Abstract

The objective of this study was to investigate tensile properties of two grape cane fibers, namely, outer bark (OB) and inner bark (IB). The cane is a necessary annual by-product from vineyards and is produced at approximately 36 million tons yearly around the world, which currently has no substantial commercial utilization. Grape cane fibers were subjected to an alkali treatment, at different concentrations, to separate the fibers from the cane. Moreover, two displacement methods such as system compliance ( C s ) and digital image correlation (DIC) were performed to determine Young’s modulus of the samples, and the results were compared. The OB fibers had better overall properties than IB fibers. The effect of the treatment concentrations (1, 3, 5, and 7 wt% of sodium hydroxide) and gage lengths (10, 25, and 40 mm) on the tensile properties was not consistent for both fiber types. The DIC method consistently yielded greater tensile modulus of the samples than the  C s  method for OB fibers.
利用积分数字图像相关法研究碱处理对葡萄甘蔗纤维拉伸性能的影响
本研究的目的是研究两种葡萄甘蔗纤维,即外皮(OB)和内皮(IB)的拉伸性能。甘蔗是葡萄园的一种必要的年度副产品,全世界每年生产约3600万吨,目前没有大量的商业利用。对葡萄藤纤维进行不同浓度的碱处理,使其与甘蔗分离。采用系统柔度(C s)和数字图像相关(DIC)两种位移法测定试样的杨氏模量,并对结果进行比较。OB纤维的综合性能优于IB纤维。处理浓度(1、3、5和7 wt%的氢氧化钠)和规格长度(10、25和40 mm)对拉伸性能的影响在两种纤维类型中并不一致。对于OB纤维,DIC方法始终比C - s方法获得更大的拉伸模量。
