Abstract

Arecanut leaf sheath (ANLS) an unexplored agricultural biomass is used to recover long staple lignocellulosic fibers. A long staple lignocellulosic fiber is extracted from ANLS biomass using 8% NaOH treatment. As reinforcing material ANLS fibre properties such as fibre length, diameter, moisture content, single fibre strength and X-ray diffraction analysis were carried out. Three types of composites, 15, 20 and 25 (w/w)% fibre loading composites have been prepared in unsaturated polyester resin matrix. The tensile, flexural and interlaminar shear strength (ILSS) properties and void content of these composites are studied. The tensile fracture behaviors of fibre and composites are studied with the help of scanning electron micrographs.

摘要

槟榔叶鞘 (ANLS) 是一种未开发的农业生物质，用于回收长纤维木质纤维素纤维。使用 8% NaOH 处理从 ANLS 生物质中提取长纤维木质纤维素。作为增强材料，进行了ANLS纤维特性，例如纤维长度、直径、水分含量、单纤维强度和X射线衍射分析。在不饱和聚酯树脂基体中制备了三种类型的复合材料，15、20 和 25 (w/w)% 纤维负载复合材料。研究了这些复合材料的拉伸、弯曲和层间剪切强度 (ILSS) 性能和空隙率。借助扫描电子显微照片研究了纤维和复合材料的拉伸断裂行为。
