Mechanical Properties of Natural Cellulosic Yucca treculeana L. Fiber for Biocomposites Applications: Statistical Analysis

ABSTRACT

Yucca treculeana L. (YT) is increasingly being considered by researchers worldwide as a replacement option for synthetic fibers such as glass fibers. The objective of this study is to determine the tensile quasi-static room temperature mechanical parameters of YT fibers with gauge lengths (GL) of 10, 20, 30, and 40 mm. A comprehensive tensile test program was conducted on 120 fibers grouped in four series to determine the influence of their variability on the tensile strength, ultimate strain at break and elastic Young’s modulus of the YT fibers. The values of the tensile mechanical properties of YT fibers exhibit a large dispersion of results, which is a characteristic of natural fibers, therefore requiring statistical study. For the purpose of studying this dispersion, some statistical tools such as two- and three-parameter Weibull distribution at 95% CI confidence level and one-way analysis of variance (ANOVA) were used.

摘要

Yucca treculeana L.（YT）越来越多地被世界各地的研究人员视为玻璃纤维等合成纤维的替代品. 本研究的目的是确定标距长度（GL）为10、20、30和40 mm的YT纤维的拉伸准静态室温力学参数. 对分成四个系列的120根纤维进行了综合青贮试验，以确定其变异性对YT纤维的抗拉强度、断裂极限应变和弹性杨氏模量的影响. YT纤维的拉伸力学性能值显示出结果的大分散性，这是天然纤维的一个特征，因此需要进行统计研究. 为了研究这种离散度，使用了一些统计工具，如95%可信区间的二参数和三参数威布尔分布以及方差方差分析的单向分析
