Spider silk is a protein fiber spun by spiders, which they use to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators.
Each spider and each type of silk has a set of mechanical properties optimized for their biological function, but in particular, their dragline silks, have exceptional mechanical properties. They exhibit a unique combination of high tensile strength and extensibility which enables a silk fiber to absorb a large amount of energy before breaking with this estimated tensile strength several times that of steel.
