Abstract

Natural fibers are eco-friendly, biodegradable materials derived from plants, animals, or minerals, offering sustainability, comfort, and reduced environmental impact compared to synthetic fibers. This study focuses on developing and dynamic mechanical characterization of epoxy composites reinforced with 5 % alkali-processed Areca leaf sheath fibers (15 mm length, 30 % fiber volume). The composites were evaluated for drop weight impact resistance, natural frequency, and damping. The optimized composition exhibited superior dynamic properties, with fundamental frequencies ranging from 15.82 to 909.33 Hz (modes 1–5), and impact energies of 1.735 J and 2.2 J at drop heights of 250 mm and 500 mm, respectively. SEM analysis confirmed improved fiber–matrix interfacial bonding. These findings highlight the potential of Areca fiber composites as sustainable alternatives to plywood for lightweight, vibration-sensitive applications.

槟榔叶鞘纤维在高分子复合材料开发中的应用：动态分析

天然纤维是从植物、动物或矿物中提取的生态友好、可生物降解的材料，与合成纤维相比，它提供了可持续性、舒适性，并减少了对环境的影响。研究了5%碱处理槟榔叶皮纤维（长度为15mm，纤维体积为30%）增强环氧复合材料的动态力学性能。对复合材料进行了落锤抗冲击性、固有频率和阻尼的评估。优化后的复合材料具有优异的动态性能，基频范围为15.82 ~ 909.33 Hz（模态1 ~ 5），跌落高度为250 mm和500 mm时的冲击能分别为1.735 J和2.2 J。SEM分析证实纤维-基体界面结合得到改善。这些发现突出了槟榔纤维复合材料作为轻质、振动敏感应用中胶合板的可持续替代品的潜力。
