藤家具用单叶省藤藤条顺纹抗拉性能比较DOI: 10.13360/j.issn.1000-8101.2015.03.024 Keywords: 单叶省藤, 藤皮, 藤芯, 藤条, 顺纹抗拉强度, 拉伸弹性模量, 天然藤家具Calamus simplicfoilius, rattan peel, rattan core, rattan strips, axial tensile strength, tensile modulus, natural rattan furniture Abstract: 沿单叶省藤径向由外而内选取5种常用的编织条,进行顺纹拉伸试验及性能比较分析,考察不同径向取材位置对顺纹抗拉性能的影响。结果表明,径向取材位置对藤条的顺纹抗拉强度和弹性模量均具有显著影响。顺纹抗拉强度平均值由大到小依次为:二层扁平藤皮>半圆藤芯>圆藤芯>头层扁平藤皮>扁平藤芯;拉伸弹性模量平均值由大到小依次为:圆藤芯>半圆藤芯>二层扁平藤皮>扁平藤芯>头层扁平藤皮。径向取材位置由外而内对应的藤条顺纹抗拉强度和弹性模量值均呈现先增加后减小的趋势。Five rattan (Calamus simplicfoilius) specimens were selected from different parts of the stem along the radial direction. The influence of location on axial tensile properties was analyzed. The results indicated that the sample location significantly impacted on the axial tensile strength and modulus of elasticity. The sequence of axial tensile strength from the highest to the lowest was flat bast, half??round core, round core, flat epidermis and flat core, while the high??to??low sequence of tensile modulus was round core, half??round core, flat bast, flat core and flat epidermis. Both axial tensile strength and modulus of elasticity were initially increased and then decreased with the sampling position changing from the outer part to the inner part of the stem
