakers to use natural fibers instead of petroleum-based fibers for various industrial applications. The need for environmentally and biodegradable fibers has created a demand in the transportation industry. In this study, bio castor seed shell (C), glass fiber (G), and SiC (SC) fillers in a constant weight fraction (10 %) were reinforced separately with varying weight fractions (5–25 %) of African teff and snake grass fibers to improve the mechanical properties of the hybrid composites. Both African teff and snake grass fibers were subjected to alkaline treatment to remove amorphous elements such as hemicellulose, lignin, and wax, resulting in high surface roughness. The hybrid composites were fabricated by the compression molding technique and their mechanical properties were characterized as per ASTM standards. The fractured surface of the treated fiber was examined by scanning electron microscopy. From the results, it was found that SC10SG20AT showed maximum mechanical properties compared to C10SG20AT and G10SG20AT due to higher load-bearing capacity of SiC filler. Therefore, SC10SG20AT can be recommended for lightweight applications.
非洲聚四氟乙烯和蛇草纤维增强混杂复合材料力学性能的比较研究——生物蓖麻籽壳/玻璃/SiC填料的影响
植物基纤维的环保意识和可持续性迫使材料研究人员和汽车制造商在各种工业应用中使用天然纤维代替石油基纤维。对环保和可生物降解纤维的需求在运输行业产生了需求。在本研究中,生物蓖麻籽壳(C)、玻璃纤维(G)和SiC (SC)填充剂分别加入不同质量分数(5-25 %)的非洲teff和蛇草纤维,以提高混杂复合材料的力学性能。非洲苔草和蛇草纤维都经过碱性处理,以去除半纤维素、木质素和蜡等无定形元素,从而获得高表面粗糙度。采用压缩成型技术制备了复合材料,并按ASTM标准对其力学性能进行了表征。用扫描电镜观察了处理后纤维的断裂表面。结果表明,SC10SG20AT比C10SG20AT和G10SG20AT表现出最大的力学性能,这是由于SiC填料的承载能力更高。因此,SC10SG20AT可以推荐用于轻量级应用。
