silk is no longer used for making parachutes. It was a good material before nylon came along, but no parachutes are made from silk anymore. Not for decades.

When it WAS used, it was because it was very light, extremely strong, was not bulky, and could be woven in a very tight weave.
it is durable and the material is somewhat cost-effective.
nylon threads
The material properties are suitable for the purpose,(color, shape, corrosion resistant....) and they're cheap to make.
I'm not sure. Just as long as they aren't Jewish I'll be able to sleep tonight...
I think that they currently use nylon, but they used to use silk
In 1941 right when pearl harbor happended. They used the material nylon to make these parachutes during the great depression also.
The answer depends on what its "job" is.
non reactive
It will have different properties.
By combining the best properties of each material.
because the other material is not suitable
The properties of a material are its characteristics, the things you would tell about if you were describing the material to someone else, the things that make it different from other materials, and the things about it that tell you what material it is when you see, feel, or smell it.
