Abstract

The increasing concern for the environment has driven a surge in popularity of utilizing modern technology to develop new products from renewable resources. To address this, polymer composites are incorporating various bio-waste materials as filler components. This study focuses on fabricating four-layered hybrid polyester laminates using kenaf (K), glass (G), and reinforced with fish scale (FS) powder at concentrations ranging from 5 wt.% to 15 wt.%. Mechanical properties are assessed following ASTM standards to evaluate the optimal FS filler percentage. The results reflect that the KGKG laminate with 15 wt. % FS exhibits utmost tensile strength and hardness, while the same laminate with 10 wt. % FS shows optimal flexural and impact properties. Further, numerical analysis is performed using ANSYS 19.0 software to validate the experimental findings. It is marked that, the results of numerical analysis are align intimately with the experimental data, with a deviation of 5 to 10%. Additionally, the moisture absorption behavior is investigated, and the results revealing that FS filler reduced moisture uptake and enhanced dimensional stability. Further, the study is extended to investigate the thermal attributes of laminates through Thermogravimetric Analysis (TGA) and Dynamic Mechanical Analysis (DMA). The fractured surface morphology are studied through Scanning Electron Microscopic (SEM) and the findings reveal significant occurrences of matrix cracking, fiber withdrawal, and the separation of fibers from the matrix. Overall, this study suggests the incorporation of FS bio-fillers into hybridized kenaf/glass laminates in order to improve performance and create environmentally friendly options that suitable for automotive applications.

鱼鳞粉添加量和堆叠顺序对混合槿麻/玻璃聚酯复合材料机械和热性能的影响
随着人们对环境的日益关注,利用现代技术从可再生资源中开发新产品的做法越来越受欢迎。为解决这一问题,聚合物复合材料中加入了各种生物废料作为填充成分。本研究的重点是使用槿麻 (K)、玻璃 (G) 和鱼鳞粉 (FS) 制造四层混合聚酯层压板,鱼鳞粉的浓度从 5 wt.% 到 15 wt.% 不等。根据 ASTM 标准对机械性能进行了评估,以确定最佳的 FS 填料比例。结果表明,含有 15 重量百分比 FS 的 KGKG 层压板具有最佳的拉伸强度和硬度,而含有 10 重量百分比 FS 的同一层压板则具有最佳的弯曲和冲击性能。此外,还使用 ANSYS 19.0 软件进行了数值分析,以验证实验结果。结果表明,数值分析的结果与实验数据基本一致,偏差在 5%到 10%之间。此外,还对吸湿行为进行了研究,结果表明 FS 填料降低了吸湿性并增强了尺寸稳定性。此外,研究还通过热重分析(TGA)和动态机械分析(DMA)对层压板的热属性进行了扩展。通过扫描电子显微镜(SEM)对断裂表面形态进行了研究,结果发现基体开裂、纤维抽出和纤维与基体分离等现象明显。总之,这项研究建议将 FS 生物填料加入杂化的槿麻/玻璃层压板中,以提高性能并创造适合汽车应用的环保型选择。
