Abstract
A lightweight hybrid structural energy-absorbing panel having a plurality of layers of soft energy-absorbing material, such as Kevlar, disposed between facesheets with a plurality of rigid rod members extending between the facesheets through the layers of energy-absorbing material to structurally connect the facesheets, such panel to absorb the energy of ballistic projectiles.
Claims17
A structural panel comprising:
- at least one layer of energy-absorbing material capable of absorbing the kinetic energy of high-velocity fragments or projectiles, said material having a top and a bottom surface and said material comprising light weight dry ballistic fibers having no resin impregnation;
- a bottom inner rigid structural facesheet disposed on the bottom surface of said layer;
- a top outer rigid structural facesheet disposed on the top surface of said layer;
- and
- a plurality of closely spaced rigid rod members attached to and extending from the bottom of the top facesheets piercing through said layer of energy-absorbing material to structurally connect said top and bottom facesheets.
