ABSTRACT

Recently, bio-based composites are the prominent material to replace several synthetic fiber-based composites because of their abundant availability, ecological, biodegradable, and sustainable properties. This study aims to examine the use of new natural fibers, which were extracted from the Momordica charantia plant stem as reinforcement in polymer composites. The results showed that the Momordica charantia fibers had cellulose content (61.2 %), density (1339 ± 6.4 kg/m³), fiber diameter (198 ± 3.9 µm). The thermal studies using thermogravimetric analysis revealed the degradation temperature as 339.1°C with a char residue of 21% at 600°C. The results of this work confirmed that the properties of the Momordica charantia plant stem fibers are suitable materials as a reinforcement for the development of the biocomposite for potential applications.

摘要

最近，生物基复合材料因其丰富的可用性、生态、可生物降解和可持续的特性而成为替代几种合成纤维基复合材料的重要材料。本研究旨在检验从苦瓜植物茎中提取的新型天然纤维作为聚合物复合材料中的增强材料的用途。结果表明，苦瓜纤维的纤维素含量（ 61.2%）、密度（1339±6.4 kg/m ³）、纤维直径（198±3.9 µm）。使用热重分析进行的热研究表明，降解温度为 339.1°C，在 600°C 时有 21% 的焦炭残留物。这项工作的结果证实了苦瓜的特性植物茎纤维是合适的材料，可作为用于开发潜在应用的生物复合材料的增强材料。
