The spider's silk is the toughest biological material ever studied, over ten times tougher than a similarly-sized piece of Kevlar. The average toughness of the fibres is 350 MJ/m3, and some are up to 520 MJ/m3 , making the silk twice as tough as any other spider silk known.

To find out how most spider silk is five times stronger than steel, scientists analyzed the silk that venomous brown recluse spiders use to create their ground 

Is spider silk stronger than Kevlar? Kevlar is a military grade material which is used in the production of bullet proof vests. The silk of an average spider has a tensile strength of 1.1GPa whilst Kevlar’s tensile strength is 3.0GPa. That being said,

A new fiber, made by genetically engineered bacteria is stronger than steel and tougher than Kevlar. Spider silk is said to be one of the 

Is spider silk stronger than Kevlar? A new fiber, made by genetically engineered bacteria is stronger than steel and tougher than Kevlar. Spider silk is said to be one of the strongest, toughest materials on the Earth. Now engineers at Washington University in St. Louis have designed amyloid silk hybrid proteins and produced them in engineered

Quantitatively, spider silk is five times stronger than steel of the same diameter. It has been suggested that a Boeing 747 could be stopped in flight by a single pencil-width strand and spider silk is almost as strong as Kevlar, the toughest man-made polymer.

However, it seems that researchers could have made something even better. Engineers at the Washington University in St. Louis have developed artificial spider silk that is said to be stronger than steel and even tougher than Kevlar, and in some cases, might actually be tougher than some naturally-produced spider silks.

Spider silk is said to be one of the strongest, toughest materials on the Earth. Now engineers at Washington University in St. Louis have designed amyloid silk hybrid proteins and produced them in engineered bacteria. The resulting fibers are stronger and tougher than some natural spider silks. Their research was published in the journal ACS Nano.

It can be stretched up even to 40% of its original length! Considering the tensile strength, the spider silk strings are much more stronger than steel strings and tougher than the Kevlar. This

Scientists are figuring out the chemical triggers that turn the liquid stored in silk glands into a solid that's tougher than Kevlar. Read more at The New York
