Chain matrix

Bullet proof chainmail

Bullet proof material requires the momentum of bullet to be completely transferred/absorbed to the material in the shortest possible distance. A typical bullet proof material has an amount of ‘give’, allowing the bullet to penetrate though some of the material as a way of absorbing the energy.

Chainmail has been tried as a bullet proof material, but the results were unsatisfactory because the rings would fragment. This is probably because the rings in chainmail don’t have enough ‘give’. So I’ve added some ‘give’ to chainmail and made it 3 dimensional to increase the bullet stopping distance.

The (brass coloured) rings are connected with (off-pink colour) rubber bands as shown in linked pictures (chainmail_3d_suspension 1 and 2).

The chain matrix could be used as an interior lining to military vehicles, or as a semi-transparent mesh to cover windows.

       So, do some market research and report back.

       Exellent idea, truly excellent. A very simple idea, with a high probability of actually working. I guess that extensive testing may be required to refine and prove the effectivness of this product, but that is beyond the scope of the half-bakery. [+]

       Incorporate *lots* of impact resistant rubber gel threads into the chainmail and the projectiles could ricochet off in different directions.

       no chance of the bullet going in dragging the mail with it? happened alot in medieval time causing all sorts of mischief.

       just for the idea of making chain mail rings in a 3d matrix, i voted for this idea but i think metal would be too heavy   

       there is a controversial armor called dragon skin that updated another old armor type - scale armor. Instead of scales of steel, it uses larger discs of composite/ceramic material over kevlar. much more flexible and much more coverage than the old level 4 bulletproof vests who use a big slab of ceramic/composite called a trauma plate (they copied plate armor).
