Spider silk fibers are of scientific and industrial interest because of their extraordinary mechanical properties. These properties are normally determined by tensile tests, but the values obtained are dependent on the morphology of the fibers, the test conditions, and the methods by which stress and strain are calculated. Because of this, results from many studies are not directly comparable, which has led to widespread misconceptions in the field. Here, we critically review most of the reports from the past 50 years on spider silk mechanical performance and use artificial spider silk and native silks as models to highlight the effect that different experimental setups have on the fibers' mechanical properties. The results clearly illustrate the importance of carefully evaluating the tensile test methods when comparing the results from different studies. Finally, we suggest a protocol for how to perform tensile tests on silk and biobased fibers.
蜘蛛丝纤维因其非凡的机械性能而具有科学和工业价值。这些性能通常通过拉伸试验来测定，但所获得的值取决于纤维的形态、测试条件以及应力和应变的计算方法。因此，许多研究的结果无法直接比较，这导致了该领域广泛的误解。在此，我们批判性地回顾了过去50年中关于蜘蛛丝机械性能的大多数报告，并以人工蜘蛛丝和天然丝为模型，以突出不同实验设置对纤维机械性能的影响。结果清楚地表明，在比较不同研究的结果时，仔细评估拉伸试验方法的重要性。最后，我们提出了一个关于如何对丝绸和生物基纤维进行拉伸试验的方案。
