2. Spider Silk 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.
This fiber is ultra light, about 25% lighter then traditional polymers.
3. Spider Silk Cont. elastic modulus 10-50 GigaPascals, and has tensile strength of 1.1-1.4 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.
4. Problems with Spider Silk 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 has cloned a goat with spider genes.
5. Webster and Pete 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.
The silk milk from the goats will then be used to create fibers known as Biosteel.
