Tensile Properties Optimization of Date Palm Leaflets Using Taguchi Method

ABSTRACT

Lignocellulosic fibers from date palm are one of the most available biomasses without significant valorization in the world. This work makes use of an experimental Taguchi design with three factors to determine the optimal conditions of three parameters related to date palm leaflets (gauge length, loading speed and fiber position). The paper also shows an analysis of variance for identifying the parameters that provide a maximization of their tensile properties and obtaining a significant linear model for the manufacturing of natural fibers derived from those date palm components. The results show that the factor that most affects the tensile properties of those leaflets is the gauge length, followed by the fiber within the leaflets position. The best properties were obtained for the top part of the leaflets, 20 mm gauge length and 1 mm/min speed. Moisture tests for date palm leaflets have been also carried out; a drying period of 48 h led to a decrease in water content from 53% to 6%.

摘要

枣椰木质纤维素纤维是世界上最有效的生物材料之一，没有明显的价值. 本研究利用田口实验设计，以三因素来确定枣椰叶的三个相关参数（规格长度、装载速度和纤维位置）的最佳条件. 本文还显示了方差分析，以确定参数，提供最大限度的拉伸性能，并获得一个重要的线性模型，为制造天然纤维从这些枣棕榈组件. 结果表明，影响小叶拉伸性能的主要因素是标距长度，其次是小叶部位的纤维. 小叶顶部、20mm标距长度和1mm/min速度获得最佳性能. 对枣椰小叶也进行了水分测试; 干燥48小时使水分含量从53%下降到6%.
