Abstract
Researchers are actively working on developing a long-term substitute for harmful manmade fibres. Because of their unique qualities that fit diverse applications, natural fibres/fillers are proposed as sustainable reinforcements. Integrating natural fibres, such as Corchorus olitorius particles, into composites provides an environmentally conscious choice for a variety of purposes. This research aims to investigate the influence of silanization, a surface modification technique, on the various characterizations and characteristics of Corchorus olitorius particle-based composites. The characterizations included morphological, mechanical and thermal investigations to assess the influence of silanization on the characteristics of the composite. The contact layup process is applied to create composite samples by reinforcing multiple weight proportions of treated particles (2.5%, 5%, 7.5%, 10% and 12.5%) in epoxy resins. The findings demonstrate that silanization elevates the interfacial connectivity between Corchorus olitorius particles and the resins, which produces upgraded mechanical and thermal attributes. The composite containing 5 wt% particles generated the most significant tensile and flexural strength, with gains of about 45% and 31%, respectively, compared to the epoxy composite. Because of the higher interfacial connections of the molecules, the viscoelastic features of the composites indicated that the 7.5 wt% particle-based composite possesses the greatest storage modulus (2.96 GPa), loss modulus (0.4 GPa) and glass transition temperature (90 °C). This study emphasizes the significance of surface alteration procedures such as silanization for boosting the efficiency and long-term viability of composites containing Corchorus olitorius particles. © 2023 Society of Industrial Chemistry.
硅烷化对用于可持续应用的山茱萸颗粒基复合材料表征的影响
研究人员正在积极开发有害人造纤维的长期替代品。由于天然纤维/填料具有适合各种应用的独特品质,因此被建议用作可持续的增强材料。将天然纤维(如吴茱萸颗粒)整合到复合材料中,可为各种用途提供具有环保意识的选择。本研究旨在探讨硅烷化(一种表面改性技术)对以欧鹅掌楸颗粒为基础的复合材料的各种特性和特征的影响。表征包括形态、机械和热学调查,以评估硅烷化对复合材料特性的影响。通过在环氧树脂中添加多种重量比例的处理过的颗粒(2.5%、5%、7.5%、10% 和 12.5%),采用接触铺层工艺制造复合材料样品。研究结果表明,硅烷化提高了 Corchorus olitorius 颗粒与树脂之间的界面连接性,从而改善了机械和热属性。与环氧树脂复合材料相比,含有 5 wt% 颗粒的复合材料产生的拉伸强度和弯曲强度最为显著,分别提高了约 45% 和 31%。由于分子的界面连接较高,复合材料的粘弹性特征表明,7.5 wt%颗粒基复合材料具有最大的存储模量(2.96 GPa)、损耗模量(0.4 GPa)和玻璃化转变温度(90 °C)。这项研究强调了硅烷化等表面改性过程对于提高含有欧石珊瑚颗粒的复合材料的效率和长期可行性的重要意义。© 2023 工业化学学会。
