Mechanical and Thermal Properties of Nanoclay-Treated Banana Fibers

ABSTRACT

The objective of this work is to improve the thermal, mechanical and fiber-matrix adhesion properties of banana fibers using nanoclay particle infusion. The nanoclays were infused into the banana fibers by using alkaline and silane chemical treatments. The morphology and distribution of nanoclays in banana fiber was examined by scanning electron microscopy. Nanoclay infused fiber resulted in 35.7% and 12.5% increased tensile modulus and strength over untreated fiber, respectively. Thermogravimetric analysis of nanoclay infused banana fiber shows ~ 2.2 times increased weight gain at 600°C when compared with untreated banana fiber.

摘要

本研究旨在通过渗入纳米粘土颗粒提高香蕉纤维的热性能、机械性能和纤维基质粘附性能。在研究中，通过使用碱性和硅烷化学处理将纳米粘土渗入香蕉纤维中，并通过扫描电子显微镜检查纳米粘土在香蕉纤维中的形态和分布。结果显示，与未经处理的纤维相比，纳米粘土纤维使拉伸模量和强度分别提高了35.7%和12.5%。热重分析显示，与未经处理的香蕉纤维相比，经过纳米粘土浸渍的香蕉纤维在600℃条件下重量增加了约2.2倍。
