(Spider dragline silk has a tensile strength of roughly 1.3 GPa. The tensile strength listed for steel might be slightly higher – e.g. 1.65 GPa, [24] [25] but spider silk is a much less dense material, so that a given weight of spider silk is five times as strong as the same weight of steel.)
The spider silk has a greater tensile strength than steel, and the material is even strong enough to stop a bullet. In terms of everyday usage, spider silk could be a huge game changer when it ...
The different types of silk (major ampullate silk, minor ampullate silk, flagelliform silk, aciniform silk, tubiliform silk, pyriform silk, and aggregate silk) [11] are composed of different types of proteins. Dragline silk is mainly formed by spidroin proteins. It is a type of major ampullate silk and is produced in the major ampullate gland.
Dragon silk combines the elasticity and strength of spider silk. It has the tensile strength as high as 1.79 gigapascals (as much as 37%) and the elasticity above 38% exceeding the maximum reported features of the spider silk. [citation needed] It is reported that dragon silk is more flexible than the "Monster Silk" and stronger than the "Big ...
The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009. [4] Its silk is the toughest biological material ever studied. Its tensile strength is 1.6 GPa. [5] The species was named in honour of the naturalist Charles Darwin on November 24, 2009—precisely 150 years after the publication of The Origin of Species. [2]
The ultimate tensile strength and other physical properties of Latrodectus hesperus (western black widow) silk are similar to the properties of silk from orb-weaving spiders that had been tested in other studies. The tensile strength for the three kinds of silk measured in the Blackledge study was about 1,000 MPa.

BioSteel was a trademark name for a high-strength fiber-based material made of the recombinant spider silk-like protein extracted from the milk of transgenic goats, made by defunct Montreal-based company Nexia Biotechnologies, and later by the Randy Lewis lab of the University of Wyoming and Utah State University.
