Is Spider Silk Stronger Than Steel? - MythBusters Jr.

Spider silk is incredibly tough and is stronger by weight than steel. Quantitatively, spider silk is five times stronger than steel of the same diameter. It has been.

The spider silk that's five times stronger than steel

You must have heard that spider silk is stronger than steel. We all want to believe that there are wonder materials in nature that are far superior to human-made ones. But the problem with statements that sound too good to be true is that they usually are. Spider silk is not stronger than steel. But that shouldn't stop us from studying it, or from thinking of it as a wonder material. At best, spider silk might compare to steel when it comes to tensile strength, which is the largest stress that a material can withstand before breaking.

silk's tensile strength is comparable to that of high-grade alloy steel times greater and with higher tensile strength than spider silk.

We have almost reached our second goal of funding a toughness study! Just need a couple more supporters. I always accepted this as fact. It is exciting to analyze naturally-occurring materials to see if we can learn to make our current materials better. Spider silk is not stronger than steel. In a review of studies on spider silk properties the strongest reported value was MPa ultimate tensile strength [1].

Spider silk. Thinner than a human hair, but handles loads hundreds of times its size. It can be woven into elaborate structures by minute arthropods. Legions of chemists, material scientists, and engineers study and try to mimic silken threads that spiders create, dismantle, and re-create every day to trap prey. A wonder of the creature world for over million years, natural silk is produced by invertebrate animals in the phylum Arthropoda, also known as arthropods. Common silk producers include silkworms, lacewings, and spiders.
