The chief source of strength is the loops the spider spins into each strand. The spinneret produces about 500 microloops per inch of silk. Materials scientists have long known that

In combining these two properties, silks reveal a toughness that is two to three times that of synthetic fibers like Nylon or Kevlar. Spider silk is also 

Though Kevlar is a polyaramid fiber whereas spider silk is a polypeptide fiber, the molecular structures of Kevlar and spider silk are quite 

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 

It's between three and eight microns in diameter but five to ten times stronger than steel or Kevlar: spider silk is an exceptional material.

Darwin's bark spider, however, takes tensile strength an entirely new level. Its dragline silk – the type that forms the energy-absor  

A bullet can penetrate up to 29 layers of Kevlar. But research shows spider silk to be comparatively tougher than Kevlar and stronger than steel 

Though Kevlar is a polyaramid fiber whereas spider silk is a polypeptide fiber, the molecular structures of Kevlar and spider silk are quite similar as seen 

When you think of materials like steel or Kevlar, you get this impression that they are tough, durable, and strong. After all, Kevlar is 

Answer 2: Spiders make their own silk. How many webs can a spider make in a day? They will build their web at night and tear it down during the day and will rebuild a torn web- so at this point about 27 webs. Males wander to find the and seldom make a web. Hope this helps! (Edited to add literature citation.) Can Spider Silk stop a bullet?

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
