Spiders are able to produce different types of silk with different mechanical and biological properties. Piriform silk is produced to secure spiders and their webs to surfaces by using a nano-fibril network embedded in a cement-like matrix. Despite their fundamental role, the mechanical properties and function of these anchorages are still poorly understood due to the practical difficulties in nano-fibril sample preparation, the complexity of the system, and the high variation of attachment disc structures. Here we estimated the mechanical properties of this nano-fibril silk and those of the whole silk membrane in the large wandering spider

强韧的丝绸用于弹性附着盘:蜘蛛Cupiennius salei中的梨状丝绸的机械特性(Keyserling,1877年)
蜘蛛能够生产具有不同机械和生物学特性的不同类型的丝绸。通过使用嵌入在水泥样基质中的纳米原纤维网络将梨状蜘蛛丝制成,将蜘蛛及其网状物固定在表面上。尽管它们具有基本作用,但由于纳米原纤维样品制备中的实际困难,系统的复杂性以及附着盘结构的高度变化,这些锚固物的机械性能和功能仍知之甚少。在这里,我们估计了这种纳米原纤丝的机械性能以及大型流浪蜘蛛的整个丝膜的机械性能。
