Abstract: An armor system useful, for example, as a shroud, comprising a first pliable, cut resistant fibrous layer and a second pliable fibrous layer is disclosed. The first layer is arranged to receive an impact from a large projectile prior to the second layer and engages the projectile to slow its velocity. The second layer is substantially coextensive with the first and dissipates the incoming energy of the impact to resist complete penetration of the second layer by the projectile, preferably by deforming in response to the impact. Both layers comprise fibers having a tensile modulus of at least about 200 g/d, and an energy-to-break of at least about 8 J/g and a tenacity equal to or greater than about 10 g/d. In another embodiment, the layers are reversed relative to the impact face of the system so that the second layer becomes the first layer and is resistant to projectiles impacting the system, while the first layer becomes the second layer and resists deformation of the system by projectile impacts. Any projectile which completely penetrates the first layer is engaged by the second layer to slow its velocity and prevent complete penetration of the second layer. This armor system provides excellent ballistic resistance with enhanced deformation control.
