Humidity And Rest Period Effects On Viscid Silk Recovery, Catherine Donley
Humidity And Rest Period Effects On Viscid Silk Recovery, Catherine Donley
Williams Honors College, Honors Research Projects
Spider silk applications, and applications of composite materials generally, are limited due to lack of recovery once damaged. Viscid silk, however, is known to have self-healing capabilities which restore, at least partially, its initial properties. If maximized, this ability could potentially increase viscid silk’s practicality and ultimately, provide insight into a self-healing system of use in synthetics. To that end, samples of viscid silk spun by female Larinioides cornutus spiders were tested via cyclical loading at 3 different relative humidities, with 3 different rest period lengths between complete cycles. Data from previously-performed tensile tests conducted at the same 3 humidities …
