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.

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

7/21 · The engineered 'spider silk' has a tensile strength higher than common steel and is tougher than Kevlar In , Zhang's team created a recombinant fiber on par with spider silk. Now, they say

Researchers develop fake spider silk that's stronger than steel and tougher than Kevlar by cutting silk-producing genes into bacteria.

Offensive Its synthetic composition is five times stronger than steel and extremely heat resistant to provide protection between 200-400 degrees Fahrenheit Kevlar fiber reinforced more than twice, ordinary bullets could not penetrate Spider silk is

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.

The next step is to see just how strong this silk is. Using a machine that measures how much pulling the thread can take before it snaps, Lewis says his strand of man-made spider silk is stronger

Spider silk fibers have a strength rating of 1.1 gigapascals, which is not as strong as Kevlar's 3.6 gigapascals. But, they are tougher than 

Engineers at Washington University in St. Louis have produced amyloid silk hybrid proteins and turned them into fibres that are stronger and 

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