摘要
对4种常见蜘蛛大腹园蛛Araneus ventricosus、迷宫漏斗蛛Agelena labyrinthica、草间钻头蛛Hylyphantes graminicola和棒络新妇Nephila clavata蛛丝的物理特性和机械性能进行了初步研究。结果表明:捕丝是由2根核心丝构成,4种蛛丝呈现不同的颜色;4种蜘蛛蛛丝的密度略有不同,棒络新妇的蛛丝密度最大,草间钻头蛛的蛛丝密度最小;蛛丝中棒络新妇的断裂伸长率和断裂强度都最大,分别为47.3%和852.6 Nmm-2,草间钻头蛛蛛丝的断裂伸长率和断裂强度都最小,分别为32.1%和652.3 Nmm-2。与其它物理化学材料相比,蛛丝具有优异的综合力学性能,生物学特性与生物学功能具有高度一致性。
The physical characteristics and mechanical properties of four species spiders＇ silk, which are Araneus ventricosus, Agelena labyrinthica, Hylyphantes graminicola and Nephila clavata, had been studied. The result showed that catching silk is constituted by two core silk, four species spiders＇ silk had different color; The densities of spider＇s silk had slightly dissimilarity. The Nephila clavata＇s silk density is the highest, Hylyphantes graminicola＇s is the lowest. While the tensile strength and extension percentage of Nephila clavata＇s silk are the biggest, and up to 47.3% and 852.6 Nmm-2. Hylyphantes graminicola＇s are the smallest, and up to 32. 1% and the 652. 3 Nmm-2. Compared with other physical and chemical materials, not only the silk had excellent mechanical properties, but the biology characteristic had high consistency with the biology function.
