Vehicle armor absorbing energy comprises undulated two or three dimensional structure in metal plastics ceramic or fiber composite whose surface exceeds available insertion surface.

摘要

The geometrical surface of the element available to an impacting shot etc (2) exceeds in length and/or breadth the available insertion surface so the element is more deeply deformed by the projectile. The kinetic energy of the projectile is converted into deforming energy in the element (1). The element presents a three-dimensional centimeter-scale structure similar to a honeycomb. In the case of a two-dimensional structure, this proceeds in waves or quasi-harmonically notably triangular, trapezoidal or sinusoidal waves arranged in the projectile impact direction.
