Hi Pennies,

Thanks for sending this info.

The issue with Entogenics is they could never get the spider silk protein integrated into the structure of the silk. They successfully were able to produce the proteins in small amounts within the silkworms. So their silk never had any significant mechanical properties over regular silkworm silk.

Also, you can make almost any material bulletproof if you make it thick enough. In fact, Thai police officers have used regular silkworm silk for ballistics protection for years. It just takes a lot of layers. My guess is Entogenetics made thick shootpacks that performed the same as normal silkworm silk would. Just a guess on my though.

A critical value in the performance of shoot packs is the speed of sound through the material. The faster the speed of sound, the more surface of the material will absorb the shock, leading to a wide backface signature with little depth. A slower speed of sound means that less of the material will absorb the impact, thus creating a more narrow and deep impression.

Thank you for this. I didn't know this was a variable. Yet another piece of evidence showing the necessity to test these instead of saying "it's too flexible for a bulletproof vest"
