Functionally‐Graded Serrated Fangs Allow Spiders to Mechanically Cut Silk, Carbon and Kevlar Fibers

Functionally‐Graded Serrated Fangs Allow Spiders to Mechanically Cut Silk, Carbon and Kevlar Fibers

Abstract Before humans and allegedly any animal group, spiders developed “functionally graded toothed blades” that cut one of the toughest biological materials: silk. Here, this work reveals the importance of micro‐structured serrations in spiders’ fangs that allow these animals to cut silk and arti...
