Spider Silk from Goats By: Dhwani Patel MEEN 3344

Spider Silk Spider silk is extremely strong. It is has tensile strength greater then steel and is more flexible. Spider silk is extremely strong. It is has tensile strength greater then steel and is more flexible. A 747 Boeing jet could be stopped in flight by a strand that is pencil thick. A 747 Boeing jet could be stopped in flight by a strand that is pencil thick. This fiber is ultra light, about 25% lighter then traditional polymers. This fiber is ultra light, about 25% lighter then traditional polymers.

Spider Silk Cont. elastic modulus GigaPascals, and has tensile strength of GPa elastic modulus GigaPascals, and has tensile strength of GPa The silk is safe to be used to replace humans body parts giving the user wider range in motion then the traditional replacements available today. The silk is safe to be used to replace humans body parts giving the user wider range in motion then the traditional replacements available today.

Problems with Spider Silk It is extremely difficult to create Spider Silk on a commercial scale It is extremely difficult to create Spider Silk on a commercial scale Nexia, a Canadian company is hoping to create an unlimited supply of Spider Silk in goat milk. Nexia, a Canadian company is hoping to create an unlimited supply of Spider Silk in goat milk. Nexia has cloned a goat with spider genes. Nexia has cloned a goat with spider genes.

Webster and Pete Webster and Pete are the first goats who have this gene. Webster and Pete are the first goats who have this gene. When they mate their kids are hoped to produce milk which has the silk protein. When they mate their kids are hoped to produce milk which has the silk protein. The “silk milk” from the goats will then be used to create fibers known as Biosteel. The “silk milk” from the goats will then be used to create fibers known as Biosteel.
