Abstract

Projectile resistant structure (1) comprises a plurality of stacked flexible shield layers (20). Layers (20) are in general not bonded to one another, so that when a first of such layers is struck by spinning projectile (1) the layer acts without significant structural or other support from any other layers in countering the rotation of the projectile. Preferred shield layers are comprised of anisotropic puncture-resistant materials, stacked such that the principal axes of the layers are offset from each other, and further include substantially soft, impact-dissipating cores (3) disposed adjacent to one or more shield layers so as to spread the force imposed by an impacting projectile across a broader area of the shielded structure or body than would otherwise be affected by the impact. Cores are preferably water-resistant and less dense than water, such that they float and serve to support the shielded structure or body in water.
