This article has been prepared by MT editorial staff, based on a variety of open sources to provide a general review of the key technologies associated with the design and manufacture of body armour. What is normally referred to as soft body armour works by catching the bullet in a net-like web of very strong fibres. The bullet stretches not only the few fibres it hits, but also others in contact with them and many more that those pull. As in any net, the key to success is that many fibres, even those not actually touching the bullet, elongate in response to the collision and so absorb the energy of the bullet.
